No one word answer to this one.

While ICOs allow for easy dump schemes, there are some genuine projects. Essentially it is a situation where amidst a largely negative dominated ecosystem - there is the small, but relevant, amount of positive projects depending on the existence of that ecosystem for vitality.

I would advise you to do research on a case by case basis and just look at individual ICO projects and try to apply something like Charlie Munger's two-track analysis when making a decision.
