in my opinion bitcoin and altcoin can both provide profits in the future, and I think it's just a choice, bitcoin is a priority investment for every crypto user because bitcoin has great potential and is very promising, while altcoin is an option that can give you additional income.
bitcoin has become a safe haven for big investors because the amount cannot be reduced or added to, this is what makes bitcoin continue to be at the top while altcoins were deliberately created for business so not many can survive well, just look at it like meme tokens or other new projects, the majority of which end up being scams
therefore, for those who diversify their portfolio, I suggest making the investment portion in bitcoin larger than in altcoins
