Bitget said roughly $350 million in cryptocurrency was stolen from its platform, highlighting persistent security risks across the digital-asset industry. TRM Labs researchers said attackers stole $2.9 billion in crypto across nearly 150 attacks last year, while authorities warned in July that organized crime groups use crypto to move funds rapidly across borders outside the mainstream financial system. Major thefts since Bitcoin emerged in 2008 include the record $1.5 billion Bybit hack in February 2025, the $610 million Poly Network attack in August 2021, the roughly $540 million Ronin Network breach in March 2022, Coincheck's approximately $530 million loss in January 2018 and the close to $500 million Mt. Gox thefts between 2011 and 2014. The incidents also exposed risks involving DeFi (blockchain-based financial services without traditional intermediaries), cross-chain transfers and online wallets.
