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 is a currency that was invented in 2008. This currency has been used in the market for a number of years. Recently, the Crypto Bitcoin option has discovered some more currencies, which are operating in the current market, among them, a currency of altcoin. altcoin has become quite popular in the current market. But Bitcoin is the best in crypto currency market and its price is high.
