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?
All the decision depends only in you. But if you're asking an opinion you better continue joining ICO if you failed before then accept it. Failure is indeed oart of success.
If you quit because you failed then you don't deserve success ..
