TL;DR After analyzing 20 major crypto theft cases, we’ve distilled the top three key patterns and practical tips for everyday users to avoid pitfalls Key patterns from 20 theft cases: 1️⃣ Technical vulnerabilities account for the majority of cases, but the losses per incident are relatively limited. On the other hand, permission and social engineering attacks are fewer but contribute to the bulk of total losses. 2️⃣ Permission-based attacks are scaling up—among the 20 cases, the four largest loss incidents were all linked to North Korean hackers. 3️⃣ The battlefield for technical vulnerabilities is shifting—cross-chain bridges have never been truly secure. 4 must-know tips for everyday users to avoid pitfalls: ✅ Don’t concentrate assets in a single protocol. Diversifying storage won’t eliminate risk entirely, but it can cap the maximum loss in a single incident. ✅ Keep your distance from new protocols. Most technical vulnerabilities are discovered in the early stages after a protocol’s launch. A protocol that’s been running for two years, undergone multiple audits, and survived real-world stress tests is far safer than one that offers high returns right after launch. ✅ Check if the protocol is genuinely profitable. Look for protocols that generate real revenue—they’re more likely to have the ability to compensate users in case of losses. Protocols that rely solely on token incentives and lack real income often resort to issuing new tokens or making empty promises when things go wrong.
