Introduction

Bitcoins can be spent if one know the private key for a bitcoin address.
If one memorizes the private key in his mind,
it can be said that "Bitcoins are stored in his brain."
This concept is sometimes refered as a brainwallet.
Please refer Bitcoin wiki's article for details.

OfflineWallet.info provides a brainwallet with a nice UI.
It also supports altcoins and multiple languages.
OfflineWallet.info does not use external databases,
you can download it to your local machine to increase security.

Why Brainwallet?

All transactions are signed client side using JavaScript,
no secret key information is passed to external servers.

Many web wallet stores Bitcoins in their server,
there is a risk that the servers are cracked and all the funds stolen.
However this wallet does not send any secret key information to external servers.
So you can safely store your bitcoins as long as you choose a safe passphrase.

Hello guys.

I opened KUMA/MONA market in my exchange.
You can trade kumacoin with monacoin, Japanese most popular cryptocurrency.
https://monatr.jp/trade/kuma_mona?lang=en

If you do not have any monacoins (MONA), sell your bitcoin for monacoin first.

WARNING:
I have never supported PoS-type cryptocurrency, so there should be a bug.
If you feel something wrong with my exchange, please report it via E-mail or Twitter!

Please enjoy kumacoin!
