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.
You are correct, we should not be concerned about the future; we know what will happen, thus we should stop predicting it because bitcoin is a solid coin that anybody believes will climb despite any challenges. If you think bitcoin will fall in the future before the time comes, they should have found another alternative that will solve the problem because nothing is impossible in my opinion. Did you know or bitcoin can be spear everywhere and becoming fait money and be using it to purchase anything will like because I believe that all the government that doesn't like bitcoin to operate in their country will surely agree one day if they see how it is increasing, because is very hard to move to a country that doesn't know about bitcoin and many people are investing on it, so I don't believe that bitcoin can't be available one day because how people are coming everyday and be interesting on bitcoin investment to get profit, so that is how I believe that he will stay ever except they is not network to access it anymore, just continue investment and stop thinking wat will happen in the feature since he as not yet exist. Focus on what is happening now, and all is about investment and trading.
