We can't stop them from launching their ico because we can't know if their project is scam at the beginning. Some of the project that turns to scam has good whitepaper, website. Some of them deliver too their project but at the very end turns into nothing and just leave the project. I think the only way for us is not to invest on this and before that of course we need some information about their company and other way is to invest only what money we can lose.
