If you find that your knowledge has not peaked so you can self-enrich or you can trade but lack confidence you can re-learn how to trade for success.
There is no end to learning as long as we are still living in this world because even those who have been successful through trading are still learning by using more of their time in order to remain successful in the long term. Trading can be used as a daily job for everyone and to reach the peak of knowledge there will never be an end to learning. Because conditions of increasing prices are not always visible in the market, so even in conditions of decreasing prices, everyone must learn to take the right attitude so that work does not stop just because of a decrease in prices.
Yes I agree with you trading is such a subject that there is no specific study in books that you can finish reading. To learn trading you need to read every day, the more you read the more knowledge you gain. To be a skilled trailer you must patiently analyze the coin, understand whether the coin is tradable or not. I cannot learn you in a day or two, those who are skilled in trading have been trading for a long time and there are many who have not been successful in trading for a long time. However, you will only succeed in trading when you can control everything else or you will be fail.
