If I was one of the people who bought BTC at $20k 2 years ago I'd probably still hold on to it and wait for it to fly high again. I'm too lazy to do some trading but if I do, that's probably one of my options to gain back my investment. Trading takes dedication so I'll certainly study about it first before investing, I don't want another loss of course. I am one of those people who are positive enough to trust Bitcoin that it will eventually bloom in the future.
Well as for the other question, I handle stress by doing house chores and probably playing online to make myself entertained and cool down.
