New withdrawals are currently on hold while I work through the future of the exchange.
That is unacceptable. Regardless of the future of the exchange you have an obligation to disburse funds to the ACH account on record. You previously handled requests by email. USD funds by depositors are the property of the depositor and not an investment. You have no legal standing to hold those funds pending "anything".
Since it seems shtylman missed it.
Let me make it more clear.
You wanting to continue bitfloor is admirable but it has absolutely nothing to do with client funds. The only purpose of those funds is for CLIENT to purchase bitcoins. Since that is no longer possible the funds should be returned immediately. Not in week, not in a month, not after you get "hacked" again and the attacker makes a bank wire withdraw of all the USD funds to some foreign bank.
ya sending everyone's money back seems like a good first step.
then rebuild a better system, and start making money again.
