If merchants began directly accepting bitcoins, they'd drop the CC fees out of the purchase price. Only #2 remains a use case for CCs, and they're also one of the reasons merchants hate CCs--chargebacks.
i dont get why you'd use bitcoin over a credit card for legal goods
1) fraud coverage (yes i know this is less likely with bitcoin but what if someone steals your wallet or whatever)
2) can dispute transactions if merchant screws up
3) 2-3% cash back
i realize a credit card is not a currency, but people are using bitcoin as a payment, not just as a currency. i guess a CC could use bitcoin behind it but i don't know if this exists?
Because **** the banks and their entire corrupt system of debt slavery?
I bought a $30 bag of weed for $60k of today's bitcoins a few years ago. transaction went fine, but I don't think I'd do it again, getting a smelly package in the mail was a little suspicious
