We cant assure its safe or not but if you make some research, analyze every single details in there (program,whitepaper,roadmap, dev's willingness) there has a chance to find a good ico . If you are a investor of ICO you always need to monitor the price of the token that you bought so that you will not lose your capital especially if the price goes down . For me its better to participate in bounties rather than using my money in some ico .
