A trader should know himself or herself better and act accordingly.
I mean, if you are prone to getting nervous about every market movement or event, you better stop reading the news and checking the price of your coin every second.
Take a deep breath, shut down the computer, and take a long walk in the park. Don't forget to eat adequate and well-balanced diet and get enough sleep and you're gonna be okay. Otherwise, the trouble is lurking around the corner. You know what I mean.
But if a trader has sold his house, and a car, and a garage, quit his or her day job and invested all of his or her assets into crypto, the best thing they can do in a situation like that is shoot themselves in their mouth rather than go visit a website for relaxation.
