Hah, that is interesting topic, and you can learn from the others mistakes. So, few months back i invested in one ICO, and for 3 months i earned 10x of my investment. I couldn't believe it, i started thinking that is fake, or it would be hard to get the real money, but i did succeed and i am very happy to have such an experience, positive. From now long i research for another promising ICO's and hope to get lucky again.
