It's amazing how this guy seems to consistently forget to delete his traces. From his email being public, to all those transactions via clearnet, without mixing coins...
It's amazing he did it this far.
PS: I'm not defending him. Neither condoning him.
Based on the spreadsheet that the prosecution has presented as one that Ross was using to keep track of SR's finances, I would say that the 144k
BTC was actually belonging to SR's customers. Not long before he was arrested, SR was actually over a million dollars in the hole because of all the people he had to payoff that were blackmailing him and from the $2 million theft/loss from gox
I don't think he was actually intending to use any of the bitcoin for his own personal use, but was holding it on his laptop for security in case the SR servers were to get seized (along with the private keys) - it was essentially "chilly" storage
