In my own opinion, btc will take control of the market and well as the altcoins. If you will really look into the market, as btc goes high altcoins also follows, and as btc goes down altcoins also goes down. Btc and altcoins has connections on their different role. Btc is the only crypto currency that can exchange on different fiat money which other altcoins. Btc also got mass adoption which is very important on which coins will be known and not. Btc also made a great name in the field of crypto which everyone knows it now.
