I don't think altcoins can survive without btc, so I think the price of btc will continue to affect the price of altcoins.
some examples have been seen when an altcoin is rising, then the btc price suddenly drops, the altcoin will also immediately fall.
I agree with you, because Bitcoin is the main foundation in cryptocurrency, so of course the price of Bitcoin greatly affects the price of altcoin, therefore Bitcoin price movements will affect market conditions, so therefore 50% more of my assets in cryptocurrency are in Bitcoin, because Bitcoin is the best investment for the long term and definitely give me profit.
the main parameter in cryptocurrency is bitcoin, and as if movements in the cryptocurrency market are based on bitcoin movements, therefore I myself am also penalized if altcoins can survive if bitcoin dies. Of course, if bitcoin dies, it means that the cryptocurrency market will also die. Many investors will not believe it, which will eventually impact altcoins. bitcoin is like a king in the cryptocurrency world, and if the king dies then his troops will run topsy-turvy
