I constantly here people say " Only invest what you can afford to lose" Well no matter where your wealth is it could crash.
-Invest in USD- USA could collapse and experience mass inflation making your dollars nearly worthless
-Invest in Bonds- Government could collapse making your bonds worthless
-Invest in real estate- Housing prices could crash, natural disaster could hit and insurance company could go bankrupt
-Invest in metals- prices could crash, asteroid mining could collapse prices
Your money is never 100% safe no matter where it is invested.
You're absolutely right. But obviously, the saying is still absolutely valid.
It's all about the risk and the reward in my opinion. An asset class like fiat cash would obviously be quite stable in the short run, but its value would drastically depreciate in the long run given the inflationary nature of the currency supply.
Same with bitcoin - in the long run, I wouldn't doubt that it's a store of value given its capped supply, but in the short term, there is risk that prices will go down due to a bear market.
Everything and anything have monetary risks and can appreciate and depreciate. What matters in terms of finance and investing is diversification of these risks in one's portfolio, in my opinion, unless you're absolutely certain that one asset class will outperform the rest, which I believe is pretty much impossible.
