Yes trading is not a game because see trading involve high risks and ofcourse it is not suitable for all investers. Before making any investment decisions, we should have a lot of knowledge about it . Because if you are trying to invest money without knowledge then your money can go into loss.
You're right. Most often, the majority have problems due to the wrong attitude to trading.
Many beginners treat this too simply, as a game, not realizing the risks and the fact that for success in trading it is necessary to spend a day at the monitors studying information and quotes.
Not taking trading seriously will result to a bad one and this is also why many newbies suffer into depression when they lose all their money, they thought trading is easy because they are just following the hype and the trading signal. This is not a game that you can easily play again, your money at stake here so treat trading as your regular job where you need to work until you master it.
