FYI - I had some ACH (USD) transactions from the weekend pending when bitfloor went down that *did* complete this afternoon.
As Roman promised these transactions were not stopped/interrupted.
I would assume that had he been the culprit these monies would also have disappeared.
It's much more dangerous to steal USD than Bitcoins. Also, if it was Roman, how would he explain the missing USD? (Not that I'm saying Roman stole the coins, I'm just saying this reasoning is very flimsy.)
