It's traditional market nonsense. Crypto according to them holds no intrinsic value, so you are trading something that doesn't really exist or creates anything. I don't think many people are shocked by that nonsense anymore. The only minor difference is that the crypto market operates 24/7, where traditional markets are tied to working hours, which may grant people a well needed break if they are overly stressed. In the end you are responsible for your own actions where you should take a break in case you feel tired or stressed. Being tired and stressed only works against you when it comes to trading, so the logical solution is to stop and do something else. Common sense.
