With the maturation of the crypto market, thankfully a lot of weak ICOs are being weeded out. With that being said, I think a key thing to ask for any ICO/token is; "Does this project need blockchain or a cryptocurrency, is it more practical to not be a cryptocurrency"?

Also a lot of companies have VC support, in theory this is a good thing but I have personally heard that a lot of VCs are trying to exit their earlier investments by having the companies they funded do ICOs.

Always do your research!
