I'm a cryptocurrency advocate, but for the average person transacting with crypto is still insanely intimidating and a pain to set up properly. Maybe paying with stablecoins could work but that is still a lot to ask of your users who are accustomed to paying for things with a credit card.

Want to buy something? Open a Coinbase or Gemini account, hook up ACH or wire transfers, wait a week for the deposit to be made, then send 'dollars' to this really long and complicated looking address. If you send it to the wrong address you are SOL.

Crypto payments hasn't taken off yet. It's beyond the scope of most people's ability to pay in crypto.

To reach the masses you probably have to go with "know your customer" (KYC) requirements that are going to scare lots of people away when they have to upload photos of their passport and stuff like that to a website.

And governments and banks are going to impose the same restrictions somehow.

Unless they use a coin that is private, all transactions are going to be recorded in the blockchain and publicly viewable to everyone. Nobody wants their porn purchases to be public knowledge.

It will probably eventually get there but probably at least 5 years out.
