this guy had 30 BTC stolen from his cold storage! he says he had his private key saved into his email draft with the seed written in casual order!
there should be 24!=6.204484e+23 possible combinations for those words!
how likely is that the hacker succeed in put the words in the correct order and steal the funds?
