People usually circle out lots of criteria a good ico has to meet. Among them are nice website and introduction videos, good team, strong whitepaper, clear roadmap, big community, rich partners and the country of the project should not be from the Third world. I think that a website with a team, whitepaper and roadmap is a must have, but the most important things are the general idea of the project and partners willing to invest money in it. The second most important thing is the community that believes in the project and wants to help it develop. You should keep in mind, though, that only 10% of the ICOs make it to decent exchanges, so perhaps it is not worth the risks.
