So I guess the question becomes, where exactly is the money raised from the altcoins? The deposits appear to be fairly well staggered, so if there was some problem with withdrawals, the deposits would logically have stopped. Further, there appears to be a withdrawal that can account for a portion of the bitcoin cash, although some of this money is also still missing.
It depends if all the altcoins went to the same exchange account, then. But that is pretty interesting...
I'm still not sure what has happened with the altcoins and the now locked/changed password exchange account. It may be that the personal owner of the account changed the details after the business was done as well...exchanges need identifying information and bank accounts attached to them.
