There is no objective measure by which Bitcoin is more stable than USD.
The idea that USD is becoming worthless due to recent monetary policy, however ill-advised, is greatly exaggerated.
The idea that Bitcoin is the only way to protect oneself against inflation is also greatly exaggerated. Investors have been buying assets and investments for a long time before Bitcoin was invented to avoid inflation. Bitcoin didn't magically change that.
