Why not take the amount you was stolen of from all the users?
+1. Or, if it's easier for you, just the liquid coins. Not fair that "just" BTC holders hit. If you happened to have had a position on, you're okay? That's not right. Likely 99% of people were "using" BTC as a conduit to get into and out of the exchange. So, those people need to pony up.
Also, don't raise fees Busconi. Pay us back slower if you have to.
IDEA: TAKE 12.6% from all withdrawals until funds are recovered. Revenue will be higher, cause people will be trading with larger BTC sums. And, people will leave funds with you, and likely trade more. You also
eliminate the risk of a run on the exchange completely.
Whatever,
I support Busconi, and I'll trust the exchange more now.
