Just like gold, there are thousands of metals produced such as steel, aluminum, silver, etc., which are widely used in daily life. but gold has always been the most valuable metal, still number 1.
So there will be no altcoins that can replace BTC although ETH, Sol, Tron or Xrp... have utilities, applications and technologies that are far superior to BTC.
It always about the Crypto enthusiast choice, but right now generally Bitcoin has more holders , for now and things are fast changing, even if Bitcoin would still be relevant in the future some Alt-Coins would also be up there.
