You know it's important to filter out the altcoin you don't need to the better ones moreover newly listed coin in the space some of them can't be trusted neither are they reliable to hold for long instead I will always encourage people to have bitcoin in your portfolios. Apart from Ethereum and BNB, Polygon and few other coin I didn't think people should hold irrelevant coins in their bags since they aren't worth holdings  and they are also being driven by Bitcoin price and whenever the price goes down it affects all every coin that depends on bitcoin for growth.
