People tend to 'run away' from trading because it somehow intimidate them. We know that trading is complex and maybe several of us knows that there's an under lying difficult concept of it. Other reasons are: (1) They lose too much money. (2) Not enough skills to fully understand and continue doing it. (3) Emotional.
They thought it is just that easy.
Most of the people I know don't want to take the risk and they think they could easily earn money with a small period of time with not that much knowledge about it. Investing in Bitcoin and other cryptocurrencies is not that really easy since we are dealing with a volatile market. If you will never adjust to this, you will never be able to have some good profits in the near future. We need to be patient, trading and investing is not that easy.
