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.
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.
Its the KING of all crypto which it isnt surprising that it would be staying on the top.If bitcoin did not exist then so as with altcoins that we do have today. Blockchain technology does really give out that
revolutionary kind of utility and Bitcoin did really make out that kind of possibility on having anonymous and decentralized kind of payment system.There might be lots of alts in the market which
do works better and cheaper but the community does know on where they would really be putting up their support.
