Re: If bitcoin price is $10.000, will fiat be worthless?

Bitcoin could reach 10k without fiat having to go through hyper inflation or anything, if adoption grew by 10 times the current amount of people and business, then it stands to reason to believe that the price will grow that much, so fiat will not be worthless in that scenario.

Well the price suggested here is ridiculously low for the fiat price to become worthless. Multiplying the adoption of Bitcoin by 10 would still leave it an absolutely tiny currency compared to, for example, the US dollar.

Correct, 10k for bitcoin is not enough for the world economy to function because we know there is a limit in the number of bitcoin, I have not done the math but bitcoin will probably need to reach at least 1 million per bitcoin to be able to run the economies of the world.

Good observation. Also, may I add that Cash has unique properties because it is a physical token of value. Many transactions made are not made to be seen by the public eye, and cash facilitates this, it is the ultimate anonymous value transfer mechanism. Also, if it became a world currency, we would see individual governments have unique currencies. They would not late adopt into a global currency.

Indeed. I also don't see future transactions surviving on digital currencies alone. Digital currencies pretty much rely on things that can easily be taken away like online connections. I din't even think btc reaching 1million, which is pretty impossible, will cripple and kill fiat. Not by a long shot that is. Unless there's a currency that would be as accessible as fiat, i think it would stay
