What is the most tragic thing you have heard in the cryptocurrency world?

Last November, a friend of mine was trading contracts, starting with a principal of 500,000 and going long at 5 times leverage. At the peak, his account reached 4,300,000, and after deducting fees and some from hedging with spot trading, it was a total return of 851%.

If it were you at that moment, what would you do? Most people would have already cashed out, but he didn’t. His wife said there was a small dip in the middle, he didn’t stop-loss, and then it rebounded. At that time, the contract account's profit had already exceeded 900%. There were too many people shorting, and he didn’t pay attention. Later, it dropped a bit, and he still didn’t choose to stop-loss. His wife said that when it hit 430, he called her over with a slightly trembling voice to tell her about the situation, but he wasn’t particularly excited; instead, he just stared at the screen, incredibly calm. Because with contracts, he had previously made almost 3,000,000 at the peak and then gradually lost it all. Having seen many ups and downs, he remained extraordinarily calm when faced with this situation.

He firmly believed it would reach 500, wanting to wait until it passed 500 before cashing out. As a result... without hedging the contract position, a sharp needle came down mercilessly... The account was instantly left with just over 80,000, almost 90, and it was clearly too late to close the position... The outcome, as everyone knows, was tragic.
