How can you make sure you invest if it is safe? It is difficult to choose who is legitimate or scam because we know that we have news on people that many of the ICOs are scams so it's best to first share the projects so we can make sure we earn tokens in every project.
Well, for one, you need to make sure to do enough research to know if the people running the Ico are legitimate business people. Too many ICO are simply developers with a desire to make something. I always look for a business plan and the business background to effectively implement that plan. This can be true for both coins and tokens. In the end, if it sounds to good to be true then it probably is.
