In February 2014, the world's largest Bitcoin exchange, Mt.Gox, lost nearly 850,000 Bitcoins, about 7% of the total Bitcoins, due to a hacker attack. The incident caused the Bitcoin price to plummet by 80%. Ten years later, I didn't expect that there are still more than 5 billion US dollars of Bitcoin in the wallet address of Mt.Gox. I really suspect that they were the thief crying "stop thief" and stole the money from the company. #门头沟事件
