Reasons Bitcoin Will Replace Credit Cards

There's a difference not noted: credit cards give you credit, which is why you have to apply for them. When you use one, you aren't transferring your money to someone else, you're transferring a third party's money, with a promise to pay them back later. Each transaction is a tiny loan. In the bitcoin scenario described, it is more like a cash transaction, you have to have the bc in your wallet. And, of course, bc is way more complicated than a cash transaction.

This is more like a list of reasons why bitcoin will not replace credit cards than a list of why it will.

The reasons "charge cards," as they were originally called, were invented was to make it more convenient for customers to pay. From the day BankAmericard (now Visa) launched, normal people could use it in normal stores to buy regular merchandise. This has never been the case with bitcoin and is unlikely to become the case without significant tooling and user-facing help that simply doesn't exist now.

If there is so much money in crypto, how come no one has addressed the terrible UI problems? Until your mother can buy something at retail with bitcoin, it's not a payment method.

The banks who, together, developed the modern card system (debit or credit makes no difference here), have already solved the problems of availability, scalability, and reliability.

In addition, they have solved the problems of reponsibility and refundability which are critical to any financial transaction and which bitcoin and its players refuse to address.
