The moment you accept yourself as a trader. You should stick to your guts, stick to your plan. I know what seems to be the problem now. You are lack pf self confidence and you are indeed scared of any negative results. Make sure you are a risk taker if you want to become successful in trading
Always remember that you must go on with your decisions. If you are kinda hesitant with it, give a break. That is why I am always saying that stop loss is really helpful in this kind of situations (sideways and sudden pump or dump).
If you look at the history of all successful traders, they were like you in the beginning. No one is born perfect or expert, people learn all by the passage of time. But as you said, this is the major quality of traders that are ready to take risks but for you, I will suggest trading with potential coins which have history of generating nice profits in the past. Just stay positive and confident.
