Binance said Saturday that company-funded token purchases had replenished 90% of the cryptocurrency stolen in a record $6.3 billion hack. The remaining 10% consists of less liquid tokens, which may take longer to buy, Binance said. The U.S. Federal Bureau of Investigation attributed the attack to TraderTraitor, a North Korean state-sponsored group. Co-CEO Richard Teng promised that users would not suffer any financial losses. Binance suspended withdrawals after the attack but said they were still scheduled to resume on Sunday.
