Mt Gox 30d volume $337m
At an average 1% fee that's $3.3, this is why its hard to beleive they are completely insolvent.
Can't be insolvent if they are cashing-out all the BTC they just earned, on the other exchanges...
Heck, they didn't say they had issues moving their own coins... Buy all the low ones on their own exchange, move them out, before we can, than cash-out on the other exchanges higher rates, before we can... Insolvency erased. (Unless the other exchanges are actually the insolvent ones, and thus, why they don't seem to want to let anyone cash-out, holding those markets purposely high, buying their own fake coins, to make it look like actual trading is happening.)
That is why regulation, to some point, is needed. Accountability and live public auditing. Or simply, Proof.
It will happen... These exchanges will soon have to provide proof of held funds, BTC and FIAT. Even if it isn't 100% of all deposits. (Like banks are allowed/forced to do.)
You want to be unregulated, just got to say.. "This is an unregulated exchange", to alert those who don't want to risk that potential loss.
