First, a minor thing: I noticed that with my optional keyboard [ TouchPal ] it remembered and suggested one word after another of the 12 words I had entered previously. The input should switch to a simple keyboard without any suggestions/predictive features.

Preferences / Advance Options, should be Advance>d< Options.

Then I have a problem understanding usage:

I generate a mnemonic phrase which should help me recover my keys. Bither generates word1-word2-.-.-word12 separated using dashes. Most other programs use spaces for the phrase. This is confusing at the time of recovery. Then I reinstalled Bither (now there's no wallet in it) to simulate phone loss and tried to recover my wallet with the phrase created earlier. I Assume it should be at Advance;) Options and try HDM recover, but it's not there since I havent created a wallet yet. So where should I enter my passphrase to recover my key sequence? Tried Import Private Key from text (but think to myself: it isn't a key it's a wallet!) still try and it doesn't work. What's the sequence to recover a wallet from the written mnemonic word sequence?

I hope I can understand it before I commit to it. Thank you for such nice software!

How exactly are the cold storage keys encrypted? What does "Check private keys" do?

I would only trust bigger amounts to a cold wallet if I knew how the keys are treated and if I could export my private keys.

I found out how to import private keys into Bither, but I don't see a possibility to sweep private keys (e.g. emptying it by transferring its btc to a different address). Especially in dealing with paper wallets, sweeping a private key is the safer option.

Users who are familiar with cold/hot wallet solutions will have no issues using this wallet. Users who are new to the concept might need a bit of explanation. I suggest to add something like the following to the very first screen where you make the initial mode selection:

If you want to use Bither as a simple wallet, choose hot mode. To use Bither in hot/cold mode, you need two separate iOS devices with the device that holds your savings running in cold mode. The choice you make here is final for this device.

I just discovered the iOS version of Bither. Hooray! Finally a cold/hot wallet solution for iOS. Thanks for making it!

Bither shows CNY and USD. International users will probably also expect EUR, GBP, CAD and a few more currencies to select from.

热钱包是ANDROID手机，冷钱包是IOS。获取BTG时，用冷钱包签名BTG发送交易时，扫描完成后直接退出，无任何提示！原以为需要升级冷钱包，把冷钱包里的面私钥全部作废，删除冷钱包，然后联网重新安装冷钱包，又重新逐笔导入新的私钥，他妈的折腾了一个小时。重新在热钱包获取BTG，冷钱包扫描完交易后还是直接退出！！！------------------------------------------------------------------------------ 比太包钱包究竟在搞什么？！难道不知道用户用你的钱包很大程度上是看中冷、热存储功能吗？连一个领取BTG的功能都做不完善，还让用户怎么放心用！而且最可气的是发送BTG地址只能发到比特派钱包地址，强迫用户使用比特派钱包，增加用户的转账成本，我看你们也是快了！反正我以后是不会用了，去你妈的！

Bither crashed after receiving bitcoins

Steps to reproduce

Open new installation of Bither. Add HD Account Copy Address Send bitcoins to Address

Result - full system freeze, Bither does not start anymore. Wallet lost.

Hi, I didn´t forget my password but when I want to transfer Bitcoin Bither says "wrong password". I can use the password when opening "Export" e.g. but when I want to transfer it says worng password. What can I do? I am 100% sure it is my password especially it works at other situations.

I believe I don't have access to my private keys in Bither. I would expect to be able to export individual private keys, maybe not in clear text, but in BIP38 encrypted form.

已经多次实验：卸载比太（卸载/删除app），重新安装，关闭网络，打开飞行模式（手机里也没插卡），重新打开比太钱包。

在选择冷热钱包的地方一闪而过，不给我选择的机会。然后就进入了热钱包模式。 热钱包模式下面，进入设置，也没有网上经常出现的“切换至冷钱包“的选项。

iPhone7 , iOS 14.3 好像不能降级了。 在线等，挺急的。

From testing I have several cold wallet addresses in Bither-iOS that I now want to delete or hide because I will never use them again. How can I do this?

bither ios client, sync blocks very slow， is there any way that I can speed this process?

Another question, I using HD account to receive transactions, but every time I send transactions to HD account, I have to reset the transation data in the settings then I can get my balances update. It kind of annoying.

I am running bitcoin full node on my PC, but there is no way to select a synchronous node in Bither, I want to use my full node to speed up the synchronization

我在新电脑上构建 Xcode 12.3 构建时失败，怀疑与我本地的 oepnssl 构建方式有关？

Terminal 在 Open using Rosetta 方式打开，安装 homebrew 后安装的 openssl

I noticed you don't currently have a way for users to buy Bitcoin in bither with fiat currencies (USD, EUR, GBP etc.) I'm Thijs Maas from Onramper.com, where we've made a widget that can be integrate to instantly integrate multiple fiat gateways in once. Perhaps we can help out. With our widget you would also be able to set a commission per transaction to start earning on every fiat-to-bitcoin transaction. Let me know if this sounds interesting!
