In your heart you must see this is just a fantasy. Shrink money supply 99%?! How would that even happen, and why would you want it to? The USD is not ceasing to exist anytime soon. More realistically the Fed is going to incorporate the technological advances introduced by crypto into USD and make it more powerful. Just because vendors will take crypto, doesn't mean the end of fiat. It's a straw man argument to say its either crypto or fiat! Neither are going anywhere, and crypto isn't money for most people and never will be. If the USD disappears, then the US is no longer a country, and yes I get that things change, and do I know what the world will be like in 50 years, no. But I'm confident, that in 10 years from now the US will still be a country. And if that is not true, then trading crypto will be the absolute least of all our worries. Oh, jeez, I'm getting trolled aren't I? Falling right into it. Darnit!
A couple things can be true here
I also don’t think fiat currency is going anywhere anytime soon. I also think people that don’t invest in bitcoin, because they think fiat currency will exist, are missing out and asking the wrong questions. Maybe bitcoin can be some sort of a replacement in the long arc of history, but we’re not even close to that point yet.
But to cast doubt on the above comment of bitcoin buying a car, and in the future, it’ll buy a house in my opinion is wrong, too. Don’t take my word for it that is objectively what bitcoin has done in its history, and while potentially that could not repeat in the future, you’re gonna have to explain to me why this train just stops here?
