Hi,
right: paypal is reversible because if you open a dispute payment gets reversed and if youve sent btc already you can't reverse them, so you get scammed.
how are debit cards reversible? and also if i had selled you a physical item isn't that irreversible aswell once you have sent the
parcel..
Maybe with paypal you can claim you have sent it since its physicall and it doesn't go against the rules (like btc i think), but with credit/debit card?
Credit and debit cards can be chargedback
so i can basicaly go to any online shop buy with credit card get my order sent and then reverse it and scam them?
You could, but first of all that would be fraud. Second, in the case of tangible goods, the merchant would have a way to prove he delivered the goods you ordered and he could win the case.
In the case of non-tangible goods (such as bitcoins), the merchant will almost always lose when the buyer lies to his bank. The result is that merchants selling irrevocable non-tangible goods tend to not accept credit or debit cards.
Also because of scammers doing fake chargebacks, merchants often keep track of who does chargebacks (using cc cards or systems like Paypal) and blacklist those people on their sites.
