There are a lot of tokens, many of them worth 0. The question is, why and which tokens will gain value in the longterm?
I'd love to buy a lot of coins, but many beautiful project doesn't need their tokens to release their products... I see a lot of tokens that have not use cases.. why should they go up?
I think you've said it yourself really. If a project doesn't need to be crypto, then there's no real use case for the token. Some need crypto by their nature, say for example smart contract platforms and IoT projects. One of the first things to ask when considering any project is: does this really need a token, does this really need to be crypto? If the answer is no, leave it alone. If yes, then there is plenty more to investigate regarding the use case.
