Killed by the 90% of the stupid day-trading sheeps that had their coins at centralized exchanges for years, in Mtgox, Bitstamp, etc. And by the over-the-night CEO/COO, C-my-ass dragqueens like Ver, Karples and other scammers. At no point in the whole history there was a system subjected to such scams, thefts, sheer incompetence and stupidity. And think well, just the recent 19k btc is a big portion of whats currently in existence.

Otherwise bitcoin is good to go.
