This guy is a scammer. Don't trade with him or at least use an escrow.
Here is the scheme:
He claim to have an amount of bitcoin. Show you some printscreen so you get confident and ask you to send first.
He then create an new paypal account and ask you to send the money to this account. Thx for me the paypal system noticed that something was going wrong. When I asked him to send the btc he claims he has to the escrow (DannyHamilton), he suddenly became mean and refuse to do so.

While you can ask paypal for refund, this guy is a thief and a scammer that took advantage of paypal. Even if I don't like paypal policies and transaction fees, it's clearly not reason to accept they be stolen.

You've been warned!
