Crypto is barely being used as an actual currency. It does have nation states buying it to it though. It's value seems to be serving *more* as a pyramid scheme than a currency. MOST people are buying into it because they think they'll get a return, NOT because they want to buy and sell things with it. It's the only future for businesses that the system is shutting down through the banks. HOWEVER if crypto TRULY becomes a threat, you'll see nation states making big moves against it. Think they won't do what ever they want when they want? Look at covid. Regular dollars - widely accepted, banks don't give out my transaction info to just anyone. That's about it. I certainly don't TRUST dollars, I'd rather have money stored in something of real value.
