Các ví tiền ảo uy tín nhất trong năm 2020

Các ví tiền ảo uy tín nhất trong năm 2020
Kể từ khi Bitcoin xuất hiện vào năm 2009, nó đã trở thành cái mà mọi người nghĩ đến đầu tiên khi nhắc đến tiền điện tử hoặc blockchain. Các loại tiền điện tử như Bitcoin có tính biến động cao nhưng chúng dường như không biến mất trừ khi đánh sập toàn bộ hệ thống Internet trên thế giới. Ngày nay một Bitcoin có giá trị hàng nghìn đô la. Khi các loại tiền điện tử như Bitcoin tiếp tục tồn tại hoặc thậm chí tăng giá trị, các cá nhân rất có nhu cầu quan tâm đến việc sở hữu chúng nhưng điều quan trọng là họ muốn biết được cách lưu trữ Bitcoin một cách an toàn. Để đáp ứng nhu cầu của những người muốn đầu tư vào Bitcoin một cách an toàn, chúng tôi đã tập hợp một danh sách các thiết bị lưu trữ và hay còn gọi là các ví tiền ảo uy tín nhất.
Có nhiều ví có tính năng rất tốt bao gồm khả năng lưu trữ nhiều loại tiền điện tử hơn mà không chỉ có Bitcoin, cũng như các biện pháp bảo mật bổ sung. Danh sách này không theo thứ tự cụ thể nào khác chỉ có đề cập đến ví nóng trước, nhưng điều đó không có nghĩa là ví nóng tốt hơn. Hiện tại, ví nóng được nhận xét là kém an toàn hơn để thực hiện các giao dịch nhanh chóng và ví lạnh là an toàn hơn để lưu trữ trong thời gian dài hơn. Trước hết chúng ta nên tìm hiểu về các khái niệm này trước khi chọn ví vì đó chính là chìa khóa để chọn được một phương tiện lưu trữ an toàn.

Các loại ví tiền ảo

Có 2 loại ví tiền ảo cơ bản đang được sử dụng trong thị trường lưu trữ tiền ảo.

Hot Wallets – Ví nóng

Ví trực tuyến còn được gọi là ví “nóng”. Ví nóng là ví chạy trên các thiết bị có kết nối internet như máy tính, điện thoại hoặc máy tính bảng. Điều này có thể tạo ra lỗ hổng bảo mật vì những ví này tạo ra khóa riêng cho tiền của bạn trên các thiết bị kết nối internet này. Mặc dù ví nóng có thể rất thuận tiện trong cách bạn có thể truy cập và thực hiện các giao dịch với tài sản của mình một cách nhanh chóng, nhưng chúng cũng thiếu bảo mật.
Điều này nghe có vẻ xa vời, nhưng những người không sử dụng đủ bảo mật khi sử dụng các ví nóng này có thể bị đánh cắp tiền. Ví dụ: Khoe khoang trên một diễn đàn công khai như Reddit về số lượng Bitcoin bạn nắm giữ trong khi bạn đang sử dụng ít hoặc không có bảo mật cho ví của mình và lưu trữ nó trong một ví nóng sẽ không phải là điều khôn ngoan.
Những ví này được sử dụng cho một lượng nhỏ tiền điện tử. Bạn có thể ví một ví nóng với một tài khoản séc. Sự khôn ngoan về tài chính thông thường cho rằng chỉ giữ tiền tiêu trong tài khoản séc trong khi phần lớn tiền của bạn nằm trong tài khoản tiết kiệm hoặc tài khoản đầu tư khác. Điều tương tự cũng có thể nói đối với ví nóng. Ví nóng bao gồm thiết bị di động, máy tính để bàn, web và hầu hết các ví lưu ký trao đổi.
Điều quan trọng cần lưu ý ở đây là việc giữ tiền điện tử trong ví trao đổi không giống như giữ nó trong ví cá nhân của bạn. Ví trao đổi là tài khoản lưu ký do sàn giao dịch cung cấp. Người dùng của loại ví này không phải là người nắm giữ khóa cá nhân của tiền điện tử được giữ trong ví này.
Nếu một sự kiện xảy ra khi sàn giao dịch bị tấn công hoặc tài khoản của bạn bị xâm phạm, tiền của bạn sẽ bị mất. Cụm từ “not your keys not your coin” là một khái niệm được lặp lại nhiều trong các diễn đàn tiền điện tử. Việc giữ một lượng lớn tiền điện tử trong bất kỳ ví nóng nào, đặc biệt là tài khoản trao đổi là không khôn ngoan. Mà thay vào đó, bạn nên rút phần lớn tiền về ví “lạnh” cá nhân của mình (giải thích bên dưới). Các “ví” trao đổi bao gồm Coinbase, Gemini, Binance và nhiều loại khác. Mặc dù các ví này được kết nối với Internet, có sự tấn công tiềm ẩn nhưng chúng vẫn rất hữu ích cho khả năng nhanh chóng thực hiện các giao dịch hoặc giao dịch tiền điện tử.

Các loại ví tiền ảo

Cold Wallets – Ví lạnh

Loại ví tiếp theo sẽ được đề cập ở đây là ví lạnh. Mô tả đơn giản nhất về ví lạnh là ví không được kết nối với Internet và do đó nguy cơ bị xâm phạm thấp hơn nhiều. Những ví này cũng có thể được gọi là ví ngoại tuyến hoặc ví cứng. Các ví này lưu trữ địa chỉ và khóa cá nhân của người dùng trên một thứ không được kết nối với Internet và thường đi kèm với phần mềm hoạt động song song để người dùng có thể xem danh mục đầu tư của họ mà không gây rủi ro cho khóa cá nhân của họ.
Có lẽ cách an toàn nhất để lưu trữ tiền điện tử ngoại tuyến là thông qua ví giấy. Ví giấy là một ví mà bạn có thể tạo ra từ một số trang web nhất định. Sau đó, nó tạo ra cả khóa công khai và khóa riêng tư mà bạn in ra trên một tờ giấy. Khả năng truy cập tiền điện tử trong các địa chỉ này chỉ có thể thực hiện được nếu bạn có mảnh giấy đó. Nhiều người cán mỏng những chiếc ví giấy này và cất chúng trong két an toàn tại ngân hàng hoặc thậm chí trong két sắt trong nhà. Ví giấy không có giao diện người dùng tương ứng ngoài một tờ giấy, vì vậy với mục đích của bài viết này, chúng tôi tập trung vào các phương pháp lưu trữ lạnh khác như ví cứng.
Ví cứng thường là một thiết bị USB lưu trữ khóa cá nhân của người dùng một cách an toàn. Điều này có lợi thế hơn so với ví nóng vì nó không bị ảnh hưởng bởi vi-rút có thể có trong máy tính của một người vì khóa riêng không bao giờ tiếp xúc với máy tính được kết nối mạng của bạn hoặc phần mềm có khả năng bị tấn công. Các thiết bị này cũng thường là mã nguồn mở, cho phép cộng đồng xác định độ an toàn của nó thay vì một công ty tuyên bố rằng nó an toàn để sử dụng.
Ví lạnh là cách an toàn nhất để lưu trữ Bitcoin hoặc các loại tiền điện tử khác của bạn. Tuy nhiên chúng yêu cầu thêm một chút kiến ​​thức để thiết lập. Điều cần thiết đối với bất kỳ ai quan tâm đến việc sở hữu tiền điện tử là tìm hiểu về cách lưu trữ an toàn và các khái niệm về cả ví nóng và ví lạnh. Một khi bạn nghĩ rằng bạn đã sẵn sàng để tiếp tục tìm hiểu thì các ví được liệt kê dưới đây là một số ví tiền ảo uy tín nhất trong ngành mà chúng tôi đã sưu tầm được.

Các ví tiền ảo uy tín trong năm 2020

Các ví tiền ảo uy tín nhất năm 2020
Dưới đây là một số ví tiền ảo được người dùng đánh giá là uy tín và nên sử dụng trong năm nay. Cùng phân tích và đánh giá để có cái nhìn khách quan nhất khi lựa chọn sử dụng ví.

Exodus – Một trong các ví tiền ảo tốt nhất cho người mới bắt đầu

  • Loại ví: Ví nóng
  • Chi phí mua: Miễn phí
  • Tương thích với ví cứng: Trezor
  • Trao đổi hợp nhất: Có
Exodus là một ví điện thoại di động và máy tính để bàn có giao diện người dùng rất đơn giản và tích hợp sẵn một sàn giao dịch. Một trong những tính năng phổ biến nhất của Exodus là khả năng hoán đổi giữa một số lượng ngày càng tăng các loại tiền điện tử. Exodus hiện cho phép hoán đổi giữa hơn 100 loại tiền điện tử khác nhau.
Với sự đơn giản của nó, ví này rất phù hợp cho những người mới bắt đầu tham gia vào ngành tiền điện tử. Nó cũng có sự hỗ trợ tuyệt vời, đây là một tính năng cần thiết cho những người mới bắt đầu tham gia vào cái mà nhiều người sẽ coi là một thị trường khó hiểu.
Mặc dù nó rất tốt cho người mới bắt đầu, nhưng những người dùng cao cấp hơn có thể thấy nó thiếu một số tính năng. Đầu tiên, Exodus là một ví mã nguồn đóng. Điều này đi ngược lại đặc điểm của ý tưởng về Bitcoin và blockchain và có thể tạo ra một số lo ngại về bảo mật vì mã của nó không mở cho mọi người xem. Thay vào đó, người dùng dựa vào nhóm Exodus để đảm bảo không có lỗ hổng nào trong bảo mật ví của họ.Exodus có tùy chọn phí tùy chỉnh ngoài việc tự động đặt phí để đảm bảo giao dịch hoàn tất nhanh chóng.
Ưu điểm
  • Nhiều loại tiền điện tử
  • Trao đổi tích hợp
  • Hỗ trợ khách hàng tốt
Nhược điểm
  • Mã nguồn đóng

Electrum – Ví tiền ảo tốt nhất cho người dùng nâng cao quan tâm đến Bitcoin

  • Loại ví: Ví nóng
  • Chi phí mua: Miễn phí
  • Tương thích với ví cứng: thiết bị Trezor và Ledger
  • Trao đổi hợp nhất: Không
Electrum là một trong những ví Bitcoin ban đầu. Nó đã xuất hiện từ năm 2011, hai năm sau khi Bitcoin được tạo ra và đã thay đổi rất ít kể từ đó. Mặc dù ví này còn sơ khai về giao diện người dùng và cam kết chỉ dành cho Bitcoin, nhưng nó lại vượt trội ở chức năng chính này. Electrum cũng phù hợp hơn với người dùng cao cấp do các tùy chọn phức tạp của nó.
Electrum sử dụng mã nguồn mở, cho phép người dùng đặt phí giao dịch tùy chỉnh và có tùy chọn để chọn giữa Bitcoin kế thừa và Segwit. Nó cũng cung cấp cho người dùng khả năng xác định mức độ bảo mật mà họ muốn sử dụng. Ví dụ: bạn có thể tạo ví tiêu chuẩn, ví có xác thực hai yếu tố hoặc ví đa chữ ký. Electrum là ví hoàn hảo cho người nắm giữ Bitcoin cao cấp hơn, những người muốn có các tính năng bảo mật tuyệt vời và khả năng tùy chỉnh trong một bố cục đơn giản.
Ưu điểm
  • Khả năng đặt phí giao dịch tùy chỉnh
  • Mức độ bảo mật cao hơn hầu hết các ví nóng
  • Khả năng tùy chỉnh Seed Phrase
Nhược điểm
  • Giao diện người dùng rất cơ bản
  • Chỉ hoạt động với Bitcoin
  • Không hỗ trợ khách hàng

Mycelium – Một trong các ví tiền ảo tốt nhất cho người dùng di động

  • Loại ví: Ví nóng
  • Chi phí mua: Miễn phí
  • Tương thích với ví cứng: thiết bị Trezor và Ledger
  • Trao đổi hợp nhất: Có
Mycelium là một ví Bitcoin có mã nguồn mở và chỉ dành cho thiết bị di động. Mycelium hiện chỉ hỗ trợ Bitcoin. Về mặt nào đó, Mycelium khá giống với ví Electrum với một số điểm khác biệt là nó chỉ dành cho thiết bị di động còn giao diện người dùng được làm mới hơn ví Electrum và cũng có một sàn tiền ảo tích hợp.
Mycelium giống như Electrum là một trong những ví xuất hiện sớm hơn trong ngành tiền ảo. Cũng giống như Electrum, người dùng có thể đặt phí giao dịch tùy chỉnh để có thể chọn khoảng thời gian bạn sẵn sàng đợi giao dịch được hoàn thành. Mycelium cũng có một số tính năng thú vị hơn như hỗ trợ ví cứng, cho phép người dùng giữ Bitcoin của họ trong thiết bị lưu trữ ngoại tuyến trong khi vẫn sử dụng giao diện người dùng của Mycelium để xem tài sản của họ.
Ưu điểm
  • Khả năng đặt phí giao dịch tùy chỉnh
  • Khả năng sử dụng ví phần cứng
  • Phần mềm mã nguồn mở
Nhược điểm
  • Chỉ sử dụng được trên điện thoại di động
  • Chỉ hoạt động với Bitcoin
  • Có thể gây nhầm lẫn cho người dùng lần đầu

Ledger Nano X – Ví cứng tốt nhất

  • Loại ví: Ví lạnh
  • Chi phí mua: $ 119
  • Trao đổi hợp nhất: Không
Ledger Nano X là ví cứng thế hệ thứ hai của Ledger, một công ty của Pháp đã tham gia vào ngành tiền điện tử trong vài năm. Sản phẩm đầu tiên của Ledger là Ledger Nano S, một trong những ví cứng đầu tiên trên thị trường và đã thống trị ngành tiền ảo trong một số năm.
Nano X giống một chiếc USB và kết nối với thiết bị của bạn qua cổng USB hoặc Bluetooth. Điều này có nghĩa là bạn có thể kết nối ví với thiết bị iOS hoặc Android của mình và không cần máy tính. Nó hỗ trợ tốt hơn 1.500 loại tiền điện tử. Danh sách này tiếp tục tăng lên mỗi năm khi cộng đồng yêu cầu hỗ trợ cho các loại tiền điện tử yêu thích của họ.
Mặc dù bản thân thiết bị là một chiếc ví cứng lưu trữ lạnh nhưng nhóm Ledger đã tạo ra phần mềm Ledger Live cung cấp giao diện người dùng cho tất cả tài sản của bạn. Điều này cung cấp cho người dùng khả năng thêm ví mới cho các loại tiền điện tử khác nhau vào thiết bị của họ và quản lý danh mục đầu tư của họ. Ví cứng Ledger đã và đang là ví phổ biến nhất trong ngành. Ledger cũng đi kèm với cáp USB Type-C để nó có thể được kết nối với máy tính để bàn hoặc điện thoại thông minh nếu không dùng được Bluetooth.
Ưu điểm
  • Ledger Live có giao diện người dùng trực quan và tiện lợi
  • Có thể có tới 100 ứng dụng khác nhau được lưu trữ đồng thời
  • Phần mềm nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
  • Sự thuận tiện khi kết nối Bluetooth
Nhược điểm
  • Một số người trong cộng đồng tiền điện tử tin rằng tích hợp Bluetooth là một phương thức tấn công tiềm ẩn, mặc dù có thể lựa chọn USB
  • Tính năng Bluetooth tăng thêm sự tiện lợi nhưng không mượt mà
  • Thiết bị Ledger chỉ cho phép bạn lưu trữ đồng thời một số lượng ví nhất định

Trezor Model T – Ví tiền ảo tốt nhất để lưu trữ một số lượng lớn tiền điện tử

  • Loại ví: Ví lạnh
  • Chi phí mua: $ 170
  • Trao đổi hợp nhất: Có
Trezor giống như Ledger, là một cái tên đồng nghĩa với lưu trữ ví lạnh tiền điện tử. Model T của nó là thế hệ thứ hai của ví cứng mà họ đã tạo ra. Trezor Model T rất giống với Ledger, nhưng nó cung cấp cho người dùng khả năng truy cập các sàn giao dịch của bên thứ ba như Changelly và Shapeshift, trực tiếp trong giao diện trang web của nó. Mặc dù điều này khá thuận tiện nhưng nó khó có thể biện minh cho mức giá đắt hơn 170 đô la của mình.
Model T sử dụng màn hình cảm ứng, có thể dễ sử dụng cho người mới bắt đầu hơn so với các nút mà Model trước đã sử dụng. Trezor cũng có một khe cắm thẻ MicroSD, cho phép bạn sử dụng thẻ MicroSD để mã hóa mã PIN và bảo vệ thiết bị của bạn khỏi các cuộc tấn công.
Giống như Ledger Nano X, Trezor Model T cũng đi kèm với cáp USB Type-C để bạn có thể kết nối với điện thoại thông minh hoặc máy tính để bàn của mình. Hiện tại, Trezor Model T hỗ trợ gần 1.400 loại tiền điện tử khác nhau. Một số người cho rằng Model T an toàn hơn một chút so với Ledger Nano X do kết nối Bluetooth. Điều đó nói rằng, người dùng Ledger có thể chỉ cần tránh sử dụng Bluetooth nếu họ muốn an toàn hơn.
Ưu điểm
  • Giao diện người dùng dựa trên web với các trao đổi được tích hợp sẵn
  • Một danh sách khổng lồ các loại tiền điện tử được hỗ trợ
  • Phần mềm mã nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
  • Không giới hạn số lượng ví bạn có thể có đồng thời
Nhược điểm
  • Mặc dù nó là một ví cứng tuyệt vời, nhưng giá của nó có vẻ hơi cao
  • Màn hình cảm ứng nhỏ có thể khiến bạn khó gõ
  • Ví cứng có thể gây nhầm lẫn cho người dùng lần đầu tiên

Ledger Nano S: Lựa chọntốt nhất cho túi tiền của bạn

  • Loại ví: Ví lạnh
  • Chi phí mua: $ 59
  • Trao đổi hợp nhất: Không
Ledger Nano S là thế hệ ví cứng đầu tiên được Ledger giới thiệu. Nó cũng là một trong những ví cứng đầu tiên từng được tạo ra. Nó tiếp nối ngay sau thế hệ đầu tiên của Trezor. Giống như người kế nhiệm, Nano S tương thích với hàng nghìn loại tiền điện tử. Nano S không đi kèm với cáp USB type-C, vì vậy người dùng sử dụng điện thoại thông minh hiện đại hơn có thể gặp khó khăn khi kết nối với thiết bị của họ.
Nano S về cơ bản giống với người kế nhiệm của nó là Nano X ở chỗ nó hỗ trợ cùng một danh sách các loại tiền điện tử và có quyền truy cập vào phần mềm Ledger Live. Các tính năng mà nó thiếu là kết nối Bluetooth và bạn có thể có bao nhiêu ví đồng thời hoạt động trên thiết bị của mình. Với Nano X, người dùng có thể lưu trữ đồng thời 100 ví. Với Nano S, bạn chỉ có thể lưu trữ tối đa 18.
Nano S chỉ có đủ dung lượng lưu trữ để tạo ví cho một số lượng tiền điện tử giới hạn tại một thời điểm. Nếu bạn xóa ví để thêm một loại tiền điện tử khác, bạn sẽ không mất tiền điện tử trong ví mà bạn đã xóa. Điều này là do tiền điện tử đó được lưu trữ trực tiếp trên blockchain.
Ví đã xóa và tiền điện tử trong đó vẫn có thể được nhìn thấy trong Ledger Live, nhưng ví sẽ không được nhìn thấy trên chính thiết bị Ledger. Điều này có nghĩa là nếu bạn muốn gửi hoặc nhận từ ví bạn đã xóa, bạn có thể phải xóa ví khác để có thêm dung lượng.
Điều đó nói rằng, Ledger Nano S vẫn là một chiếc ví tuyệt vời cho những người muốn lưu trữ tiền điện tử của họ một cách an toàn với một mức giá hợp lý. Nó cũng khá dễ sử dụng với Ledger Live, làm cho nó trở thành một sản phẩm lý tưởng cho người mới bắt đầu tìm kiếm cách lưu trữ an toàn và đơn giản cho một số ít tiền điện tử.
Ưu điểm
  • Ledger Live có giao diện người dùng trực quan và tiện lợi
  • Lưu trữ tiền điện tử an toàn với mức giá thấp
  • Phần mềm mã nguồn mở với lợi ích bổ sung là hỗ trợ khách hàng và cộng đồng
Nhược điểm
  • Chỉ có thể lưu trữ tối đa 18 ví cùng một lúc
  • Nano S không có tính năng Bluetooth

Day 4: I will repost this guide daily until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. ARE YOU PART OF THE SOLUTION? News: Unconfirmed TX's @ 174K, more exchanges adding SegWit, Core prioritizes SegWit GUI

NOTE Just a daily repost because original OP Bastiat seems to be offline (due to holidays I guess). However, this is quite important as I see much misinformation on which exchanges use segwit or not. Please upvote for awareness.
BACKGROUND
Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make it happen. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin
IMPORTANT NOTE: The mempool is currently overflowing. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange
SELECTED TOP EXCHANGES BY SEGWIT & BATCHING STATUS
There are 2 different Segwit address formats.
  • p2sh - starting with a "3..."
  • bech32 - starting "bc1..."
Not many wallets/exchanges support bech32 yet and will claim the address is invalid if you try to send to it. bech32 ("native Segwit") is a mildly better solution compared to p2sh.

If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Transaction if the sending address is a SegWit address.
    Source
So what address can I send to safely, there is so much confusion?
  • As of right now...
Non-Segwit Transactions
non-Segwit address to…
non-Segwit address OK
3..... (Segwit) OK
bc1.... (Segwit) No (no support for them yet)
Segwit Transactions
3... address (Segwit) to…
non-Segwit address OK
3..... (Segwit) OK
bc1.... (Segwit) No (no support for them yet)
bc1... address (Segwit) to…
non-Segwit address OK
3..... (Segwit) OK
bc1.... (Segwit) OK
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?

Day 5: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and transaction fees are low. User demand from this community can help lead to some big changes. Have you joined the /r/Bitcoin SegWit effort?

SUMMARY
Segregrated Witness (SegWit) was activated on the Bitcoin network August 24, 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work. If users demand SegWit now it will temporarily releive the transaction backlog while bigger solutions like Lightning are developed.

  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.

What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?

Edit: Updated Segwit Exchange Status for Binance and HitBTC
submitted by Bastiat to Bitcoin [link] [comments]

Day 9: I will post this guide regularly until available solutions like SegWit, order batching, and Lightning payment channels are mass adopted, the mempool is empty once again, and tx fees are low. Have you done your part?

BACKGROUND
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, and the majority of users have not made the switch themselves.
On Dec 18 2017 Subhan Nadeem has pointed out that: If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
Mass SegWit use alone could empty the mempool, result in blocks that are not completely full, and make it possible to include transactions with $0 fee once again.
On Jan 11 2018 when BTC sends went offline at Coinbase the mempool began to rapidly empty. Later in the day when service was restored there was a sharp spike up in the mempool. Subsequently, that afternoon Brian Armstrong finally had to break his silence on the topic and admitted Coinbase is working on SegWit but has still not deployed it. It appears that this is an important data point that indicates if just a few major exchanges would deploy SegWit the high fees bitcoin is experiencing would be eliminated.
SegWit is just one technique available to exchanges and users to reduce pressure on the Bitcoin network. You can make the switch to SegWit on your next transaction, and pressure exchanges to deploy SegWit NOW along with other actions that will reduce their transaction impact on the network. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. If your wallet is not committed to implementing SegWit fast, speak out online any way you can and turn up the pressure. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Contact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch. Use social media to point out the benefits of SegWit adoption.
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.
BEYOND SEGWIT - BATCHING, PAYMENT CHANNELS, LIGHTNING
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it. Users should demand this or walk.
Beyond SegWit & Batching, Lightning Network integration will have even more effect. Lightning is now active and exchanges could setup payment channels between each other so that on-chain transactions need not take place. Some ideas have to outline how that might work are here: Google Doc - Lightning Exchanges. Which two bitcoin exchanges will be the first to establish a lightning channel between themselves and offer free/instant transfers between them for their customers? This will happen in 2018

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unnecessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download the latest version of Electrum to generate a SegWit address.
A transaction between two SegWit addresses is a SegWit transaction.

P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to exist wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
P2SH starts with "3..."
bech32 starts with "bc1..."
Which addresses can I send from/to?
P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backward compatibility
bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

Day 7: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Do you want low tx fees, because this is how you get low tx fees

TL/DR
Bitcoin users can help lower transaction fees and improve bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.
MEMPOOL/SEGWIT STATISTICS
BACKGROUND
On Dec 18 Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make 80%+ SegWit happen fast. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Conact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.

FAQs
If I'm a HODLer, will it help to send my BTC to a SegWit address now?
  • No, just get ready now so that your NEXT transaction will be to a SegWit wallet. Avoid burdening the network with any unneccessary transactions for now.
Why is SegWit adoption going so slowly? Is it a time-consuming process, is there risk involved, is it laziness, or something else?
  • SegWit will require some extra work to be done right and securely. Also, most exchanges let the user pay the fee, and up to now users have not been overly concerned about fees so for some exchanges it hasn't been a priority.
Once Segwit is FULLY adopted, what do we see the fees/transaction times going to?
  • Times stay the same - fees will go down. How much and for how long depends on what the demand for transactions will be at that time.
What determines bitcoin transaction fees, to begin with?
  • Fees are charged per byte of data and are bid up by users. Miners will typically include the transaction with the highest fee/byte first.
Can you please tell me how to move my bitcoins to SegWit address in Bitcoin core wallet? Does the sender or receiver matter?
  • The Bitcoin core wallet does not yet have a GUI for its SegWit functionality. Download Electrum v3.0.3 to generate a SegWit address.
    A transaction between two SegWit addresses is a SegWit transaction.
    A transaction sent from a SegWit address to a non-SegWit address is a SegWit transaction.
    A transaction sent from a non-SegWit address to a SegWit address is NOT a SegWit transaction. You can send a SegWit Tx if the sending address is a SegWit address.
    Source: HowToToken
What wallet are you using to "batch your sends"? And how can I do that?
  • Using Electrum, the "Tools" menu option: "Pay to many".
    Just enter your receive addresses and the amounts for each, and you can send multiple transactions for nearly the price of one.
Why doesn't the Core Wallet yet support SegWit?
  • The Core Wallet supports SegWit, but its GUI doesn't. The next update will likely have GUI support built-in
Why isn't a large exchange like Coinbase SegWit ready & deployed when much smaller exchanges already are? Why do they default to high fees? Where is the leadership there?
P2SH/bech32 FAQs
What are the two SegWit address formats and why do they exist?
  • It's been a challenge for wallet developers to implement SegWit in a way that users can easily and without too much disruption migrate from legacy to SegWit addresses. The first wallets to enable SegWit addresses – Ledger, Trezor, Core, GreenAddress – use so-called “nested P2SH addresses.” This means they take the existing Pay 2 Script Hash address – starting with a “3” – and put a SegWit address into it. This enables a high grade of compatibility to existing wallets as every wallet is familiar with these addresses, but it is a workaround which results in SegWit transactions needing around 10 percent more space than they otherwise would.
    Electrum 3.0 was the first wallet to use bech32 addresses instead of nested p2sh addresses.
    Source: BTCManager.com
What is the difference in address format between SegWit address formats P2SH and bech32?
  • P2SH starts with "3..."
    bech32 starts with "bc1..."
Which addresses can I send from/to?
  • P2SH Segwit addresses can be sent to using older Bitcoin software with no Segwit support. This supports backwards compatibility
    bech32 can only be sent to from newer Bitcoin software that support bech32. Ex: Electrum
    Source: BitcoinTalk.org
Why did ThePirateBay put up two Bitcoin donation addresses on their frontpage, one bech32 and one not?
  • The address starting with a "3..." is a P2SH SegWit address that can be sent BTC from any bitcoin address including a legacy address. The address starting with a "bc1..." is a bech32 SegWit address that can only be sent to from newer wallets that support bech32.

PREVIOUS DAY'S THREADS
There's lots of excellent info in the comments of the previous threads:
submitted by Bastiat to Bitcoin [link] [comments]

Day 6: I will post this guide regularly until available solutions like SegWit & order batching are mass adopted, the mempool is empty once again, and tx fees are low. Refer a friend to SegWit today. There's no $10 referral offer, but you'll both get lower fees and help strengthen the BTC protocol

TL/DR
Bitcoin users can help lower transaction fees and contribute to bitcoin by switching to SegWit addresses and encourage wallets/exchanges to do the same.
SUMMARY
Segregated Witness (SegWit) was activated on the Bitcoin network August 24 2017 as a soft fork that is backward compatible with previous bitcoin transactions (Understanding Segregated Witness). Since that time wallets and exchanges have been slow to deploy SegWit, some admitting in December 2017 that they have not even started work on integrating it. Others, such as Zebpay in India have already implemented SegWit and are reaping the benefits of reduced transaction fees. If bitcoin users demand SegWit now it will temporarily relieve the transaction backlog while more even more advanced solutions such as Lightning are developed.
Batching is another great way that exchanges can reduce their fees. See: Saving up to 80% on Bitcoin transaction fees by batching payments. Despite the benefits of batching, some exchanges have been slow to implement it.
There is an opportunity now for all bitcoin users to individually contribute to help strengthen and improve the bitcoin protocol. At this point, the process requires a bit of work/learning on the part of the user, but in doing so you'll actually be advancing bitcoin and leaving what could turn out to be a multi-generational legacy for humanity.
MEMPOOL/SEGWIT STATISTICS
BACKGROUND
On Dec 18 Subhan Nadeem has pointed out that:
If every transaction in the Bitcoin network was a SegWit transaction today, blocks would contain up to 8,000 transactions, and the 138,000 unconfirmed transaction backlog would disappear instantly. Transaction fees would be almost non-existent once again.
A few thousand bitcoin users from /Bitcoin switching to making their next transactions SegWit transactions will help take pressure off the network now, and together we can encourage exchanges/wallets to rapidly deploy SegWit for everyone ASAP. Let's make 80%+ SegWit happen fast. You can help by taking one or more of the action steps below.
ACTION STEPS
  1. If your favorite wallet has not yet implemented SegWit, kindly ask them to do so immediately. In the meantime start using a wallet that has already implemented SegWit.
  2. If your favorite exchange has not yet implemented SegWit, try to avoid making any further purchases of bitcoin at that exchange and politely inform them that if they do not enable SegWit within 30-days they will lose your business. Sign-up for an account at a SegWit deployed/ready exchange now and initiate the verification process so you'll be ready to bail
  3. Help educate newcomers to bitcoin about the transaction issue, steer them towards SegWit wallets from day one, and encourage them to avoid ever purchasing bitcoin through non-SegWit ready exchanges that are harming bitcoin.
  4. Spread the word! Conact individuals, websites, etc that use bitcoin, explain the benefits of SegWit to everyone, and request they make the switch
IMPORTANT NOTE: The mempool is currently still quite backlogged. If you are a long-term holder and really have no reason to move your bitcoins at this time, wait until the mempool starts to clear and transaction fees go down before moving your bitcoins to a SegWit address or SegWit friendly exchange.

Tips para los que quieren iniciar en criptomonedas - Enero 2018

En vista del aumento de interés que ha tenido el tema últimamente he decidido aportar lo que he aprendido en los pocos meses que llevo en esto. Estoy lejos de ser un experto pero espero poder ayudar en algo a los interesados, que han sido bastantes. Trataré de no extenderme mucho y tocar varios puntos clave.

¿Qué compro?

Para mi, tienes tres opciones principales hoy en día.
Bitcoin: La vieja confiable. Su gran problema actual son las transferencias lentas y las comisiones altas. Hay iniciativas que buscan normalizar la situación pero esto durará algunos meses más, como mínimo.
Ethereum: Alternativa sólida. Comisiones más bajas. Ligeramente más difícil de adquirir.
Bitcoin Cash: Comisiones bajas y tiene tiempos de confirmación más rápidos para las transferencias. La recomiendo solo para este fin.

Quiero comprar, ¿cómo hago?

Con bolívares
Tienes varias opciones acá. LocalBitcoins es la más común. Creas tu cuenta y puedes comenzar a comprar en Bs. a cualquiera de los vendedores calificados que se adapte a lo que necesitas (mayormente que estén en el límite que dispones y que tengan cuenta en tu banco). Posee un sistema de reputación fácil de entender y le tomas el hilo rápido. El gran problema acá es que si deseas retirar tus fondos, Bitcoin está actualmente pasando un período donde las comisiones están bastante altas, y las transferencias tardan bastante en confirmarse.
También puedes comprar con Bs. en LocalEthereum. El concepto es el mismo, aunque la oferta de vendedores/compradores es menor. Sin embargo, las comisiones de Ethereum son bastante más bajas que Bitcoin.
La última es depósitar fondos en AirTM. De ahí pasarlos a Uphold y alli cambiar por tu criptomoneda de opción. Es la que menos recomiendo por las comisiones que se lleva la página y los cajeros que efectúan los cambios. Lo bueno es que la plataforma es sólida y segura. Esta opción debes usarla si deseas comprar Bitcoin Cash. No se como estará funcionando para Venezuela LocalBitcoinCash.
Con dólares en PayPal
AirTM suele ser la opción principal aquí, pese al tema de los fees. Igual puedes usar LocalBitcoins y LocalEthereum para esto, pero la oferta es más escasa. De igual manera depende de los montos que desees cambiar y entren en los límites que acepta el vendedor.

Ya compré mis criptomonedas. ¿Qué hago?

Lo primero es asegurar tus fondos. Muchos recomiendan no dejar tu plata en manos de un tercero, y tienen razón. Sin embargo, hoy día tanto LocalBitcoins como Uphold son bastante confiables, aunque no infalibles. Si dejas tus monedas en dichas páginas, asegúrate de activar 2FA (Two factor authentication). De esta manera cada vez que se haga un retiro tendrás que verificarlo en tu teléfono o dispositivo.
Si decides retirar a una billetera personal, tienes que ser muy responsable guardando tus frases de recuperación o llaves privadas. Si las pierdes y olvidas el password para acceder a tu billetera, nadie podrá ayudarte a recuperar esos fondos.
Para BTC, recomiendo Electrum. Es fácil de instalar y tiene cliente para Android también. También existe Electrum Cash para Bitcoin Cash.
Para Ethereum, recomiendo ingresar a MyEtherWallet.com y crear una billetera allí (revisa bien ese enlace, es una de las víctimas más comunes para phishing en todo el cripto).
Existen opciones que almacenan varios coins de una forma sencilla, como Coinomi, que es una app para Android. Es cómoda y soporta muchísimas monedas, entre ellas las más populares, incluídas las de este post. De igual manera, vigila tu seguridad, quién tiene acceso a tu teléfono y demás.

Avanzado: Quiero invertir en criptomonedas alternativas

Añade a tus marcadores https://coinmarketcap.com/ Esa será tu biblia.
Mis recomendaciones son investigar bien en cuál es la criptomoneda que deseas comprar. Revisa su website, investiga sobre el team, googlea, busca en YouTube, ve sus redes sociales, revisa si tiene un subreddit, etc. A esto le llaman DYOR (do your own research). Vigila que tenga un roadmap claro y de preferencia que sea un proyecto que resuelve un problema o tiene aplicación en el mundo real. Los proyectos buenos siempre van al alza con el tiempo.
En Coinmarketcap puedes ver donde se vende cada moneda. Los exchanges más populares hoy día son Bittrex, Binance, HitBTC, Poloniex, Kraken, Bitstamp. Otros en ascenso como KuCoin se están posicionando bien. Para comprar, simplemente transfieres de tus fondos en LocalBitcoins/Ethereum/Uphold o tus billeteras a la billetera que te asigna cada exchange para la moneda que estés usando y listo, tienes tus fondos disponibles. Para saber como comprar ya dentro del exchange, recomiendo ver guías en YouTube. Puede parecer complicado pero se domina rápido.
Nunca metas dinero que no te puedes permitir perder. No tengas miedo si compras y de repente baja el precio. Esto es normal, e incluso pasa con las monedas grandes. Recuerda que no pierdes dinero hasta que vendes. Mucha paciencia. El mercado, aún con correcciones y dips relativamente fuertes, está en tendencia al alza y no se ve que vaya a parar en el horizonte visible. Este año apunta a ser aún mejor que el anterior, así que estás a tiempo de ingresar y mantener una posición en criptomonedas.
Si hay más dudas puedo ir ayudando en lo que pueda en los comentarios.

Best Bitcoin Wallets

Best Bitcoin Wallets

https://preview.redd.it/w9ztf3nlraf31.png?width=512&format=png&auto=webp&s=4884c7fc9446bf2d53a448dab43aa7990bcdde7b
Bitcoin continues to amaze the world and offers us a cash option, as opposed to the state-dominated money we use as a daily standard. Advocates argue that advanced currency standards are simpler, more secure, and offer preferential protection over traditional currency standards. In the last few years speculation has emerged as an open gate for some people's radars, as a Bitcoin forecast in contrast to the USD and forecasts of different monetary forms have increased. Before putting a dollar in Bitcoin or other digital money, it is imperative to understand the dangers. Bitcoin can cause a double increase in incentives over the next few years, but it can only be left to focus on value. Just put what you lose, because there's an opportunity you can't get back. If you understand the dangers and are ready to move forward, any of these best Bitcoin wallets should keep you safe.

Hardware Wallets - Ledger & Trezor

Bitcoin hardware wallets are a carefully designed electronic device that aims to store the secret keys of your coins in a disconnected environment. With these wallets, special keys and advanced signs are required to spend Bitcoin. As with any wallet, you should save the word seed on a piece of paper and store it in a protected place. Distribute favorites by making several copies. Moreover, as the switches are disconnected, there is no possibility of being attacked. During the season of this composition, there was no theft or loss of Bitcoin from the hardware wallet. Some hardware wallets have security network cards, while others have a small advanced display with a user interface to control swaps. Even if your hardware wallet is damaged, you can effectively re-install your Bitcoin device with the word recovery. Bitcoin hardware wallets were developed after Bitcoin was designed. Currently, different digital forms of money in these wallets ETH, LTC, and so on. If you need to store Bitcoin and other encryption money securely over an extended period, you will need to set up a hardware wallet at this point. Because most of these hardware wallets have a waiting period of one or two months due to enormous interest, you should arrange one at the first opportunity.

Atomic Wallet

The Atomic Wallet is a free wallet that supports more than 300 coins and assets. That is the primary encryption wallet with decentralized cross-chain exchanges available. Customers can trade Bitcoin, Litecoin, and QTUM without any middle people. The Atomic Wallet group also aims to strengthen the Ethereum for exchanges. Besides, Atomic Wallet offers an alternative to buying XRP, BTC, LTC, and ETH with natural customary trade management and debit card for digital currency types. Each of these highlights is created in a clear and complete interface. You do not need to check or register your personality. Download, install and start using your Atomic Wallet for your working framework. Atomic Wallet works on frameworks that will be available within the workspace, and will also be accessible for macOS, Linux and Android, and iOS devices. The Atomic Wallet creates a memory aid seed for your wallet and encodes the private keys on your gadget. If you keep your cryptos in the Atomic Wallet, you must save it and keep it in a safe place, since the seed has been shown once and has not been emailed. Atomic Wallet supports private key retrieval so you can easily move your assets from one to the other wallet. Atomic Wallet gives its interface to custom tokens, so everyone can contain custom tokens by bringing a cunning contact address. Atomic Wallet is an unusual digital currency initiative by all accounts. At one point, you can audit more than 300, trade and buy some, try creative Atomic swaps, gain admission to special markers, and be interested in abundance. Each of these highlights is achieved without detention.

Trust Wallet

Trust Wallet is the world's driving multi-resource computerized wallet which stores both Bitcoin and altcoins. It as of now bolsters more than 13 crypto coins and is a perfect decision for multi-digital money clients. With a functioning advancement group working at lightning speed, it's likewise entirely dependable. Altcoins, for example, Binance, Monero, Tether, Ripple, and a lot more are on their improvement guide. Trust Wallet gives a consistent, frictionless, and simple to utilize UI. It takes no email confirmations, no onboarding, and no usernames-passwords to begin utilizing Trust Wallet. It is an HD wallet which accompanies a seed reinforcement key element. The seed key encourages you in controlling and reestablishing your crypto resources on the off chance that your gadget is harmed or lost. You can send out your private keys, and import Bitcoin or altcoins from paper wallets.

Mycelium Wallet

Mycelium is an open-source, built-in Bitcoin wallet with a constantly evolving and working the designer network. That is a frictionless device for eliminating Bitcoin because it does not require email approvals, onboarding, and no username password to get started. Apart from the chance you're new to Bitcoin, Mycelium's user interface is difficult to use, but you'll love anything. You will check your Bitcoin private key and usually receive it when necessary. Mycelium is an HD wallet that offers a 12-word recovery password that you need to record. When you have no chance of damaging or losing your gadget, this supplemental seed switch will help you make up your Bitcoin.

Electrum Wallet

Electrum is a famous, free stockpiling alternative in the Bitcoin people group, and is one of the most, if not the most, well-regarded of the work area stockpiling applications out there. Electrum gets high stamps for its convenience and UI, which is constantly decent, yet the genuine reason it's the best Bitcoin wallet for work area is its wellbeing and unwavering quality. As with any workspace wallet that deserves respect, customers have the opportunity to check their private keys thanks to Electrum. Your private key is a long string of letters and numbers, and you need to keep it private as it gives you access to your Bitcoin. Numerous online wallets and online trades don't give you extreme control of your private key, including an additional layer of hazard. You need to both trust the counterparty is a decent entertainer and expectation its servers don't get hacked, as that could bargain the administration or your data.

Final Choice

If you do not plan to store your Bitcoin or altcoins for too long, you do not need the hardware wallets I mentioned in the first item. In this case, I think the best of the remaining four options is the Atomic Wallet. Because it has great community support rather than all the technological infrastructure and the number of coins/tokens it supports. Besides, you can get all the support you need about Atomic Wallet quickly and in detail through Telegram channels. As a result, aside from the hardware wallets, the best bitcoin and even the altcoin wallet on the market seems to be the Atomic Wallet in terms of all the features it has.

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

Groestlcoin EasyVanity Released

Groestlcoin EasyVanity is a Windows app is built from the ground-up in C# and makes it easier than ever before to create your very own bespoke Groestlcoin address(es), even whilst not connected to the internet! You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.
