Sure, investing makes tons of sense, but does that mean checking and savings accounts shouldn't exist? Individuals are better off with the bank accounts denominated in a currency with a fixed supply. That's so clearly true to me that I don't understand why you disagree. A widely adopted currency with a fixed supply will slowly increase in value as the demand to perform transactions in that currency increases. The whole point of central bank currencies is to make sure the value slowly decreases over time. Sure, it's good for the economy, but individuals don't make choices based on what's good for the economy. They look out for number one. "Not all cryptocurrencies are deflationary." Inflationary cryptocurrencies will not succeed. Imagine there was no dominant currency in your country today. You gave goods or services to someone, and in return, they give you a choice of payment in two currencies: one with an increasing supply and one with a fixed supply. Which would you choose?
