Seems to be fine on crypto reserves.
I wouldn't assume either way. It's certainly possible that they are insolvent. But they debited 39-45% of peoples' funds from their accounts to account for that shortfall. It's very possible that the admins were selling coins OTC to rebuild their fiat reserves.
We also don't know how much of their fiat reserves were actually frozen and how much was sufficiently unaffiliated with BTC-E. I think their bigger problem is inability to easily move fiat, which is no surprise. We know none of Mayzus' companies will work with WEX now.
