Unlikely to "become money"? What does he think money is? I mean I do a job, and you pay me in a currency, and then I can use that currency for other stuff, it is an indication that I own that much, isn't that the whole idea of money? I mean the fiat that you have? Either in cash form or in digital form, isn't that basically saying you own that much, its a proof, and then you spend it? Thats all there is to it, nothing really feels different with crypto to be fair. I get that people like to talk down on bitcoin, but there is really nothing that changes, its the same exact thing as the fiat they use every single day.
