Is it possible that Bitcoin could increase its total supply in the future? But that would certainly cause Bitcoin’s price to drop significantly.
Could Bitcoin switch to PoS like Ethereum? That would also cause Bitcoin’s price to fall.
There is no need to worry about the future of Bitcoin and Don't be discouraged by the issue even though PoS is considered more energy efficient, everything has been neatly structured by Satoshi, there is no reduction or increase in the supply anymore and only 21 million Bitcoins.
We will not know what bitcoin will be like in the future, which is certain that he is and also does not need to be worried at all because bitcoin is believed to always increase in price in each cycle it is a very strong belief in our hearts, especially miners, bitcoin will always increase along with fiat money that continues to be printed by the government.
Will not move to PoS it is too much risk and may experience a crash if done like that, I think he is still new and does not know Bitcoin has an amount that cannot be added anymore.
