Inflation of 3% over the next several years compared with the extreme volatility of bitcoin isn't even a question. The dollar wins hands down. Your bitcoin could be worth $40,000 next month or $20,000. That's not protection from inflation. To actually protect against inflation, you need something that holds a steady and predictable value. Not that I think people shouldn't own bitcoin, but they definitely need to not delude themselves into thinking they're protecting themselves from what is ultimately still a low inflation rate by doing so.
yes I agree with you, but in my opinion bitcoin is a store of value. Store of value itself is something that does not depreciate over time. Usually this medium store of value is rare and cannot be easily devalued. This is what causes Bitcoin to be categorized as a store of value. The best thing you can do with bitcoins is store them so you can protect yourself from inflation. Even though bitcoin is volatile, if it is withdrawn over a longer period of time (logarithmic chart), the value of bitcoin has remained or even increased drastically in the last 10 years.
