Trading encompasses a lot of things and not something one can learn in just a single day which is where I think a lot of people usually do not get it. As long as you can learn, and practice slowly to gain experience and confidence by learning from your little mistakes afterwards, the better one gets.
Yes trading concept is easy just buy low and sell high but the main concept is when to buy and what coins to buy, especially in crypto trading even experience people will do a lot of mistakes. So don't rush to make an immediate profit, take some time and invest small amount practice more when you will get full confidence then trade with a big amount.
