Gold hasn't been doing that great as a hedge against inflation in the last couple decades.
I think the problem is that those guys keep hyping up Bitcoin as a hedge against inflation because, eventually, when all this volatility ends and its price action is more constant, yet, Bitcoin on paper is eventually good hedge against fiat currency. It's literally designed with the store of value properties of gold (without the disadvantage of weight).
Yet right now even after 15 years it's still new compared to gold, and everyone speculating on it keeps it volatile as new people keep jumping in and buying and selling. In my opinion Bitcoin as a store of value and a hedge against inflation will happen, but not for 15-20 years. It's too useful as a speculation market.
What about the other altcoins that have crazy action (like the coins that spike 50X-10000X in a year)? Those are too esoteric to the average investor, and Bitcoin is a name people know by now. It's the one institutions are planning to bring ETFs for, which will bring in more mainstream investors. Even more if federal regulation hits this year, which brings in more investors and will smoothen out volatility.
The entire crypto market, even with this dip, is under 2 trillion dollars. Bitcoin in over 1/2 a trillion in market cap by itself. It's been 15 years guys. It's not going anywhere.
