Just choose the altcoins that you know and believe will someday grow or as you've said, the prominent ones. We've got a lot of them and it's your choice on which is going to be your pick. There's lesser risk with them and that's gonna make you like Bitcoin because it's always been the stable crypto in the market. Stable in that sense that you've got assurance that it won't be rugpulled unlike the choice of many folks today, meme coins, NFTs/tokens, etc. Too rampant in that scene.
Other altcoin might likely do well but it just depends on the project and it's best to be careful not to be a victim to some random scam project, investors still buy memecoin for long term investment in my opinion I think they're taking a big risk and the funny part is a lot of them know much about new memecoin but they get deceive by others testimony, it's always good to choose bitcoin for long term to avoid stress, the reason why a lot of people still deal with shitcoin they've refuse to make research they just choose to take risk always, when dealing with shitcoins there's no guarantee of making profit, it's likely that newly investors are the ones who always fall victim to such investment that's why newbies who can't differentiate between scam project and real project they should just choose bitcoin.
That's totally a big risk for them. They have tasted the profits with these meme coins and I think that's why they're still into it and can't stop buying more of it because of the potential that they see. I think that's totally fine on their end and all they need to do is to keep checking the memecoin they've bought so that they won't be a victim of a scam because there are too many altcoins nowadays that are scams. If they're not alert with it, they're going to lose a lot money compared to the amount they've profited.
