I feel like at the time I got most of my altcoins out and I do see a BTC withdrawal the day before I think they were taken offline, but I don't know if it was all of my BTC or if I maybe had more. Have they been able to verify balances by date and time of withdrawals or anything? Maybe I'd have to find whatever old wallet I may have withdrawn to and find the tx hash? Pretty sure Mintpal was dumb and didn't include the hash or addresses in email withdrawal confirmations.
I'm not sure if they have database backups. Did Kennedy wipe the database? Does anyone know if they have backups of old snapshots?
