I would say, those who are even not rich and have no commitments, would certainly have less stress and can invest in bitcoin and hold them peacefully without much stress. I have personally experienced it. When I had a commitment and was expecting a turn over from trading, really I had to either sell them off at low profit or at loss. But when i did not have commitment, I peacefully held the orders and sold when only the trend was up.
investing money that used in your daily needs would make you hard to hold it in the long term, avoid this and you'll be a real hodl-er to feel 1000x return.
otherwise, you'll stick in your chart to check where is your position and before even its reaching 10x , you'll just withdraw it on 2x or 5x at tops!
even if a rich guy with 100m in wealth and invested 90% of his wealth wont resist to see his investment gained 5% to cash them out, there's no real hodl-er unless if you are in strong believe or what so called commitment as you said.
