On my first investment in one ICO way back 2016, It was a failed since it was just my firstime and I'm not taking time to look or to read the whole information about that specific project. But loosing $30 was my turning point. From then, I started reading, investigating projects or ICOs which capture my interest though. And now I can say that I've learned since from the 4 ICOs that I've invested, 3 of them had gave me 70% of profit.
