If technology is concerned, bitcoin really has an outdated technology platform. Currently other altcoins such as CS, ETH, EOS are altcoins with a good technology background and very fast transaction speed, transaction fees are much cheaper than BTC.
But speaking of the future, I believe that BTC is still in use and will still hold the top position.
of course all rang will still be using bitcoin. many coins do indeed already have better technology, but the main one is bitcoin we know it all. bitcoin will look at developing future and bear witness to the development of the bitcoin.
