i'd like to bring to attention that mtgox made that much in fees in a month during that time period.
this means that most money is likely very safe and just unable to be withdrawn due to bank embargo or other issues facing them.
insolvency from that - not likely at all.
carry on bulls and bears.
of course everyone blames gox for everything - they are the big gorilla who's getting beat up bad. but, that gorilla may very well survive.
But what about the lawsuit mess: http://gawker.com/massive-bitcoin-business-partnership-devolves-into-75-487857656
no idea what will happen re that. however, that does not affect their going concern at the moment.
