I think that diversification is the key to success. It is better not to invest all your funds in one coin, even if it is bitcoin.
Considering how many shitcoins are out there, I don't even want to bother any other altcoins for now. My gray line for interacting with altcoins would be any forms of short-term trading - call it day trading. I had risked way too much for altcoins before and good thing I did not even bother investing in meme coins.
I am not even going to do the same even if I went back to the past like when Musk was a hot topic in crypto.
I think a better set-up would be like this> 80% for BTC and 20% for ETH but I prefer this set-up better> 100% for BTC. No need to waste our money, time and effort on other cryptos because all of them are only depending on Bitcoin. If BTC falls they also fall although if BTC pump they will pump but I think our profit potential is still the same or have gotten lesser than if we put all our of money in Bitcoin.
Many projects are only promising at their earlier runs but once they dump they will hardly recover anymore so don't ever mistaken their dump as a good opportunity. We are not holding for no reason but all of us are doing it because we want to earn a massive profit.
I was similar to that kind of setup before until alts arrived at its bearish season. I went 100% BTC and I am not going to bother doing any portion of alts for now. Even if the one you said about following the price of Bitcoin is true, it's way too risky for me.
