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.
If we are look at the market every time we can learn more about the flow of the value of each coin/token and also we can avoid in panic buying/selling if we know a little about the flow of rise and fall.
