Bitcoin is very very volatile and just because it went up the last x years, doesn't make it stable or trustworthy.
My money in my bank is very safe and it doesn't cost me anything.
The inflation itself is a systematic thing and should affect bitcoin equaly.
When corona came, i was looking at the stock market and was surprised how many people left it. It doesn't make much sense to distrist the stock market that much. After all alot of pension funds are existing, lots of companies or people who are self employed also have to keep their money safe. There is a lot of dependency on the share market and we are all bound to a certain degree of not being able to move it out asap.
