I knew Bitcoin as legal tender wouldn’t work long term because most people don’t know how to use it. This is similar to people paying their debt in Pennies to piss off the impound yard or ticket agencies. But they have to take it since legal tender means a debt owed.
Making bitcoin legal tender I assume was more for publicity than actually solving any issues. And I wonder how many actual debts got paid by bitcoin, probably not many.
Most people these days leave their BTC in the hands of a custodian (centralized entity). They only know how to buy/sell Bitcoin. But not how to use it as true, P2P digital cash. It's no wonder why governments are only interested in building Bitcoin reserves. Not spread BTC's use as a currency.
El Salvador was the exception because it wanted to "break the ice". Turns out its experiment failed, as most people claimed the rewards from the Chivo Wallet and forgot about the rest. Not even a mandatory use of BTC did any good. The odds of other countries following El Salvador's footsteps are slim. But who knows? Maybe things will change in the future as Bitcoin finally addresses its scaling issues. For what I've learned, anything's possible in crypto land. We'll see what happens in the long run...
