Crypto Loses $755M in Q2 2025's Worst Hack Quarter Ever
83 cyberattacks drained $755 million from crypto in Q2 2025, making it the most hacked quarter on record. Cross-chain bridges were the deadliest target.
If you're holding crypto right now, Q2 2025 just handed you a brutal reminder of why security still matters more than any price chart.

If you're using a cross-chain bridge or any protocol that aggregates liquidity across networks, you're operating in the highest-risk layer of this ecosystem right now. Audits matter. Protocol history matters. Chasing yield on a shiny new bridge with no track record is how you become a statistic in next quarter's report.
