I think it is a little ridiculous to claim open ledger is hacked.
What is your bitshares username so we can check it on cryptofresh?
By the way, if you ever transfer Bitcoin to a Bitcoin ATM the same thing happens. As soon as you deposit to the ATM, the funds get moved even before the confirms get done, and before you are eligible to get cash out of the ATM.
When that happened to me, I didn't ask if the Bitcoin ATM was hacked. I called the support line, and they said, "that is because we sell the deposit right away" but incase there is a Bitcoin fork or something else, we require more confirms before the machine pays you.
You on the other hand, assume right away open ledger is hacked (which is wrong), please be careful posting things like this... it is alarmist FUD material that isn't necessary.
Jumping to conclusions isn't very good for Bitshares or the community.
