I would accept 10% withdrawals-fee and a daily Limit of $50, but for all users and no monthly limit.
Nobody would trade on exchange with 10 % withdrawal fee.
What Cryptsy can do?
1) gives full disclosure of their assets,
2) open withdrawals for unaffected coins,
3) reduce operational costs by shutting down of unprofitable LTC and XRP/altcoins market and leave 50 coins with best BTC volume in the last 6 months,
4) back trade fees as more profitable option,
4) BV find investors or put mortgage on his business and personal properties or sell unnecessary assets(or combine) to take loan enough to cover 50% debt ~ 5000 BTCs,
5) other 50% will be paid from 0,5% withdrawal fee which would be auto-deduct from debt to every user during theirs withdrawal and
6) from 33% of exchange income(trade fees),starting 3 months after reopening,so exchange will have enough time to recover.
