if you want to buy ETH must use escrow for it or you can explain the OP above, if you do not use the escrow many people will be wondering about it for you.
I don't know how to use it. Plz tell me more
An escrow is a middle man. there are some very trusted users around the forum that would act as middle man for these type of transactions. usually for a fee. YOu can find a few of these trusted users offering there services in service section.
Yes, what he said was true, so if you use the escrow may be better and safer for you to buy or sell Bitcoin altcoin or whatever it was, so that no one harmed or harm one another for it. all are confirmed with escrow necessarily safe.
