Actually, when looking at the value of bitcoin, they will immediately judge it as "expensive" but conceptually, bitcoin is a scarce asset, limited in supply and cannot be produced anymore, so in essence, bitcoin is cheap. You cannot judge the value without referring to the nature of that asset. Bitcoin is an asset that increases in value over time, not an asset that decreases in value over time like cash. Lol
In addition, currently many rich people who already have a lot of money, all will come in and buy BTC. They do not want their money to always be monitored by the government and decrease over time if they include items that are always subject to economic policies and I am sure that is true.
The last reason that is easiest to say is that BTC is an attractive investment vehicle now, in the future and in the future. if not, the price of BTC will not increase over time if we look at its history and will be abandoned, meaning that in BTC there is a promising value and technology in the future.
I agree with you that BTC is attractive because of its decentralized nature, protecting it from government surveillance and inflation. Moreover, history has shown that its price increase has great potential, supported by the ever-evolving blockchain technology. Therefore, BTC clearly has long-term value as the most profitable investment.
