Don't fall for this, he can make all screenshots he want, fact is, 1FYyHeSHy47NTiEBBYs3HAwsss8b3oYK3N sent 0.00792085
BTC.
Proof it never sent a zero-amount.
i received payment on bitcoin ($63) and guy who sent asked for a refund
Now I'm curious: why did you receive a payment, and why did you ask for a refund? Was it a scam from the beginning?
I'll second that. The blockchain is the unassailable truth. What some anonymous guy said is just that, what some guy said.
