Binance is investigating a potential security breach involving large transfers that founder Changpeng Zhao described as looking like a hack. In response, the exchange suspended all deposits and withdrawals and began working with law enforcement and industry partners.
To mitigate the fallout, stablecoin issuers Tether and Circle froze over $2.5 billion in funds. The news of the incident led to a dip in the value of Bitcoin and Ethereum.
