Reserved for Q&A:

Which one is better, a phone, or a hardware wallet?
Hardware wallet:
1. produced by ?
2. maybe presale and who knows the actual deliver time?
3. how about the failure rate?
4. expensive.

Phone:
1. produced by Google, Apple, Samsung, LG, Moto and so on.
2. sold millions of units everyday.
3. high industry standard.
4. cheap (some are even lower than $20).
5. great user experience.
6. best operating systems (Android, iOS).

Bither Cold Wallet is running on an offline phone, and has automatically backup function. That means, at least you can have two seperate hardware devices (ROM and SD card) keeping your wallet safe. If you want more backups, you can buy more SD cards, it's cheap and also follows the industry standard.

So, which one is better?  ;)

Cold & Hot Wallet Modes.

We can just wait until they make it open source in two weeks...

We will open source our project on github.com in two weeks.  :)

Yep! Can't wait to see what the backend looks like.

If you are going to open source the code in two weeks why not wait two week and launch with open source code?  To any user considering using the client, wait two weeks for the source code first.   

Thanks for your support, currently we are working hard on the next version of Bither, we will release it as soon as possible.  ;)

Thanks for your advice,  :)
Currently we are working hard on Bither 0.0.5, so we plan to open the source code after that, we will finish the work as soon as possible.

Looking forward to your new release and open source code.

Thanks, currently we are working hard on next version of Bither,  :)

Come on! Waiting for open source.

We will finish the new version and release the source ASAP,  :)

I don't really see how this makes a hardware wallet obsolete. A phone can always fail/brick/die/break/whatever. A hardware wallet never ever connects to the internet and never can. It will always go through a computer, the keys can be generated by it's seed and it's security is a lot better then some app on some phone (think of Trezor's pincode input). I would like to know what kind of steps you have taken to ensure security on the cold wallet phone (except disabling all communication).

I would prefer Trezor instead of Bither, but oh well, that is my personal opinion and subject to change. I do wish you all the best and good luck with this project!

In your opinion, a phone produced by Google, Apple, Samsung, LG, Moto is fail/brick/die/break? Then why billions of people using their sollutions every day?
The benefits of using a phone as a hardware wallet are:
1. Industry Standard;
2. Cheap (some android phones are even lower than $30);
3. Great user experience;

Thanks for your advice, and we will work hard to help people saving and using bitcoins easier and cheaper.
 :)

They will eventually. Most phone start to wear down after 1 year and a lot of phones stop working after 2-3 years. Also you skipped my security question, please answer it. ;)

The most important security for normal person is keeping the device offline. You can have ten diffenent locks on your door, does that make you feeling safer?
If you can prove that the expensive Trezor has higher industry standard than popular phones, then you win.  ;D

This seems interesting. I'll defenetly give this a try myself after the github release.

Exactly! You can have 10 locks on a device that has the ability to connect and it eventually will connect. Bither lock can't protect you. Only the device that can't leak keys by design can keep private keys inside.
You are right that people trust their phones with some personal data. The security of a phone is good enough to store your FB password, but I won't trust it with my live savings.
How does your app get in the phone if the phone never connects to anything? How do you update your app? If the phone was infected before your app was installed, how can you be sure that it is not communicating?
Security expert can verify simple single purpose communication protocol of Trezor and its code base. No single person can verify Anroid.

Basic problem is that a phone can die from one second to the next. I had it. Woke up with phone alarm. Went to bus station and wanted to look what time it is. No reaction at all. Mainboard died and i had to wait 2 weeks to get the phone with text: we where not able to restore the data. It was a Note 2 from Samsung. So i would never trust a phone! I had some bitcoins in my phonewallet but i had a complete backup of everything. So no loss.

All electronics can die without warning.   You should always have backup/seed for any device.

Who use second phone??

dont see any differences between this app or any other wallet app..

Thanks for your support.
We are working hard on the new version, and we will release the source ASAP.  :)

Bither Cold has automatically backup strategies, and you can easily backup your cold private keys on as many SD Cards as you want.
Also Bither Cold Wallet is easy to clone between your backup phones.
We will also provide improved functions for backup and recovery in the future version.

Thank you. :)

For 5 years has my Moto Milestone been working properly so far.

You can try our product to see the difference, thanks,  ;)

You are right.
Backup is very important. Currently Bither Cold provides automatically backup strategies, and we will improve this function in the future version.

Thanks for your advice, it's very helpful. :)

Yes, today,  :)

I really like your implementation of hot and cold mode. Will try when I clean up my old phone.

My primary worry is whether it contains malicious code, and secondly whether is has major bugs. I do not have the skills to verify the code and compile the apk myself, so I will only test on a clean phone and test with small change. I do appreciate your work and thanks for taking time to develop an open source android wallet.

As for cold mode, the only thing you should worry about is the private key generating part. If it's really an offline randomly generated private key and you never connect your phone to the internet, your private key would be completely safe.

Bither as an open source project, more and more people will contribute to it. Major bugs will be found and fixed soon if they exist. However they will never put your private keys on cold phone in danger, because the private keys are separated from the outer environment physically.

Thanks for your support.
We will work hard to help people using and saving bitcoins easier and safer,  :)

Now the source code is open, this will definitely help your team getting more trust from users.

Just curious, what's the story behind the name "bither"? It always reminds me of "bitcher" or "birther", which are not very good for your brand image  ;)

Our website is Bither.net, it comes from Bitcoin and Ethernet.
We consider Bitcoin and Ethernet as the most important inventions that make the world better. To show our honor to them we combined the two words and named our project Bither.

Thanks for your support, :)

I see, now I know why its called 比太 in Chinese. Uhha.

http://www.amazon.com/gp/aw/d/B00GFTI0SO

This $20 phone is a perfect match to your app.

Only downside is the OS is a bit old --did you test it on android 2.3?

 ;)

Bither is running ok with Android 2.3, and this $20 phone looks nice, :)

If the camera support autofocus, that will be easier to scan the QR-Code.

Thanks for your support, :)

Confirmed.
3 years old xiaomi phone as Cold Wallet, in flight mode one full charge can last one week at least.

Yeah,  ;)

yeah I rather put my wallet in a safe or external hard drive, you dont know who you can trust these days.  Im sure these type of services wont work especially with all the stuff that happen with people losing coins. 
Since there is no FDA I wont let any company hold my coins.

Bought one, installed a few wallet apps including Bither, put it in Airplane mode, this thing lasted 5~6 weeks before needing a recharge.  8)

Bither Wallet is decentralized based on Bitcoin P2P network, nobody hold your coins except you. :)
You can check our source code for more details.

Thanks.

wow, 5-6 weeks? so amazing......  ;D

Any chance of getting deterministic wallets? This is what everyone is waiting on in the "mobile device wallet" market right now.

Currently, we are working hard on other functions of Bither Wallet.
Maybe in later version we will consider to support deterministic wallet.

Thanks for your support. :)

i hope it does not cause problems for my cellphone...

Bither is an open source project, and it is decentralized based on Bitcoin P2P network.
I think your cellphone will be safe.  ;D

Thanks for your support.

I love the new version.

Thanks for your support,  ;D

It seems very interesting.To use?

You can try bither with some mBTCs, and also you can fork our source code on github.com .
Any advice will be very helpful.

Bither iOS v1.0.0 released on App Store.

https://i.imgur.com/BHm2788.jpg

Bither iOS demonstration video:
http://youtu.be/Q1DSrc7qkrs (http://youtu.be/Q1DSrc7qkrs)

Hello there!

I saw the video yesterday and really liked it, I have an iPhone without Bither network for cold and iPad for online Bither.

I wish I could incorporate my wallet private key paper in cold Bither.
Important to have the private keys generated Bither to keep as security if one day something happens to the iPhone (loss, theft, breakage, etc.).

Otherwise it's fantastic, congratulations!

Thanks for your support  :D

We will provide advanced options for private key management in next version, and use can safely see the private keys after inputing password.

Thanks again.

What does this offer over a super secure mobile wallet such as mycelium?

Bither originally designed for Cold and Hot modes. Because Bither Cold Wallet runs on your backup phone (keep the phone offline), hackers, virus can not steal your bitoins.
On you daily phone (online), you can run Bither Hot Wallet and save small amount of bitcoins for daily use, and monitor your Bither Cold Wallet's bitcoin assets.
 ;)

This project is looking pretty cool.

I am pretty sure that a lot of people will have old phones they can use!

Thanks for your support,  ;D

Bither v0.0.8 released on Google Play.

1. Secure Keyboard.
https://i.imgur.com/H7H0xnj.jpg

2. Long press the lock icon for more advanced options.
https://i.imgur.com/TgbNYjl.jpg

I have a few friends who would use if they could enter the private keys in the cold wallet.

For when? I want to use it safely!

Encouragement and congratulations, great job!

Thanks for your support!
We have supported entering private keys on Bither Android v0.0.8, and will support the same function on Bither iOS v1.0.1 .
Bither iOS v1.0.1 will publish to App Store in next week (plus Apple's review time), and after that we will open source our ios code on github.
Also, we only support the compressed version of private key. You cannot enter the old uncompressed version.

:)

Lateral observation --I happen to do that from time to time given my use of an iPad 1.

iOS 7 requirement leaves some users out.

I really don't know if that's either promoted by software development tools, or caused by lack of consideration on the side of developers. I presume all functionality could be achieved without demanding for such high OS version requirement.

Anyhow, that's why there are several systems to try out, with this one, for now, I must pass.

Sorry for the iOS version limitation. Because iOS 7 had so many new features on UI developing, we decided not to support iOS versions <=6 at the beginning.

Also, we don't suggest users use iPad 1 for Bither Wallet, because the iPad 1 doesn't have camera which means you can scan QR-Code with it.

Sorry for the inconvinience, maybe in later versions of Bither, we will try to support lower iOS versions.

Thanks for your advice.  :D

Sincerely,

Wen Hao (Bither Team)

Fantastic! look forward to the new version :-)

Thanks  :D

Add two documents:
1. Build Bither Android (https://github.com/bither/bither-android/wiki/bulid-bither-android)
2. QR Codes content format (https://github.com/bither/bither-android/wiki/QR-Codes-content-format)

Very Nice.

Where does the hot wallet get the blockchain information to display balances. Does it download the blockchain or does it use a back-end server?

Regards,
ffe

Bither Hot Wallet are based on Bitcoin P2P network, and will sync the related transactions with the Bitcoin blockchain.
Thanks for asking.

:D

yes but i thinkt thats all same llike other thing . always rrelation with blockchain.

we should related to Bitcoin decentralized blockchain, not a centralized website.  ;)

Hi guys!!

How about the new version will IOs? When do you throw?

Bither iOS v1.0.1 are still waiting for Apple's review......

Great!!!

This new version include import-export private keys?

Yes, the new version has advanced private key options. With long press on the lock icon, you can find more details.
:)

Bitheri : the first Bitcoin library implemented with Objective-C

Also, we released the souce code of bither-ios:

https://i.imgur.com/WA4hmCY.jpg

Congratulations guys !!!

I downloaded the new version of iOS and is perfect, thanks for incorporating the export and import of private key, now I'm using Bither.

In gratitude I have donated 0.1, wish it had been more, you are doing a brilliant job.

I take the opportunity to ask, when a signed transaction will your servers or do you use blockchain? (https://blockchain.info/pushtx).

Thank you very much for your great work!

I scanned the cold TX purse and not get the raw tx if your not a format.

I want to ask a favor if possible that you can get the raw tx as an option if we want to send from our purse or the https://blockchain.info/pushtx own

The reason is if some unlikely possibility, Bither hot wallet could not connect to the internet and can´t send tx

Thank you !!

I have seen that when sending a transaction from a wallet cold, the fee is always 0 and takes too long to confirm. Can you make the configuration work on commission wallet cold?

Best regards!

This situation is because we want you pay as less transaction fee as possible. In version 1.0.0, this logic is not good enough. In some situation it will cause a zero fee transaction being sent. This problem is solved in version 1.0.1 which can be downloaded from app store now.

Your transaction will be confirmed in the future eventually. We are sorry for your concern. Thank you for your feedback.

Dear Varmetric,

Special thanks to you, and also thanks for your donation. You are so kind to our team. :)

Bither is decentralized and based on Bitcoin P2P network. Bither doesn't depend on our servers or blockchain.info's, when you send bitcoins, you don't need to depend on any thrid party's servers, and Bither will publish the signed transaction directly to Bitcoin network.

Bither-ios is based on Bitheri (a Bitcoin library implemented with Objective-C by us), and the source codes of bither-ios and bitheri are both on github:
https://github.com/bither/bitheri
https://github.com/bither/bither-ios

Thanks.

Sincerely,

Currently, Bither is designed not to rely on any centralized service, so it doesn't use any services provided by blockchain.info.
Maybe in later version, we may consider to support exporting the formated raw transaction.

Thanks for asking  :)

In some situation, there may be zero fee transactions created by Bither.
We may change this setting in next version.

Sorry for the inconvinience, we are working on next version to make Bither better.

Thanks again for your kindly advice.

Sincerely!

Bither iOS v1.0.1 released on App Store.

https://i.imgur.com/miTNIz4.jpg

It would be fantastic, very useful and does not take much work to the raw crude. Definitely gives confidence and safely.

Congratulations, few recommendations can give!

I was struck that in your source code https://github.com/bither/bither-ios/blob/master/bither-ios/Api/BitherEngine.m config apparently a call to your server:
             userNetworkEngine = [[MKNetworkEngine alloc] initWithHostName: @ "bu.getcai.com" customHeaderFields: headerFields];
             statsNetworkEngine = [[MKNetworkEngine alloc] initWithHostName: @ "bs.getcai.com" customHeaderFields: headerFields];
             bitcoinNetworkEngine = [[MKNetworkEngine alloc] initWithHostName: @ "b.getcai.com" customHeaderFields: headerFields];

Being getcai.com your servers, I was curious to know if Bither could always work though your servers were down.

In the API I have not seen calls to your server, it may be true that work Bither networked bitcoin natively.

Could you give us a clue that these calls are?

Greetings!

The centralized services of b*.getcai.com are used for the following purposes:
1. Exchanges data (prices, k-line and so on).
2. Currency rates (USD, CNY, and may support more currency later).
3. Avatars' support (Currently only bither-android suports QR-Code with user defined avatar).
4. History transactions downloading API (When you monitor or remonitor the cold wallet, Bither will retrieve the history transactions of that Bitcoin address from b*.getcai.com, because we cannot efficiently get the histroy data from Bitcoin network. If we retrieve the history data from Bitcoin network, may cause the whole blockchain data downloading, mobile phone cannot support that much data space and network usage).

So, that means when our centralized services were down, you cannot get the current exchange rate or price info, you cannot retrieve the history transactions at that moment.
But the normal Bitcoin functions will still work well, you can send or recieve bitcoins, you will still be noticed when new transactions are coming.

Because we were working so hard on coding, we did not provide enough docments for users to understand more about our solution. Until now, we only finished two docs (you can find them on bither-android repo's wiki), one is "How to build bither-android?", the other is "Descriptions of QR-Code Format." .
In the next week, we will publish a new document about api information. After that, I will notice you ASAP, and you can take a look at that doc (and related source code) for more details.

Thanks again for your question. That helps us a lot. ;D

Best Wishes!

It is right and it makes perfect sense.

Thanks for the clarification !!

Varmetric, thank you very much. We had found that in Bither iOS v1.0.1, there were still possible to send bitcoins with zero transaction fee.
We will fix this issue in today, and publish v1.0.2 ASAP.

Thanks again. It's very nice of you.
:)

One suggestion geek plan, imagine a cold wallet with multifirm, would be perfect for companies and funds that do not depend on a single employee or person. This addition of multifirm would be a perfect solution for corporations, partners, etc.

What do think? Do you dare to do it?

Can i loading this wallet of my  iPhone 5s?? Can any please Tell me? thanks

We're busy developing Bither now. We currently don't have time to support other kinds of coins.

The source code of Bither is on Github. Anyone who's interested can edit the code and make their own wallet.

By the word "multifirm", do you mean multi signature addresses? We haven't considered a use case like you said.
Bither is mainly focused on normal people's personal usage of bitcoin. And we're making some stability improvements now.
Maybe we'll think about this later when we finish our current tasks.

Not sure what you mean by "loading". You can install Bither on an iPhone 5s.

I have talked to several companies that have to guard bitcoin bitcoin Bither of their customers and they love it!

For them it is important to multisignatures no person may have access to funds. If Bither has multifirm avatarbtc.es and other companies like it used because it is the best solution right now there to guard bitcoin safely.  ;D

After we finish our current plans, we may consider MultiSig seriously.
Thanks for your advice,  :D

Thank you very much !!

Now I have wanted to see:-)

Ok something is really weird with Bither,

So I have A private Key - Un-Encrypted - I also have a public Key obviously.

I have 2 phones.



Online = Hot << tried Scanning Watch only address bither Cold, I aimed the the camera on the Public QR code, Nothing happens, So I then thought.. AHHHH! maybe it only recognizes Bither cold wallet addresses, Then When I scan the QR code from the bither in the Hot wallet as a watch only wallet it will work. WELL GUESS WHAT? Check below

Offline = Cold << So I decided to try scan my private QR Code  from my offline COLD phone Bither, and again it doesn't scan, I can feel a vibration when it detects the QR Code, but it does absolutely nothing, just stays there like it still wants to scan something, the same thing that it does when I try to scan a watch address in the hot wallet..

-------------------------------

I dont get this, does bither only accept special QR codes or something??? I tried to scan the exact same address in Mycelium, within 2 seconds it scans with no problem at all, it also scans Bip38 and many other encryptions. So far I have not scanned a single address in Hot or cold Bither

Hello, I think I can answer myself. When I wanted to incorporate my purse Bither cold paper was not able to read the QR with the private address. It does nothing, only vibrates.

I discovered when entering the private address by hand, which is my private address uncompressed Bither is compressed only able to import private keys.

My solution was to import paper purse blockchain.info and generate a cool wallet in the smartphone and import the compressed private key and send the funds from blockchain.info:
http://offlinebitcoins.com/

IMPORTANT: Make cold backup in case your smartphone wallet breaks or the data is lost.

For now Bither Hot can only scan and monitor the Bither Cold's watch only QR Codes, not the address QR Code or any kind of private key back up QR Code. Bither Hot needs the public key provided to get all the related transactions from bitcoin networks. Only providing the address is not enough and providing the private key is unsafe. So we use our own QR Code content format and only contain the public key in it to communicate between the hot and the cold.

Here is the link to our QR Code content format
https://github.com/bither/bither-android/wiki/QR-Codes-content-format (https://github.com/bither/bither-android/wiki/QR-Codes-content-format)

And we plan to support importing private keys in BIP38 format in the future

Why not just a settings menu where you can add any exchange using their API. Just input the buy/sell/withdraw/deposit commands for the exchange you want to use.

 This is really confusing. I have a cold storage already made , I do not want to use a new one. Are you saying that I HAVE to create a new one and I cannot import a current cold storage? It has Import Private Key inside Cold wallet, When I show the private key QR code UN-Encrypted it does not detect it. I don't get it.


If there is a way I can please tell me the steps I need to do ? If there is no way I can import current Cold storage let me know thanks.

I have the Public Key- also known as Address

I have the Private Key for this Public Address key

I have the Bip38 version of the private key.

I have ALL relevant information to access this wallet, how can I use Bither in this circumstance without creating a fresh address.

You can import plain text private keys into Bither Cold (same format as bitcoin-qt dump private key command). Bither does not support BIP38 QR Code right now. And we will support it in the future.

Dear gtraah,

We will support BIP38 ASAP.
Also, we will support uncompressed Private Keys ASAP.

Sorry for the inconvinience, and special thanks for your advices  ;)

Sincerely,

Wen Hao

Maybe we will consider your suggestion in the future version of Bither.
Thanks a lot :D

Special thanks to Varmetric. We will support uncompressed private keys (old version) in the future.
Also we will support BIP38 ASAP.

You have no access to vault. If Xapo goes, your BTC goes. Currently, it is better to use Bither or other wallets which support cold storage .

   ~~MZ~~

Sorry i posted here i clicked on a wrong link , the Wallet from here looks good but the design could be better.

You have access to the BTC , because you have the Privat Keys, you need to ask and you get them (Encrypted)

Bither iOS v1.3.1 released with HDM.

https://i.imgur.com/wRFwpR6.jpg

Hello,

I am fascinated to see Bither evolve and progress!

Is this signature format a Bither proprietary format, or a format compatible with other Bitcoin clients (which) like Electrum , Armory, ...?
(i.e. can Bither verify signature strings from client ABCXYZ, or vice versa?)

Is there any plan to incorporate "hidden private key" feature for "plausible deniability" to "Bither" wallet (as detailed in the OP of "https://bitcointalk.org/index.php?topic=361386.0")?

This would be a very useful feature to protect against violent physical theft of bitcoins, and I think up to now it is not implemented in any wallet software yet.

Generally, everybody is concerned about good technical cryptographic protection (for very good reason of course!!). But we should also be concerned about PHYSICAL theft: What if someone points a gun at me to hand over my private keys?! --> There is a very simple and effective solution of how a user can give his private key to a thief while still keeping his life savings.

This scheme could be implemented in both BitherCold and BitherHot (in the latter case for the "hot private keys").

I am not going to repeat how it works exactly here, because I have detailed it in the link above, so please just refer to that post to understand the motivation and the solution, but in short, the basic principle goes like this:

  HiddenPrivateKey=sha256(NormalPrivateKey||MoreOrLessSimplePassword)

• with "||" denoting simple "concatenation",
• with "NormalPrivateKey" being the private key as it is stored in the Wallet software today, and
• with "HiddenPrivateKey" being a temporary key calculated upon the user's selection of the NormalPrivateKey's Address and typing of a password. This hidden key should only reside in RAM memory temporarily while the user makes a transaction, and never leave any traces in flash memory. Obviously, the user should also not store the address of this hidden key in his list of watch-only-addresses, because this would render it less plausible to deny possession of that key.

  Clearly, if someone steals the phone and knows the PIN, he can access the NormalPrivateKey but has no idea that another (or several other) "HiddenPrivateKeys" even exist.

The method is good for BitherCold for evident reasons (theft protection), but also for BitherHot if I want to take some Bitcoins with me on a journey but don't want to loose them all if I move with my smartphone into an unsecure neighborhood and get robbed...

Hello,

Me too! They are makimg it better!

I was successful in verifying, so I think it is compatible with other clients.

   -MZ

Which "other client" did you use? I think Electrum and Armory use different formats...

Dear crazyearner,

There are Address Tag(Label) function on Bither iOS/Android. So you can add tags to your addresses. But currently, desktop version does not support this, we may add this feature in future release.
Also, we may provide more functions on addresses sort order.

Thanks for your feedback.

We may continually work on improving vanity gen. Thanks again :)

I've just installed the android version and it looks pretty good, but I don't like that I have to use the build-in keyboard. I'm extremely used to SwiftKey and creating a good password was hard because all the special characters are two taps away (and I use a lot of them in combination with letters). SwiftKey doesn't have this issue.

EDIT: Also this doesn't look right. The "+"-button overlaps the text of the exchange the price is from.

Any developments for updates on Windows desktop wallet. Do you guys do other crypto at all? would love to see something like this made for other cryptos to make a multi wallet version in the future and dominate where others fail :)

Have you considered asking mods or whoever to move this to the alternative client subforum? I think it belongs there more than here.

Would be a good idea for it to go into that section but unknown if mods will move it into their. Sent pm to gmaxwell see what the response is if  good enough to support being in that section or weather or not needs to stay in project development. Al lthat is really needed on this  client is active mods and admins for support and updates but no doubt am sure working in background.

This Wallet seems to be interesting but this is new one. After sometime, it may comes popular !! :)

Bither Android v1.3.9 released, iOS version released too  :D

Dear Mitchełł,

There are so many third parties' keyboards/input methods on Android, and some of them are even cloud services. So for security reason, we decide to develop our own keyboard/input method, and not to rely on users' environment.

About the "+" button, it does overlap some part of the screen, and we may consider to improve this or hide this button in some circumstances in future release.

Thanks for your feedbak  :)

We may consider to working on improving our desktop version as possible as we can, and also we may think about other cryptos too.

Thanks  :D

Thanks for your support  ;)

I've been using this wallet for ios and its great. the only thing i recommend adding however is the ability to remove a selected address.

So what is the security on android compared to Mycelium? Is there HD wallet support? What makes it special?

any plans on adding a sweep key feature?

Would be really cool to see this wallet go all out into multi cryptos and add in other or have feature to add in and compile or drop files in to support new coins.

https://i.imgur.com/m1ZOKhv.jpg

I don't really see how this makes a hardware wallet obsolete. A phone can always fail/brick/die/break/whatever. A hardware wallet never ever connects to the internet and never can. It will always go through a computer, the keys can be generated by it's seed and it's security is a lot better then some app on some phone (think of Trezor's pincode input). I would like to know what kind of steps you have taken to ensure security on the cold wallet phone (except disabling all communication).

I would prefer Trezor instead of Bither, but oh well, that is my personal opinion and subject to change. I do wish you all the best and good luck with this project!

The wallet looks very nice and has good functionality.
I also like that it is available for all the most common platforms.
You should definitely continue to work on it!

But I don't think it wins over hardware wallets in terms of cold storage.
You comparison looks biased.

The temptation to go online with the cold storage phone at some point in time is just too big.
And the price and availability is no argument anymore now that you could get a ledger hardware wallet for 15 Euros (incl. shipping) within a few days.
(I'm not affiliated with Ledger Wallet)

And what about size and battery?
Smart phones are bigger and heavier than hardware wallets and you have to charge them every day (especially if you use an old phone were the battery is not that good anymore)
And you can be sure the battery is empty just when you want to do that payment. ;-)

Any news for Windows update yet? seen you making improvements to it to release 1.4 on most other devices but Windows lacking. Why hate so much for windows lol.

For real BTC users this can be good news. Most important - if in the wallet you can send/receive bitcoins.  ;D

I have installet Bither and it looks nice. Is there any complete manual/documentation somewhere which I could read so I can know what all the functions and settings are?

It would be great to see, but I'm not sure it's even in development at this point. Maybe we should start our own project for this? ;)

2. Improve Performance.

Please have an update in Windows and android wallet to support custom fee setting as now set with normal fee payments sent over to exchanges and stuff are saying low fee included will take long time to confirm.

Hi, I installed Bither on two of my iPhones. I don't see any buttons to choose between Cold and Hot modes. I generated an HD wallet but I can't see how to generate QR codes for the the Watch-only phone to read. I can generate QR codes for the seed but that is not the same.

seems interesting, i will give a try

On the cold phone, you should make the phone offline, and then switch to the cold mode after you newly installed Bither. You can find the switch option in the option page if you have not create addresses.

Then you can follow the steps from these documents to try the cold/hot wallet functions : https://github.com/bither/bither-doc

Thanks  :D

Bither Android v1.6.1 and iOS v1.6.2 released with:
1. Adjust the transaction fee option;
2. Add advertise;

Having problems sending coin from wallet to exchange it shows transaction on blockchain never confirms even with low or high fee and when I have re indexed block chain the coin is back in my account balance. This is using Windows version of wallet. So seems can not send coins from wallet been like this for last 2 days. Sends transaction shows in wallet. Go to exchange shows it their in unconfirmed awaiting to process and never processes and gets confirmed. Whats going on?

Also on blockchain getting following error with transaction too.

Transaction rejected by our node. Reason: Transaction was previously accepted but has been pruned from our database.

UPDATE 2017.05.24
New mobile/desktop version released with higher fee options.

How to recover HD account from seed in Bither? And what is "HDM Recovery"?

Import --> From HD Account Phrase.


HDM = HD + Multisig.

- 2/3 Multisig;
- 3 keys (Cold, Hot, Server) all based on HD;
- XRandom seeds for HD;
- Access server API via BitID technology;
- HD's convenience + Multisig's safety;
- Easy to backup (only need HDM Cold seed);
- Bither's Cold/Hot modes with XRandom are the best mates with HDM;-TXs are signed based on RFC6979 to ensure security;
- Parent pub keys of each HD chain won’t leave its own device (Cold, Hot, Server). No ways to leak;
- BIP16, BIP32, BIP39, BIP44, BitID, RFC6979, XRandom, Bither (Cold/Hot)

In iOS, Advanced Options -> Import Private Key -> HD account passphrase.

I couldn't find 'Import (from) HD account seed/paraphrase' in 'Advanced Options' and that's why, I was confused.


Thanks!

Bither only support one HD account, so if you already have one, there will be no import HD option.

Currently we remove the HDM options, the HDM recovery option is only used for old HDM users, and we may close this option too in the future.

Hello Dev, I have imported my seed of hardware device to Bither, then I have checked that it reports I hav a few getable BCH. I have installed Bitpie too and it is mandatory to specify a bitpie bch address for withdraw. Once I enter my bch address (generated via BitPie) and try to create transaction first it displays amount and transfer fee, then upon clicking OK it says -25Missing inputs under yellow bar.

Do you have any ideas to troubleshoot this issue?

That means you have already claimed BCH.

cant see my transacion from mobile bither wallet in blockchain.info or mempool (((( only here https://chain.so/tx/BTC/533657479453a64805e9894189a437096e796b39646664afc2a6fae1cfdc416f

what shall I do?

Great job! I see you are doing really wel! When do you enter the exchanges?  :)

Strong project! The competition on the market of wallets should lead to strong long term solutions. Maybe bither will become a very important wallet one day?

I wish I could incorporate my wallet private key paper in cold Bither.
Important to have the private keys generated Bither to keep as security if one day something happens to the iPhone (loss, theft, breakage, etc.).

Otherwise it's fantastic, congratulations!

This wallet has been around since 2014 and it supports most of the forks. It does seem a bit shifty though and I am worried about using it. Does anyone use this on a daily basis? Do they have any problems getting coins in and out of it? I like Coinomi's features but they don't support all the forks.

Can I use this to generate a bitcoin diamond address to receive bitcoin diamond? It is bitpie, right? Bitpie is open-source?

I am trying to recover my trezor seed using the Bither wallet.  I had multiple accounts on my trezor under the same seed.  I was able to recover my first account with no issues.  But I'm not able to access my other accounts.  Does Bither support multiple accounts?

will be there new version will IOs? When do you throw?

Is the Bitpie exchange secure/decentralized? Can I just leave my coins there, or should I move them to bitpie?

Bither v1.8.3 supports SegWit!

Bither v1.8.6 released:
Tuning the performance of importing private keys and reload transaction data.

A good application, smoothly used in various Android devices and easy to use. Just waiting for the airdrop distribution. Hopefully the price will improve even better.  :o

About one week ago, i found a project who use the same name of your company. It's called Bither Platform (https://bitherplatform.io/). The campany lunched its ANN thread (https://bitcointalk.org/index.php?topic=5109921.0) here in the forum since February 14, 2019, when the website has been created since second quarter of 2018 (according to the roadmap displayed in the ANN).
I didn't think that it was intended to pick this name for their platform, so i just pointed it out in their main thread:
One week passed and no one answered, this is why am posting about it here.

No one seems to bother trying to answer here either. 

Can not change the tx fee(default 0.0001BTC) with cold wallet(on hot wallet) to send btc? >:(

Hi, dear bither user, you are able to modify the default tx fee in Bither Wallet( hot mode).

Go to Setting- Default Transaction Fee, you will find it as shown in the pic below:

Thank you very much,find it.

But I suggest change this Setting to the fee box for easy changing it.

Bither Android/iOS 1.8.8 released
Bither Desktop 1.4.7 released
1. Improve the perfomance on reloading transaction data and importing private keys or HD seed.
2. Fix Bugs.

Thanks for your advice, we may add that in the future release. :)

Hello, I downloaded the Bither desktop wallet, created an account and transferred some coins to the account, but the coins transferred is not displaying in the account balance, and I can not also access the account created on the Bither wallet client, How can I recover my password? I seem to have lost my current password, what can be done to recover password to access my wallet?

Hi dear Bitpie user,
First, you don't need to worry about your asset security. 
The reason why can't see the balance is your Bither has not synchronized the blocks data.

Solution1:
Please go to "More"->"Blocks", and wait, until the syncing over. See the below pic:

Solution 2：
You never meet the above problem in Bitpie. Bitpie Wallet is a new generation of wallet developed by us following bither. It is multi-chain, much easier than Bither to use and has exchange module.  We strongly recommend you to have a try. (Download: https://bitpie.com/)
You are free to create a new account OR import seeds/ private keys into Bitpie Wallet.

If you still can't solve the problem. Our admin is availble on telegram: https://t.me/BitpieInternational. You can provide more details(like screenshots) on telegram to him for assisting you solving the problem.

P.S. It's suggested to use Bither android version rather than the desktop one, since the desktop version update is lagging behind the android one. We just released a new version v1.8.6; it was tuned for the performance of importing private keys and reloading transaction data. Please ensure you have updated to the newest version (download: https://bither.net/).
