The problem with using BTC or any other "crypto" token as currency, is that it's not "legal tender" [1], aka. something that law guarantees can be used to settle debts with. For something to be an actual currency in our world, one minimum requirement would for it to be legal tender. "FIAT" money is legal tender. If I have a 100 dollars in USD, and a debt of 50 dollars, I can settle that debt, period. If I have a 100 dollars in BTC, and a debt of 50 dollars, my ability to settle that debt relies completely on the creditor to accept BTC as a form of payment. Which is entirely up to the creditor, as he isn't legally required to do so, unless we have an enforceable contract that says he has to. As long as that doesn't change, and given the fact that the entire value backing of crypto tokens is based on the money invested into them, it is highly unlikely to happen in relevant economies, crypto tokens will not become a widespread currency. A lot of people laud the fact that crypto is free of government influence. The problem with that is, that this government influence is exactly what makes money work as currency.
