First of all, altcoins should not be held for the long term, because as we know they have the tendency to collapse and disappear, second I think that at least since 2017 most forum members had learned that altcoins do not offer any utility at all, and while there are a few exceptions that is all what they are, and finally if despite those facts you are still thinking about taking the enormous risk of investing in an altcoin, then the hype behind a coin should be the main factor to consider, as only a coin like that has any chance of giving you any profits.
