Binance, the world's largest cryptocurrency exchange, has pledged to cover the $6.3 billion in client assets affected by a recent security breach, stating it has set aside over $6.3 billion of its own funds for this purpose. Approximately $3 billion of the stolen assets have already been frozen on blockchain networks. The exchange's initial investigation suggests hackers gained access to its withdrawal systems to make unauthorized transfers, but found no evidence of private key leaks. The incident highlights the risks of trusting exchanges with digital assets, with experts advising investors to research exchange regulations and consider self-custody for long-term holdings.
