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?
