Operational Security (OPSEC) for Crypto: Don't Become a Target

Large crypto holders attract targeted attacks. Here is how to use OPSEC principles to prevent yourself from becoming a victim.

Operational security (OPSEC) is about protecting sensitive information from falling into the hands of those who could use it against you. For crypto holders with significant assets, careless information sharing creates real physical risk. People have been robbed, kidnapped, and extorted specifically because they publicly disclosed their crypto holdings.

Information You Should Never Share

• Your crypto balance: never disclose the value of your holdings on social media — this makes you a target
• Your hardware wallet: do not share photos or mention owning one — implies significant holdings to a specific physical device
• Your home address in combination with crypto holdings: connecting these creates serious physical risk
• Your exchange accounts: the fact that you use specific exchanges and their approx balance
• Seed phrase locations: never, under any circumstances, to anyone

OPSEC Best Practices

• Separate online personas: use a pseudonym for crypto activity separate from your real name
• Device hygiene: dedicated device for large crypto operations — not your daily use device
• VPN for sensitive operations: hide your IP from crypto services when managing significant holdings
• Meeting security: if you must meet someone about a crypto transaction, do it in a public place
• OSINT audit: Google yourself + your wallet addresses to see what information is publicly linkable

Physical Security

For holdings above £50,000: consider that your address is potentially linkable to your crypto activity via OSINT. Install quality locks and security cameras. Do not keep hardware wallets in obvious locations. Tell your insurer about crypto assets (some homeowner policies exclude crypto theft). For ultra-high-value holdings: a safety deposit box at a reputable bank, and potentially a separate apartment for daily crypto operations away from your primary residence.
