> Meanwhile, Bitcoin has been around for 17 years and there still are no non-criminal use cases apart from buying it and hoping it will be worth more in the future.
That is plain and simply false. It works just fine as a currency, and some legitimate businesses even accept it. I think it's true that Bitcoin is not particularly useful, but that's not the same as there being no non-criminal use cases.
It doesn't though. Go to your local Wal Mart, Costco, Home Depot, Target, etc. and try to make a purchase with it. Go to a local supermarket or restaurant and try to buy food with it. Stop at a gas station and try to buy fuel with it. Go to Amazon or eBay and try to make a purchase with it. Go to an airline or hotel website and try to book travel with it. Go into your Uber app and try to pay with it. Call your landlord and try to pay your rent with it. Objectively, it doesn't "work just fine as a currency" or we'd have empirical evidence of it actually being used as such in real life.
