Don't waste your time people, this is the old scam where he bought a MM account without the 21 days hold and he wants you to send funds as Goods and Services so you feel safe because you can easily refund the payment, he will force you to send first claiming buyer protection and I would advise anyone to stay away from this user.
If I am lying he told me he has $500 btc and he can prove me wrong by signing a message using his BTC address and I will remove this post, I will aslo leave a negative message on his thread to warn others if he doesn't prove he actually has those $500 btc he claims to have.
The ratings on his account are all fake from his other newbie accounts to fool other newbies so he can scam them.
