There is an ico from the Krypital team: Merculet. The project of this team was quite successful before: Cybermiles, Arcblock. Do you think this is a good ico? Should continue to join ico in the moment?
You should do a lot of research in the ICOs that you are joining. If you see that their plans are feasible and believable, then you might as well try. A word of caution though, be mindful of the ICO projects that you are joining, if you are convinced then you might as well try it but if members of the ICO program aren't active then you might as well leave and find a new one instead.
