> Good try, but trite criticism regarding crypto is required to include the words "Ponzi" and "tulips"

Thank you, I'm trying to come up with an "anti bullshit bingo" since the bullshit bingo from cryptocurrencies has already managed to raise tens of billions of dollars. Glad you like it.

> Quite an imagination! You're very far off, do you have any experience in this space?

I was trying to be generous since crypto supporters always like to point to the newest barely working bleeding edge centralized "layer" called lightning or thunderbolt or some other electricity derived thing, which is supposed to greatly accelerate the glacial rate of crypto transactions.

Again, can I use crypto of any kind to buy $2 peanuts at the supermarket in Bucharest and grandma $1 popcorn at the cinema in Djibouti, without turning Earth into Venus?

Probably not, but you can neither use USD (or any sort of dollar) for that either. In Bucharest you'd use Romanian leu (RON) and in Djibouti you'd use Djiboutian franc (DJF).

It's all about finding people in the middle, to agree on what you both have. In this case, you wouldn't be able to buy anything in those locations.

You can do both of these things in El Salvador right now.

What single currency allows you to buy peanuts in Bucharest and popcorn in Djibouti right now? (You seem to believe the US dollar for some reason)

Most of my credit cards will without a fee on my side, based on my understanding.

Sure, I'm not paying dollars necessarily, but that's how it's treated on my side. But I never used my ccs in person overseas yet

Exactly like crypto credit cards. What single currency?

Like my normal dollar based credit cards that allow foreign transactions and have no foreign transactions fees...thr processor converts thr currency to dollars for me and puts it on my statement.

Nothing crypto specifically solves as a user.

Agreed, exactly like crypto or a money changer. Nothing specifically solved as a user.

> Nothing specifically solved

Besides permissionless transactions? Does your credit card offer those?

Do you pay monthly fees for the privilege of not paying fees on foreign transactions? I do :(

Which single currency satisfies the GP's description?

I want my transactions to have permissions. That's a feature of the system. What happens if someone fraudulent spent my crypto?

No fees on any credit cards I keep, except 1 which was waived this year when i called to change it to a free card.

So they do charge fees (for you and the seller, also a user). Sounds like a problem with the company you require permission from.

If irreversible transactions worry you, use an intermediary; the way you already use credit instead of cash (which requires no permissions).

Any single currency?
