BTC is not only the first coin but it has symbolic value for the entire crypto market, one symbol of the blockchain revolution.
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.
the gold situation is completely different from the bitcoin situation, eventually there will be something better than bitcoin and that is something inevitable that happens
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.
look to the future Is obviously there will be an altcoin that will surpass bitcoin, this issue of electricity consumption is a big disadvantage that bitcoin has, but in the future there will be some altcoin that will surpass bitcoin, it just needs to be some truly decentralized altcoin with an anonymous creditor is safe and does not waste electricity you will see people running to use this altcoin
