maybe impatient to be the main reason people fail, I don't understand maybe they are not real investors because in the stock market you need time to get profits those who play there should understand how investing works, most of the failures are those who try their luck without having sufficient knowledge.
Or because people still live in 2017 and dream to earn a lot in short time. They still cant let go the time when each invested during ICO (usually 2-4 months duration) dollar brought them five.
True, they are not real investors, but more like a lottery participants. Scratch cards is what they need instead of investing. Or they never had enough funds for a living. They cant afford long term investment.
