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.
Thanks for your comment, @btcpoland.
As @tonykay said, pesetacoin team is working hard to develop and implement new specs on PTC.
Great developers and great team working on a Foundation. You can check all this info on the spanish thread full of discussions about it

Have a nice day!
