Let me try! Credit cards make cryptocurrency (which doesn't have broad merchant support, charge-back ability, and, you know, the literal "credit" part of it) entirely obsolete.
> The charge back is only important because people have to give away their credentials every time they make a payment.
What? A charge back is important so that a dispute can actually be resolved. What recourse does a regular person have if they are defrauded by the other party. Or if the other party didn’t hold up their end.
Small claims court seems to be one of the only options at that point. While it's still a valid tool, it can be a big pain to go through with it and I'd bet a lot of people would just take the loss. It also assumes a lot of things like being able to locate the party to serve them.
I agree that it's a thing, but the difference between a chargeback and small claims court if you're a person who wants to charge back a company is night and day. Almost nobody is going to use that avenue.
In the context of the existence of cryptography (and cryptocurrency), this is laughable. (Credit cards were invented before public key cryptography.)
Advanced cryptocurrencies enable a much more robust and diverse set of credit options.
