Lol nobody gonna want to use an extremely volatile currency as payment processor. Rest of the world just needs to implement system similar to PIX from brazil.

Crypto isnt a payment processor, and it has no backing as a currency except current social agreement (yes thats most money but issued currencies are backed by central authorities) and it basically exists for ponzi schemes. Its so insanely volatile that its not for every day people.

That's not even mentioning that its sole value is to convert back into regular backed currency.

Yah no, it has to be more stable I don't want to one minute be paid a fair price and the next have nothing or have paid 2x what the thing was worth.
