Well. he can paypal to me. and then me to the seller..
Same goes for the BTC.
So if he does decide to scam.. Only I will get charged back.
In which case. I will hunt him down and shake the money out of him.
I am assuming the risk and allowing the buyer to build up some rep.
That certainly is a unique proposal, I've never heard of an escrow willing to take all the risk. If the deal goes through, hope there isn't any wishy-washy business by the OP at least for your sake.
Also, a person cannot indefinitely perform chargebacks on a verified account without raising suspicions.
True, but it isn't that hard to log in from a different IP and then make the payment and then claim your account was hacked. I don't think they'd bat an eye at preventing what they see as fraud and theft.
