Nobody knows how the fate of Bitcoin in the future. Most likely, he will remain the first and most demanded among all, but this does not mean that there will not be many competitors around him who will fight with him for the first place.
for the first place with him, no one near can not. today there are enough coins which are much better than bitcoin and have not moved even closer to capitalization.
The time has come that the bitcoin is not the only coin in the market and that there are many other tokens that work a bit differently than bitcoin and that have added some other feature into their coins/tokens which makes them unique and special crypto besides the bitcoin, for example some coins have anonymity first priority then some other transaction speed and so on which makes them more favorable than the bitcoin.
