Lets not compare bitcoin with the way other financial currencies operates, because they are all under different network and technology as well as system, when it comes to the effect of inflation on the market, bitcoin remain unaffected while other fiat currencies are being involved in the reactions towards which the inflation had upon them, that is why we could in most cases see a degradation in market value and currency value as inflation set in.
It should not be compared in terms of how it works because even though bitcoin has advanced in terms of technology and different systems, they still have quite significant differences. Bitcoin is resistant to inflation so its journey is considered as one of the assets that can maintain value while fiat currencies continue to experience depreciation in value so that when inflation occurs, it actually worsens its journey. Fiat currencies also lose value in the future and there is no potential for storing value so in that capacity bitcoin is much better for someone to use.
