It's a half scam I think. It was legit some time ago and now just look abandoned. I got my pxi deposit after 3 days, sold it, but i'm waiting forever for btc withdrawal. Someone said recently he got btc withdrawal after 2 weeks. It's only 0.03 btc, i'm not stupid, i knew something  fishy is here. Anyway, the guy is from Poland. I will try to find him if i get some free time.
