There are just too much good coins these days and are very innovative than BTC.
BTC however still may continue to be the number one because of its adoption, everybody knew about BTC and all these people probably never heard of Dash or ETH which is only familiar to people in the cryptoworld like us. I have been here in the forum for years and I don't hear anything about Santiment actually which ICONOMI had invested. Certainly BTC is on the losing side, they have to do something to save it or we lose satoshi.
