If you're new to ICO's, make sure to be investing only in reliable projects. You can judge the credibility of one by checking the team behind the ICO, their LinkedIn profiles, previous job record, by checking whether the project is solving an existing problem, etc. For example, one such ICO which I'm following is AgentMile - a commercial real estate ICO.
