Yes I believe, because wether we like it or not, bitcoin has disadvantages , like higher fees, sometimes transactions delayed, slow transactions compared to the other altcoins today and etc. I believe that there will be a new coins called to be like more upgraded bitcoin.

Crypto world is like an NBA game, Imagine bitcoin is Michael Jordan, he is an NBA legend, but he is not an alone legend forever. Later on there is Kobe, James and so on
