The largest loss case in history possibly caused by personal negligence When I told my friends outside the industry as gossip about the case of losing 50 million U in fishing due to dust poisoning today, he reminded me that this may be the largest case in history where an individual user suffered the greatest loss due to a small negligence. Plus, Wang Chun @ satofishi, who saw the fish pond, said that he used 500 BTC to fish last year to verify if his private key was leaked, and ultimately lost 490. It is still worth 43 million dollars now. The brain circuits of wealthy people are quite peculiar - what's the difference between this and trying a lighter to see if the gas leaks? This has sparked some interest in me. How much trouble (how much money) can a momentary negligence cause in human history?? After searching, if a small restriction is added, it seems that today's owner can really rank first. The condition is: -If it cannot be retrieved (including hacker refunds) -Excluding institutional losses (where the losses are incurred by the institutions involved) Now the owner has written a strongly worded letter to the hacker demanding a refund, not a request, but a threat, which is the most domineering I have ever seen I don't know if I can recover the loss. If restrictions are not included, there are also some cases with larger amounts. ~~~~~~~~~~~~~ ☘️ BTC whale caught fishing In fact, last year (May 2024), a giant whale suffered an almost identical "address poisoning" attack and mistakenly transferred 1155 WBTCs (worth about $71 million at that time) to hackers. Fortunately, with the intervention of security companies and on chain detectives, the hacker ultimately refunded the vast majority of the funds. ☘️ Mizuho Securities' Golden Finger In 2005, a trader originally intended to sell one share of J-Com company for "610000 yen", but ended up losing by hand as "selling 610000 shares for 1 yen". The company suffered a loss of approximately 225 million US dollars (although it was a company loss, it was a single personal operational error) ☘️ BTC that cannot be retrieved James Howells and his landfill hard drive are already well-known stories in the industry. In 2013, British engineer James mistakenly threw a hard drive containing 8000 Bitcoin private keys into the trash bin while cleaning his home. This hard drive is currently buried deep under tens of thousands of tons of garbage in a landfill in Newport, Wales. If it hadn't been disposed of, I estimate he wouldn't have been able to get it now, but the book loss is 700-800 million US dollars. Former Ripple CTO Stefan Thomas stored 7002 Bitcoin private keys in an encrypted IronKey hard drive, but he lost a note with the password written on it. The hard drive only has 10 attempts, and he has already made 8 mistakes. If the password is not cracked, the money will be there, but he will never get it. ~~~~~~~~~~~ Of course, the most incredible thing is that there are still people who are unaware of common dust poisoning attacks and do not need to sign multiple wallets to manage such large fund transfers. Let's not sprinkle salt on other people's wounds for now. Perhaps wealthy tycoons like to be so unique.
