The price of a house used to be 100 bitcoin, then 10, now it's 5. Wait 10 years and it'll be 0.5. Meanwhile, hold dollars and the price keeps going up. You are defacto forced to put your saving in an investment vehicle to keep up with inflation, taking on risk.
Yes. You got it. That's how you get economic growth. Instead of stagnation and deflation when you hoard gold or bitcoin. It's not exactly fair from the individual people perspective but for the society as whole it's objective the superior option.

I know that reading comprehension is hard (even if the "IF" was in very big letters..). If your income is in $ and you buy stuff priced in $ AND you don't want to use crypto as an investment instrument but only for buying/selling good holding it for extended periods of time is not smart (same applies to foreign currencies in general they are just not as volatile).
