Practice makes you perfect mate. What do I mean to say about this matter? of course, you need to apply actual trading and start with a small capital first. Then, observe the flow motion or chart of the price value depending on the coins you like to buy. Just never get hype with the people who will say to you regarding about this things. Because experience is the best methods for this matter for us to earn nicely in the end.
I agree more with your way, my friend, because learning better is by doing real practice and starting with the smallest nominal and always recording what makes the predictions that we do wrong and correct them. Usually with every mistake we make, it will be faster to remember and will not make the mistake again.
Of course, it is not wrong to also accept what is suggested by more experienced people, but it is also necessary to analyze it well because the movement will always change at any time.
