Bithumb accepted the loss, acknowledging it was unrecoverable, with actual losses around $10 million USD. However, a user of another exchange wasn't so lucky. In May 2021, an Australian woman only wanted a refund of 100 AUD, but an employee accidentally entered her bank account number into the "amount" field, directly transferring 10.5 million AUD to her. She and her partner thought they had won the lottery and went on a buying spree, purchasing luxury homes, cars, and artwork, and even transferring the money to relatives and friends. The platform only discovered the fraud during an audit seven months later and quickly filed a lawsuit to recover the funds. The court froze assets, forced the sale of the property, and recovered most of the money. Ultimately, the man was convicted of theft and sentenced to three years in prison, while the woman was placed under community corrections. A classic example of a "windfall" scheme backfiring: money in hand isn't necessarily yours. But slow risk control is even more fatal 😂 These two exchanges are also showing signs of collapse. Their distribution systems should set limits for different cryptocurrencies and add more automatic verification and alarm mechanisms. Hopefully, all platforms can learn from this lesson.
