many people have high IQ but not all of them are trading.
so, my question is "Whether high IQ it will affect the accuracy of one's decision making because to do Buy and Sell required the right decision-making, extensive analysis and detailed graph reading".
Yes, of course it is but I would not say that person with lower IQ is not having any chance, I would just say that higher IQ is a higher chance to be successful in any sphere of your life including cryptocurrency trading.
