They cant even bother to check out the projects, updates, developments and different data points before investing. Many investors in the crypto currency are just looking at the values, if they see it low then they just go on buying and once that starts growing then they are not having power to sell those coins immediately after getting some profits, but they will wait and wait and then it drops over the night and they loose. Thats what the greed is and thats how it eats you. Better be cautious and alert the same way when we buy at low!
