Fundamentals.
It's about assets. The best of the assets are productive. Some items and commodities carry a speculative value because they are rare. It's obvious where crypto falls. The thing about productive 6 that they produce a real return. They don't just go up in value because the dollar is worth less. They legitimately produce goods and value above the rate of inflation.
I just saw the post about the Zimbabwe trillion dollar bills. "Where all fiat is headed." Well, the US dollar is in no way comparable to Zimbabwe, obviously... The question is, do they understand that (minus a devastating period of hyperinflation/economic destruction like Zimbabwe) when fiat inflates the value of assets, especially businesses with pricing power, also does the same? Do they understand the point of capitalism? Do they really think its only Bitcoin that will rise relative to fiat? What's the point of bitcoin if the entire economy is gone and the only thing that has value is food/water cigarettes and bullets? That's how some of them view the current system doomed to fail... where even the best and most productive and profitable companies in the world are being ' "eroded" by the inevitable collapse of fiat.' The most extreme of them foregoing any normal investing to just pile into the "future bro".
Please, for the love of God read some books and think about the big picture here. I'm not coming after the guys who just want a "little bit" of speculative shit in their portfolio. I'm talking about the maximalists. What good is BTC if we are all fucked? You think BTC will be the key to your future consumption? You do realize that consumption will still be in fiat and will still be all in a complex system of companies competing for growth and market share. Many of which you can own directly through a low-cost index fund instead of some digigold. Even if BTC holds its "value" relative to fiat, you will still be underperforming any real-return asset, including corporate bonds and maybe even treasuries, in many periods. If you disagree, then explain to me why I should expect a real return from an asset that doesn't do anything? I can only think of one. Initial price discovery, and then that's about it aside from supply shocks like suddenly destroying millions and millions of sats.
