Title: brainwallet collision Post by: RoxxR on April 05, 2013, 05:25:13 PM Given that humans are pretty bad at making random passwords, I'm guessing brainwallet collisions are
bound to happen. Anyone knows or can estimate how often it happpens? Title: Re: brainwallet collision Post by: BlindMixerDR on April 05, 2013, 09:07:57 PM I think it already happened. There was a link where someone lost 5BTC in brainwallet. Better to use deterministic wallet with lots of entropy, and encrypt with a good passphrase.
Estimate of how often it happens depends on many things: 1. How long is the passphrase 2. How many people use brainwallets 3. How good are people at using unique passphrases and a mixutre of characters, numbers, symbols etc. Title: Re: brainwallet collision Post by: deadweasel on April 05, 2013, 09:18:09 PM I think it already happened.
