I'm a newbie and have been into crypto for a couple of months now. I must say the advice from other members about not checking trades too often is very good. One can become obsessed with it, and I think the thrill of the "win" can be quite addictive. Similarly that depressed feeling when the world is "red" can be deflating as well. There must be a "happy" medium, if one is to maintain a balanced life.
Don't invest or trade with your emotions else you can always have an imbalanced life where the paradigm will be shifted to a more troubling one. Invest and never be too greedy. Exercise patience and give some coins long term goal, go out, have some fun and come back to check in about a year's time.
