Trading is not as difficult as you think
It's easily said than done and a lot of traders only make profits with their mouth and not in reality. Trading theory is different from what you will see in the market because you are trading a volatile asset which the price is unpredictable. How much profit have you made from trading and which trading strategy are you using that makes you feel trading is easy. I want to know.
You are right trading is significantly more challenging to carry out in the actual world compared to how it is verbalized. It is easy to work out theories and strategies but when you put real money on the line things get more complicated due to emotions and the unpredictable in a game. Volatility can drive away any gains in a few minutes and even seasoned traders experience losses.
