Carl Agnelli, head of security at a16z Crypto, warns of increasing personal security threats such as kidnappings and armed robberies targeting crypto founders, engineers, and investors. Drawing from his 35 years of security experience, including 25 years with the Secret Service, Agnelli outlines key strategies for personal safety. These include maintaining a heightened state of awareness, safeguarding personal information, and adopting daily security habits like minimizing distractions, informing others of travel plans, carrying non-lethal defense tools, and familiarizing oneself with exits. Agnelli also suggests crypto-specific protective measures such as setting up secondary wallets, reducing digital footprints, enhancing home security, diversifying assets, and preparing emergency and evacuation plans. He emphasizes that while crypto technology cannot protect against physical threats, prioritizing personal safety is crucial.
