Dedicatedpool does not agree with rolling back. Bittrex should not be forced to lose BTC on this matter. Dedicatedpool has stayed on the old wallet, and Bittrex will as well.
This was not Bittrex's fault. Shit happens unfortunately, but you can't except them to take the hit on this.
If Bittrex stays on the old wallet, how are you guys going to sell your NJA?
