Why are you linking fiat to Bitcoin for no reason? Fiat is going to zero against Bitcoin. As the value of fiat declines, the value of Bitcoin goes up. It is not fiat, it is a commodity. If fiat goes to zero, gold doesn't go to zero. WTF are you talking about? Bitcoin is a commodity just like anything else. The only use it has is money. It competes with other money, they lose it wins.

It's not a commodity, it's a currency.
The whole "Bitcoin is a commodity" thing is a psyop, as is calling it a coin, calling the accountants miners, images of gold coins, etc
Define commodity - I suspect it will either be a uniform material or some incredibly complex definition that includes all the uniform materials + Bitcoin but excludes the other cryptos
Money is a commodity....
