So let me summarize this scam's modus operandi:
1. You want to use a risky and reversible payment method AND to top it off, you don't want to send first. Nice.
Next.
2. You ask... no, demand... that anyone taking up this offer must send the "measly" 0.2 bitcoins to you first. You seem to have just woken up after a long sleep.. this is August 2017 with 1 BTC valued at USD 4300 and not 2013 when it was $100 each in which case I would agree 0.2 would have been "measly" back then.
Reputation earned outside the forum is not transferable to the trust system here. You may have straight A's on other sites but they are null and void here. Escrow is a must (not sure if you forgot that in your post above or if you intentionally left that field blank).
Nobody should trade with this guy unless he agrees to transact more safely. If you value your bitcoins, send to him first at peril of losing them.
