I think Bitcoin is the currency that determines the survival of the Altcoins. If Bitcoin prices are high, the Altcoins will go up and when the bitcoin drops, the Altcoins will go down. This shows that Bitcoin is the brain cell of the Altcoins and even the ICOS campaigns that exist are also highly dependent on Bitcoin. The problem to be solved that Altcoins can be separated and not affected by Bitcoin. It is very difficult for all.
