He told me he traded successfully with frediiii, GröBkAz and i sent him 1000 YAC, but he didn't send me LTC.
I suspect those nicks are belong to him, just fake trades.

I traded loads of coins with him in the first few hours the coin started for a very, very low LTC price compared to current prices. My bad, but at least I got my LTC.
He wrote me again today If I'd do more coins for the same rate so I just opted to sell to 1234r who pays even faster and quite fair rates.
If you want to sell coins, do it with 1234r. I trusted him with 13kYAC upfront in the last transaction and sold him over 30kYAC in total over the past 2 days.
And nope, my account does not belong to "ChinaCoin"
