the thing is, he didnt even have to walk away,... if you hold a giant amount of BTC like that you can just temporarily crash the market, and get back all the original bitcoins you sold and have tons of money left over... or be extra greedy and just get a ton more bitcoins. the whole thing seems so blatantly easy to do (on his part or anyone else who could potentially hold a majority of the bitcoins)

that way its not "stealing" because he has the chance to give all the original BTC back while still making bank all by making users wait a week or 2 weeks or 3 weeks.

if the site was really hacked it would have been immediately brought to everyones attention. at this point i think hes trying to cook the books and doctor log files or whatever. but imagine if everyone does get all their bitcoins back from him who file claims... if that is the case I think this is exactly what he did

or maybe het got scared about Bruce Wagner & the FBI coming to his door, and he was going to steal it all and walk away but decided "oh ill just make half as much money this way im still rich! time to make up a story"
