Reputation requirements result in higher prices for buyers, as it's hard for new entrants to come along and gain meaningful business, while the older entities suddenly have the incentive to "milk" the reputation they earned.

Meanwhile, with a credit card I can buy a product from Amazon or some joe-schmoe site nobody ever heard of, and have a guarantee that Visa will back me up if the latter is a scam.




You're paying those prices for Visa's reputation. Visa takes what, 2-3% of every transaction? Also, Visa has a record of every transaction you've ever spent. And as the Equifax case has shown, even big players aren't immune to hacking. You know what's pretty resilient to hacking? The blockchain itself.

At any rate, the advantage of Bitcoin/Ether is that sending Joe Schmoe your money doesn't mean you've exposed your credit card number and billing address (likely also your physical address) to Joe Schmoe. So there's pros and cons to either system. Refunds have existed since well before credit cards were a thing. Does it require a bit more of "buyer beware" ideology? Sure, but I don't think that's any different than a cash-based society.


I'm paying roughly 3% out of which I get back 2% through cashback on my credit card. For a net fee of 1% I get buyer protection and dispute resolution in case I and seller disagree. The higher the sum, the more likely I am to be interested in such protection.

The move to chipped credit cards (or Apple/Android Pay) also shields my real card number and makes information unusable in case of hacking. I already hide my address by having the card statements go to a PO Box and using that as my billing address, but I know that's not a widespread practice and some institutions forbid that.
