I really feel like I want to puke and I'm shaking all over my body and can barely type.
I was just checking my wallet on blockchain and noticed that all my bitcoins were transfered to another account!
From the Details it happened yesterday.
I had made a brainwallet which i tought noone could have guessed and never put my private-key somewhere.
Please is there anything I can do or at least to make me feel better? I just don't have a clue what to doaöäshefp9heWHFPAWHEFE
How can this really have happened??

As the acceptance increases, entropy will decrease and we will see more such cases.

There will be more and more brain wallets, so the chances will be higher that someone will stumble upon the same sentence.

There will be more and more brain wallets, so the chances will be higher that someone will stumble upon the same sentence. Hence why you either dont use them OR use extremely long sentences which you wont remember so its not a brainwallet anymore.

Sorry to hear man, brain wallets are not a good idea if you are going to use an easy password.

Yup. Not a good idea at all. You're going through so much trouble creating it and in the end you're using easy password - how messed up is this. ![Wink](https://bitcointalk.org/Smileys/default/wink.gif)

Sorry, there is nothing you can do. The mistake you made was thinking that nobody would or could guess your password. No brain wallet is safe. There are 6 billion people in the world. What are the chances of one of them using the same password? What are the chances your password being guessed by any of the thousands of computers that are making millions of guesses every second? Both of those possibilities are very high. Any password that can be memorized can be guessed easily or accidentally. OK, I realize that caution has to be used with brainwallets, but what you say is overstating the case. The 12 word mnemonics that have 128 bits of entropy generated by Electrum and others can be memorized, and so can be used as brainwallets. They can't be feasibly brute forced or guessed.

There are people that would have no problems memorizing 12 random words. Heck, there are a few people in the world that can memorize thousands of digits of pi. But, don't expect most people to be able to do that.

OK fine, but I just want to point out that you kind of stress me out a little when you say "any brainwallet you can memorize can be cracked" because it makes me doubt my understanding of cryptography (because it implies that the 12 word randomly generated mnemonics in wide use are not strong enough).

Well it's obviously false that any brainwallet you can memorize can be cracked, because theoretically one could memorize a private key. But you're not going to be remembering that in 6 months.

You and I have a very different idea of what the word "memorize" means.

Those 12 words are generally meant to be written down. There are very few people in the world who can memorize a completely random set of 12 unrelated words and recall them all in exact order a decade or two later if they haven't used the set for anything in the meantime. If you are capable of that, then you can use a passphrase generator that generates properly random sets of enough words, and then memorize it if you like. The vast majority of people who are trying to create brainwallets, are trying to come up with something out of their own head that they have enough of a connection to that they believe that they will remember it after a significant amount of time has passed. This is a VERY BAD idea.

This is a VERY BAD idea. *sigh* I'm not disputing that it's a bad idea. I just think it's possible to say "brainwallets are a bad idea for reasons X, Y, and Z, and here are examples of passphrases that would get cracked immediately and others that are considered safe (i.e., 12 randomly generated words following the electrum method)." I think most people have at least some intuition about what they are capable of memorizing, but very poor intuition for what makes a good, unfeasible to guess, private key.

It wont matter if he you can trace it, it can be mixed in easliy and not be traced also by trading it with litecoins, then he can sell lite coiins for cash
