There is no way that he would be able to learn everything that he’s meant to know at once. The main important thing here is for him to learn the basics and start, as time goes on he would get to have some experience that would help to better his skills, and also make things easier for him.
it's very obvious that learning has steps. And it's a measure you will take accordingly, i believe that manual tutorial of trading will give more courage than using virtual kind of lesson to comprehend all the basic things of cryptocurrency trading at a time. Even though someone learn and master trading according to its teachers direction or instructions, and without continuous practice, i don't think whatever you acquire during the time of lecture will be effective.
I think that's the reason why theory and hands-on practice are so important and should be done,
because when we only learn about theory, it is clearly different from us trading directly in the crypto market,
so we have to practice as well to gain as much experience as possible
