How I got scammed? That is why I say I am stupid, really stupid!! He wasn't even tricky.
1. He was a new user, registered for about a day
2. He asked me for the code to send along with my bitcoin-address
3. I asked him if I could give him just two of my three codes first to see if he is a scammer (why didn't I send just one? or a cheaper one? ^^)
4. He told me he would use a bitcoin-anonymiser and it would take a little longer
and yeah, never received the coins - why the hell did I trust him? That was plain stupid, and I always thougt "no way I am gonna get scammed" haha yeah
Learning something for the next time
Oh and he said he would give me 9 BTC for about $160.00 and that wasn't suspicious 'cause it costs right about that amount on MT.GOX
edit: Question: How would you trade with PSC? Make an escrow or what? That is what confused me and why I trusted him I guess...
