Utility - this is basic usage of the coin to perform one role or the other in real world. e.g BNB etc.
Hypes:- this mostly happened in memecoins categories and a recent trends, this is just the dev team pushing the coin to investors face by way of aggressive social media promotions and hype's with zero user case or and working project to support their existence.
If you choose to invest in altcoins with hypes, then you should know that you are going to lose at the end. If you invest in them when there is hype, if the hype gradually goes down, then you should know that the coin which you invested in is also goin down, and at the end you going to hear that the coin is dead already, and you going to be losing your money, so investing in coin which have no use case, and are pumped base on hype is completely wrong.
If you invest in a coin with use case, you will know that even if the coin price drops, with time it’s going to bounce back, and you going to be in profit. Actually no altcoins are suppose to be trusted, but it’s better you invest in the one with use case if you want to invest in altcoins.
