Yes, you are right, and I agree with you. We should have a skillful in trading, and if we feel that we don't have those skills, then we need to learn and never stop before we can master the skills. I am sure that every people can be a master in trading, but it depends on how he can learn more about trading and how hard he will learn.
We have a chance to make a lot of money from cryptocurrency especially in trading, but we need to have skills to trade so we could be able to make a profit.
Learning and practice as much as possible, that's the key to be successful trader. Although I'm not interested to be full time trader, but I keep on learning although I do not practice to much.
Skillful alone is not enough to make profit in trading imho, as the result will always based on how the market goes by. We need the skills to predict, but we also need the skills to prepare something unexpected.
