Binance’s $6.3 billion hack raises questions about crypto wallet safety

Two high-profile security breaches this week – including the biggest cryptocurrency theft in history – are raising questions on the safety of storing funds in a wallet on a crypto exchange . A security incident at digital asset exchange Binance on Thursday affected some $6.3 billion in client assets, making it the largest crypto theft on record. Earlier that day, prediction market platform Polymarket temporarily halted trading on its international exchange after a third-party data provider was hacked, resulting in at least $2.7 million being drained from users' wallets. The company's international platform operates on the Polygon blockchain.
