Quote from Mintpal website:
Important: Please be aware that we are phasing out the voting system. We have removed the option to make payment votes and will stop taking voting winners from 1st September onwards. The system will continue as normal until then.
So no Mintpal for PesetaCoin but maybe that's even better. Mintpal wouldn't help us and it could even harm PTC.
Bittrex is the best exchange right now I think.
