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?  

[bithernet]

Cold & Hot Wallet Modes.

[bithernet]

Bither Cold Wallet
Features:
1. Cold wallet running on offline mode.
2. Private keys are protected by digital password.
3. Realtime monitoring the network status (Wifi, 3G, BlueTooth).
4. Security check for private keys.
5. Sign the hot wallet's unsigned transactions.
6. Automatically backup and recovery.
7. Easy to clone.

[bithernet]

Bither Hot Wallet
Features:
1. Hot wallet running on online mode.
2. You can easily monitor your Bitcoin savings with Watch Only mode.
3. You can prepare unsigned transaction for Watch Only address.
4. Hot wallet also supports private keys, you can save some poket money in this kind of addresses.
5. Decentralized and P2P (peer to peer) Bitcoin wallet, no registration or login needed.
6. Realtime price of major Bitcoin Exchanges.
7. System notifaction for new transactions.




Easy to communicate between Bither Cold and Hot Wallet.
The only thing you need to do is to scan the QR code.

I shiver at the thought that someone may actually put their life's savings into Bither. A wallet which pops up out of nowhere and says "Hey, check out our slick app design. You can trust this wallet, cause it looks hip. Forget the source code which we never showed. Hey, it's on Google Play, so it's legit."
I'M GRIPPED BY DITHER AT THE THOUGHT OF USING BITHER.

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

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

[DeathAndTaxes]

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.

[bitcool]

Looking forward to your new release and open source code.

[bithernet]

Looking forward to your new release and open source code.

[zhouqi_cn]

Come on! Waiting for open source.

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. 

[mailmansDOG]

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