I agree with you, it is not enough to just gain knowledge but to use that knowledge skillfully through the right strategy. Trading is a place where if you don't do everything right, you will definitely lose, trading is much harder to do in reality than to watch. Those who learn consistently and gain new experiences and lessons from every loss, are the ones who can eventually become skilled and successful traders.
Skilled and successful traders are traders who have indeed been forged with various experiences when they are in the market because they must have felt losses and also been made to wait for months without getting any profit because the crypto assets they bought have not increased in price. So that such things have become an experience for them and can make their mentality strong enough in the future, because patience after having more knowledge and strategies must also be in a trader. Because being successful always requires a process and more maximum effort without complaining with various reasons.
That is the reason why experience is called the best teacher in anything, nothing is impossible especially to achieve success if for example the person can really learn from experience by evaluating every mistake that causes losses, although I have not achieved success but that is how it should be because knowledge and science are the keys to success in trading. Trading is not about luck but about how serious, how strong and how consistent you are in learning to continue to grow, meaning that those who fail are those who cannot pass that phase.
