You sound confused Callido - like you are trying to find a reason to fuck around with shitcoins and/or to give them more credit than they deserve.
When you think about correlation, it is better to think of bitcoin as king daddy rather than trying to suggest that bitcoin is correlated to shitcoins. It is like you are trying to say that the tail wags the dog, when if you know anything about dogs, you realize that the dog wags the tail, and in this case bitcoin is the dog, not the tail.
Essentially all shitcoins are dependent upon bitcoin's success in order for them to have any kind of chance of having any kind of market. Sure various shitcoins can pump and dump based on their independent factors too, but if you cannot recognize that bitcoin is the leader in the space and that all shitcoins are correlated to bitcoin, then you are likely lost, and you have not yet figured out what bitcoin is.... which I think it would be better for anyone trying to dabble with bitcoin and/or with shitcoins to learn about bitcoin first, yet there are so many shitcoiners who don't even really realize what bitcoin is, since they are so wrapped up in their various little crap token ecosystems and even falsely concluding that they are independent from bitcoin and various other kinds of blah blah blah to pump their nonsense.
Don't get me wrong, I am not proclaiming that shitcoins are going to be going away anytime soon or that there might not be some potential valuable developments that happen in shitcoins that end up either getting ported into bitcoin or to allow for bitcoiners (or bitcoin developers) to learn what not to do. The mere fact that there might be some back and forth learnings or even some monetary affects that come from shitcoin pumping and/or dumping on bitcoin does not mean that bitcoin is all of a sudden dependent on shitcoins for its ongoing existence or the ways that it grows or fails to grow.
Get involved in shitcoins with your time, energy and money at your own peril, and hopefully you don't get too distracted into that crap.. so maybe if you limit any kind of investment that you put into shitcoins to less than 10% of your bitcoin investment, then at least you will be going down the road to prioritizing the right thing, ie bitcoin.
This is a well-detailed response to clarify @Callido thank you. It's best if we all know who is superior to others and in this case, Bitcoin is superior irrespective of shitcoin being depended on it. Bitcoin movements indeed tend to affect shitcoins but there are times when Bitcoin goes down and then some shitcoins still manage to retain its price or go up. Apart from Bitcoin, other factors affect shitcoin and that shouldn't even be discussed here.
Sometimes people need to be taught a lesson by themselves so that they can realize their mistake and stop thinking investing in shitcoins is a way for diversification. Meanwhile, it's just a distraction that keeps them away from staying consistent in their Bitcoin investment. If they want to make money quickly then they stop deceiving themselves of Bitcoin investment and go astray with shticoins.
It's so sad that we can guide people but anyway, they will still make their own decisions. As long as people think they can get rich quickly there will be shitcoins everywhere. Fuck it!
