Crypto is only as stable as people "believe" like any currency. The stableness of current currencies is based on how much people trust the governments that issued them. Crypto is an attractive solution to people in countries with unstable currencies, but competing with a currency like the US dollar or the euro...I can't see how it can attain that stability. I absolutely think that the US and the EU and other governments should think of moving to a system of currency that has many of the qualities of current crypto currencies but how can a currency inspire that trust just by existing without people being obligated to use it? I just don't see how the volatility can be taken out. If you're talking about a captive economy like within a game, I can see that. I can see games agreeing on a common currency and creating a reliable demand but as far as a universal currency that stays stable enough for day to day purchases, I just don't see how that happens.
