@PeterSkrzyniarz Or use localbitcoins.com but make sure to choose someone with a good reputation to trade with, there are some scammers in there, specially in gift cards and such ;D
I traded one time with one guy from my country for a bank transfer and all went well aswell as being pretty fast and actually i catched an offer where i was payed even a little more than what poloniex said my btc was worthed at that time... Good luck with it ;P
