Bitcoin is the symbol of cryptocurrency. All other coins follow Bitcoin's volatility. When Bitcoin falls, other coins will surely fall. When Bitcoin rises, so do other coins. Bitcoin is the center.
Just by looking at the market capitalization on coinmarketcap, we can see that bitcoin's capitalization for over 40% of the total market capitalization, which shows the strength it is having. Yes, bitcoin is the cradle of the crypto industry and will always be the king of the market not only now but even in the future I don't think there will be a coin that can replace bitcoin, since the coin is currently generated from profit, there is no real utility or use case.
