first of all you should search the market thoroughly and select the best coin for your trading because trading in different coins will be more difficult for you because you do not know how to trade. Take some time with experts and try to spend as much time as you can in front of your computer so that you can observe the market regularly.
In fact, you should not even be trading so many coins than you can handle at once.
The thing with a lot of people is that they want to trade everything which is not a bad thing if they can, but monitoring those trades is where the problem then starts.
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.
