To bad that mintpal was f*cked by scammers.
A new exchange that's been in the making for many months now has finally been opened:
https://exco.in/The people who've been building it are Blackcoin supporters, but maybe I managed to prop DRK to them a while back or they just decided it's a noteworthy coin to be added right from the beginning anyway, as the supported markets right now are BC/BTC, DRK/BC, and LTC/BC.
It looks just like Mintpal2 was supposed to look like imo.
