My opinion is that altcoins are still dependent with Bitcoin. We can prove that by looking at the most recent bearish market. Bitcoin's price is also dragging down the altcoin market. Altcoins are still growing and maybe in the near future, there is a huge possibility that they will take control of the market. For now, I can conclude that Bitcoin is still on top.
Bitcoin still controls digital money. It is impossible for altcoins to go beyond the price of bitcoin, because bitcoin everyone knows about digital currency, blockchain and peer to peer transactions that have only known fiat money. Bitcoin is the flag carrier of cryptocurrency.
