You will definitely get proof of how inflation happens, you deposit fiat currency in the bank and after a few years determine its value and go to the market and prove it. And you deposit Bitcoin with the same amount of money and hold it for a long time then you receive the benefit.
You prove whether Bitcoin can be more profitable or you can be more profitable by storing fiat currency, only Bitcoin will be the best because its value will definitely increase more and it plays the most effective role against inflation.
You see the comparison becomes even more significant when you focus more on the purchasing power rather than simply the amount of money held. Yes, it’s true that inflation can make fiat lose purchasing power over time, but there’s also no guarantee that Bitcoin would increase or rise within that speculated period of time either, because Bitcoin is a very volatile asset and price can go from this to this at the time you least expect, especially when it’s during the short term. So the most important thing here is understanding the difference between protecting purchasing power and simply taking on an asset with its own risks too, that way you’ll be able to make a more logical choice.
Inflation has is actually about purchasing power. If a particular amount can buy same commodity after many years or after a period, then inflation is non existent. Bitcoin bridges the inflation gap by rising up to the current price of a particular commodity or even higher. Even though it is not certain that bitcoin will rise at the end of the period or whether it will dip further, it is still riskier to save money in fiat because based on history, bitcoin has performed better when compared to fiats
Inflation is continuous and so is bitcoin, volatility makes it possible to rise and fall and over a period of time, bitcoin seems to have crossed a particular low, which is why long term holding of bitcoin is always the best. You don't have to limit your investments, you should have a plan of holding for at least 4 to 10 years because that's when you can consider your self an investor. The longer you hold, the better and the shorter you hold your bitcoin, the easier or the higher chances of losing because it becomes like a trade/short term trade.
