This guy is clearly scammer. He accepted my offer first, i am going to sell him 50k bismuth for 1.5 btc.

He asked me to sent some bismuth test coins to prove that i really own 50k bismuth. I sent some then he suddenly said that 'you ll send first'

He is a newbie and he wants send first from you. He did not even mention use escrow or something else.

Moreover he have not send my bismuth test coins back.

Stay away from this guy everyone.

I am still willing to sell 50 k bismuth for 1.5 btc. Pm me if you are interested.
