When I am putting my money into something, I need to be sure of my investment asset. I do thorough analysis of any coin be it ICO or not before investing. When it comes to ICO, reading and understanding whitepaper that have a detailed explanation of the project along with future projection is very much needed. I always make sure that the project I am investing in is clear to me. If I don't understand whitepaper, I simply don't invest. An important part of investing is that always invest in something you understand.
