I wrote about how cryptos are already faster than credit cards as a common misconception is that Visa is actually processing transactions.

They are processing authorizations only - no money is changing hands. Crypto is already ahead as the funds change hands within an hour (in most cases).

Great point. It's really easy to compare apples to oranges with this stuff. Hypothetically, there's nothing stopping Visa from doing what they're doing now using btc instead.

I doubt we'd actually want credit card companies in a full cryptopia, but probably reputation could accomplish the same thing. If Bitcoin is too slow to buy a coffee, you include your identity with the transaction and it's safe to take it on 0 confirmation.
