i understand but by refusing escrow people start thinking i am a scammer ,
i don't mind use it with accounts ( i can change passwords later)
but the voucher is a bit problem
Using escrow is a old and reliable methods of doing P2P transactions. In a online transaction there is no way to trust somebody if he is not well recognized or you personally know him. In case of voucher i think there is a way to charge back the money even after few days but if you send any kind of crypto assets its gone forever. There will not be any way to get it back so it is bit risky to do P2P trade for a voucher.
