I think that btc is the best coin ever and it will be able to win the market and remain the leading currency forever, to my mind, it is fair because btc is the best coin in terms of confidentiality
I also have the belief that bitcoin will continue to lead the market in the future, although sometimes there are problems that prevent it, but still bitcoin will still lead. because bitcoin is the first coin that appears and has helped the lives of many people. so sometimes another coin is difficult to beat bitcoin.
Bitcoin itself is the definitions of this market, even there's already a lots of alt project bitcoin remain to be the actual basis, the market will follow from where bitcoin wanted to move the market, the dominations still exist and lots of people already gained interest and start investing with this crypto money,
incoming years we will see how far bitcoin will go and how much valuable it can be.
