For some people might say something like that will happen, but maybe there will be a way to deal with inflation without having to run to bitcoin, inflation has always existed even before bitcoin, and that problem can also be solved. we just don't know for sure how it happened. CMIIW
There can be another ways to hedge against inflation, like rare metals like gold, platinum and silver or something rare like limited in suppy. You can also do stocks or real-estate, it's up to you depending what kind you prefer to invest to temporarily escape from inflation.
Although among those choices, still I can say that bitcoin is the best and safest bet anyone could invest because the value is indeed rising quitely due to supply-and-demand. If you choose to hold bitcoin then you're in the safe hands and the risk is minimal.
