What you say is not bad. But when an asset exists only for speculation, it is not good. In this case, we need to avoid such assets.
And why else should an asset exist for it to be good?
It is an asset that has a fundamental component.
In crypto, this is a team. These are people who are working on their idea, for the realization of which they sold these assets to investors. We all know that after the end of ICO/IEO project activity naturally

decreases.
Naturally, without a team, an asset is not interesting for speculators in general. The question is what makes an asset good.
