What? Someone actually bought these? Is there any crypto solution for this kind of transfer? Seems to be a big issue with cyptos, how would you verify a transaction like this? Or if you bought something using crypto and didn't get it, how would you get a refund?
There is no refund in cryto that is why use a reliable escrow. Easy to verify the transactions with block explorer. There is not going to be a problem to verify the BTC and NEO transactions. The escrow service is make sure both parties are safe from scam.
