2) Nobody is forcing you to hold large quantities of cash. In fact, very few people or institutions do. Most portfolios are 90% 'other stuff'. Cash is for liquidity, it's never really been as a store of value. As a currency it works well.

2. I’m holding as little cash as I can and trading it out for Bitcoin and Ethereum every chance I can get.

This is exceedingly unwise. You may get rich, you may lose your shirt, probably something in between, but you're putting hard earned money into monopoly money controlled by a very small number of people who are either jerks or criminals and care nothing for the system.
If they want to hedge against inflation they would be buying real estate, equities and commodities - not magical monopoly money.
