Understand What Money Is,With dollars, your yield is to help you maintain purchasing power over time. But you don’t need to find yield to keep pace if you have a scarce asset. A great example is the median home price in the US – in 2018, it cost 24.5 bitcoin to own, and today it is 20 bitcoin. If we had saved in dollars, you’d need 30% more today than in 2018 for that same purchase.
