It is fixed that Bitcoin will not exceed 21 million. So even if the demand increases over time, Bitcoin will not exceed the limit, so its value will continue to increase. And this is why bitcoin has given more profit than anyone in the last 10 years.
It has even surpassed gold. That is why big companies like MicroStrategy and Tesla have called Bitcoin Digital Gold.

Michael Saylor also says that Fiat money is a melting ice cube. Bitcoin is the fire proof vault
That's why he understood that investing in Bitcoin is safe and that its output will be profitable.
It is not difficult if we compare the development of Bitcoin and the development of FIAT over the last 10 years. The result: Anyone wants own bitcoin. And if we compare the amount of Bitcoin with the amount of gold and then the prices, there is a lot of room for Bitcoin to go up. Now it is only 5% away from a new ATH. The news in the world makes the price drop again and again. If it werent these negative events, the price would already be at a new ATH.
