Seeing the experience of this old man at Binance Square, all contracts were completely wiped out. I can't help but think of the difficult time I had in 2018, 2019, and 2020. At that time, the diaries were still kept in Impression Notes and Youdao Notes. I would take them out from time to time to remind myself not to get addicted to contracts. Many mistakes in life are caused by one's youthful recklessness, and only those who have experienced those difficult times may understand. There are many stories of sudden wealth in the cryptocurrency industry, but there are relatively few that ultimately lead to good results. That's why I have been repeatedly mentioning in the group chat that if I make money, I have to withdraw it. If I don't withdraw it, it's easy to return it to the market.
