> 1) it has cash back;<p>That's only a benefit for a small percentage of people. If you're a middle-manager or salesperson, cash back on purchases reimbursed by the company can be considered part of your compensation.<p>I suppose the bank can negotiate with certain popular companies for a higher cash-back rate, which is harder to do as a bunch of individuals.<p>Outside of these, it's not really a benefit since it's included in the interchange fee. You might not notice it because your bank hides it with clever marketing, but it's there.<p>> 2) it has no fee in most cases<p>One common credit card fee is 2.9% + $0.30.<p>> 3) the payment is instant for the user, meanwhile bitcoin is much slower.<p>Payment is 6 months if you want to be sure. Anything less can be charged back. Bitcoin payments are instant if you're willing to immediately confirm, which isn't a bad idea on payments smaller than $50 or where it's a repeat customer.<p>The one area that you truly benefit from a credit card is in the consumer protection laws: You can chargeback very easily and it's tough for the merchant to dispute it. Bitcoin transactions can't be reversed, so if you get scammed you're out of luck.<p>The items you've mentioned are just banks out-marketing you. They aren't fundamental benefits. You pay for them with a markup that the merchant adds, and you also end up paying for a bunch of banks and Visa/MasterCard to exist.<p>Checks or ACH are better than both credit cards and cryptocurrencies, when applicable. Terrible security and a bit clunky, but very efficient for moving money around. And you can even get a card with a lower fee: I think the debit cards from major banks are 0.05% + $0.21, though you might have to convince the merchant to charge you less.<p>My ruling? For casual use, then - mostly because of the better security:<p>Credit cards > Cryptocurrency > Check/ACH<p>For anything serious, then - mostly due to cheaper transfer costs and assuming you can trust the counterparty:<p>Check/ACH > Cryptocurrency > Credit Cards<p>For guns, drugs & porn, then - mostly because you don't want self-righteous politicians or outraged soccer moms pressuring your financial processor:<p>Cryptocurrency > Check/ACH > Credit Cards
