first of all a person need to brave enough for being a trader. Afraid of losing money can't let you be a good trader cause trading can't be imagined without risk and There's no doubt that everybody can be a trader and i already exprience that. I learn some trading skill and started trading and most of time i did loss in trading. Then i realized that, trading isn't that much easy. Without proper learning, a person can't make profit from trading but loss his money
Of course, someone must be brave to take the risks in trading when he decides to do it. Trading isn't an easy matter, it requires sufficient knowledge and experience. But sometimes this also doesn't guarantee profits, we still have a chance to lose money. So, a person never joins trading if he isn't brave enough.
However, I think a person also needs to be smart if he wants to be a trader. That's why knowledge has a crucial role here. Only smart traders who can get profits in any condition of crypto market. If a trader isn't smart, it is difficult to get profits due to an easy change of trends in crypto market.
