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.
It's only resistant if you HODL them or at least you have accumulate so much in your wallet. The problem is that not everyone is on Bitcoin yet and so when their is a economic collapse we might be safe but there will be a lot of individuals who are going to be hit very hard. It could be a lessons for them though, and perhaps this economic collapse could be a good teacher for them to find out what Bitcoin is so that the next time we have this kind of crisis, they are somewhat going to be safe just like us. Another great example is during the pandemic wherein Bitcoin proved itself to be a good hedge that time and maybe people survived or at least their money didn't lose value and on the contrary grows because we had a great bull run in 2021.
