Because BTC can't be created out of thin air limitlessly, I'd say it's much more "stable" in that regard.
The chart below shows how out of control the money supply has gotten in 2020. It's inevitable before this mass printing of money translates to big inflation in the economy.
The amount of products I can buy for 1 USD was far more stable over the last year then the amount of products I get for one BTC. That's the kind of stability I am looking for in a currency as a consumer.
