Internet reports that TechCrunch founder Michael Arrington said that Coinbase's recent data breach may pose a serious threat to users 'personal safety. He pointed out that the leaked information included users 'home addresses and account balances, which could make high-net-worth cryptocurrency holders targets for criminal acts such as kidnapping. Arrington emphasized that regulators should reassess mandatory KYC (Know Your Customer) data collection policies and called for criminal accountability of executives who fail to properly protect customer information. Balaji Srinivasan, former Coinbase chief technology officer, also pointed out that state-mandated KYC data collection may be the root cause of such risks. Coinbase previously disclosed that hackers tried to extort US$20 million in Bitcoin after an overseas customer service employee took bribes to leak user data. The company refused to pay and offered a reward for the same amount to pursue the criminals, while promising to compensate affected users. The U.S. Department of Justice has launched an investigation into this. Balaji Srinivasan, former chief technology officer of Coinbase, pointed out that the fundamental problem lies in the government-mandated KYC data collection system.
