In recent years, physical attacks on cryptocurrency holders have surged dramatically. According to data tracked by Bitcoin security expert Jameson Lopp, reported physical attacks on Bitcoin and crypto holders increased by 169% in just six months in 2025, with dozens of violent incidents including kidnappings, home invasions, and armed robberies.

Lopp maintains a comprehensive list of over 200 known physical attacks since 2014, ranging from $5 wrench attacks (where attackers use physical coercion to force transfers) to organized kidnappings involving torture.

As a crypto whale — someone holding significant digital assets — you are a high-value target. Criminals know crypto transfers are irreversible, making you more attractive than traditional wealthy individuals. Beyond digital hacks, threats now include real-world violence and sophisticated scams like pig butchering that can lead to doxxing, luring, or physical meetings.

This article focuses on physical OpSec (operational security) to maximize privacy and safety in everyday life, drawing from best practices recommended by experts like Lopp and security firms.

The best defense is not being targeted in the first place.

• Never discuss your crypto holdings publicly, at parties, or even with close friends unless absolutely necessary. Loose lips lead to targeting.

• Avoid all visible signals of wealth or crypto involvement: No Bitcoin bumper stickers, conference lanyards, luxury watches/cars that stand out, or social media posts showing opulent lifestyles.

• Dress modestly, drive common vehicles, and live in unassuming neighborhoods. Blend in completely.

• Remove online traces: Scrub old posts, use pseudonyms, avoid linking real identity to wallets or addresses.

Your residence is the most likely attack vector.

• Install layered physical barriers: Reinforced doors with deadbolts, shatter-resistant window film, motion-activated floodlights, visible security cameras, and alarm systems monitored 24/7.

• Create natural deterrents: Thorny bushes under windows, fenced property with locked gates, no easy climbing points.

• Build a safe room (panic room) with a solid-core door, independent communication (satellite phone or hardline), supplies, and a weapon if legal/trained.

• Store seed phrases and hardware wallets in bolted safes or bank safety deposit boxes — never all in one place.

• Consider professional security assessments or guarded communities if your holdings justify it.

The classic $5 wrench attack — where an attacker threatens violence until you hand over keys — cannot be fully prevented, but it can be made impractical.

• Use multisignature (multisig) wallets requiring multiple keys from geographically separated locations (e.g., different cities or countries). Even under duress, you physically cannot comply quickly, forcing attackers to keep you hostage longer and increasing their risk.

• Distribute keys/backups across trusted family, institutions, or secure vaults in multiple jurisdictions.

• Avoid “duress PINs” or decoy wallets — attackers may test them or continue violence if they suspect more funds.

• Consider collaborative custody services (e.g., Casa, AnchorWatch) that add institutional keys and emergency lockdowns.

• Vary routines: Routes to work, gym times, etc. Predictability enables ambushes.

• Maintain situational awareness: Head on swivel, avoid phone distraction in public, note tailing vehicles/people.

• Travel low-key: Use rideshares or rentals instead of personal luxury vehicles; fly commercial in economy if possible; never post travel plans in real-time.

• For high-risk areas (e.g., certain countries with known crypto kidnappings), hire executive protection or avoid altogether.

• Carry minimal identifying info; use burner phones for sensitive communications.

OpSec often comes into play in public settings. For example, if members of your team are discussing work-related matters at a nearby lunch spot, during a conference, or over a beer, odds are that someone could overhear. As they say, loose lips can sink ships, so make sure you don’t discuss any sensitive company information while out in public.

A lot of OpSec missteps can be avoided by being more aware of your surroundings and the context in which you are speaking: what you’re saying, where you are, who you’re speaking to, and who might overhear. It’s a good idea to go over the “no-no’s” for your specific company during onboarding and to remind employees of them periodically.

Many physical attacks begin with doxxing via scams.

• Phone scams / SIM swapping: Use authentication app 2FA (not SMS), put PINs/passwords on mobile accounts, screen unknown calls ruthlessly, never give out verification codes.

• To lock down your SIM, contact your mobile phone carrier. That is a standard that has been tested by telecommunications operators in the US, the UK, Poland, and China — also check out this tweet and this article. You just need to insist on it or visit the head office, and I’m sure that the support manager on the phone mayn’t know about it! Ask them to NEVER make changes to your phone number/SIM unless you physically show up to a specific store with at minimum two forms of identification. This (should) prevent hackers from calling up AT&T or T-Mobile or Vodafone, claiming to be you, and asking them to port your phone number to a new phone.

• Pig butchering: These long-con scams build fake romantic or friendship relationships online, then push “lucrative” crypto investments on fake platforms. Red flags: Unsolicited contact on dating/social apps, rapid affection, steering conversation to crypto, pushing specific (fake) platforms.

• Rule: Never invest with or send crypto to anyone you met online. Period. If someone disappears when you refuse to invest, it confirms the scam.

• General rule: Any unsolicited investment “opportunity,” recovery scam, or urgency play is fraud.

Get countermeasures in place. The last step of operational security is to create and implement a plan to eliminate threats and mitigate risks. This could include updating your hardware, creating new policies regarding sensitive data, or training employees on sound security practices and company policies. Countermeasures should be straightforward and simple.

We’re talking home invasions with intruders posing as delivery drivers (San Francisco $11M robbery on Nov 22), street kidnappings (Bangkok, Bali, Ukraine), carjackings forcing on-the-spot transfers (Oxford), and straight-up torture/murder when victims can’t or won’t pay (Dubai double murder, multiple Russian cases). The pattern is clear: organized crews are now routinely use delivery disguises, follow targets from public places, grab people off the street, or hit homes with overwhelming force and torture.

The threat model has upgraded from opportunistic thugs to professional kidnapping rings.

2025’s #1 new vector is criminals posing as FedEx/Uber Eats/Amazon drivers.

• Never accept unsolicited deliveries. Route all hardware wallets, seed backup plates, anything valuable to PO Boxes, private mailboxes (e.g., UPS Store), or secure coworking spaces, or lawyer/accountant offices.

• Install a package locker or secure drop box outside your perimeter that doesn’t require you to open the door.

• Use doorbell cams + intercom. If a delivery person shows up you didn’t order, do not open the door — ever. Tell them to leave it outside the gate or return later.

• Bonus: Have mail forwarded through re-mailing services (e.g., Traveling Mailbox or Earth Class Mail) so your real address never appears on anything.

Most victims who got hit hard were doxxed through basic OSINT.

• Pay for professional deletion services (DeleteMe, Kanary, OneRep, or 360 Privacy) — do it quarterly. The average whale appears on 70–120 data broker sites with home address, phone, relatives, property records.

• Remove your home from Google Street View (request blur) and Zillow, Redfin, etc.

• If you’re really paranoid (you should be), buy your next house through an anonymous land trust or Wyoming/LLC structure so your name isn’t on public property records.

Decoy wallets are good, but pros now expect them and will keep torturing. Real solution:

• Have a very believable “main” hot wallet with $50k–$250k (enough to satisfy most crews).

• Real stack in geo-distributed multisig that literally cannot be moved without keys in 2–3 different countries and a 7–30 day timelock on large amounts.

• Practice your duress story: “That’s everything, I promise — the rest is in a multisig with my ex-wife in Canada and my lawyer in Switzerland. It takes weeks to move.”

• Safe room with ballistic blanket/door, satellite phone or VOIP line independent of home power, and a weapon if you’re trained.

Most tortured victims in 2025 were attacked together with spouses/kids/parents because the attackers knew the whole family would be home.

• Your spouse and adult children must be fully understand OpSec — no bragging, no crypto stickers, no “my husband is loaded in Bitcoin” comments at school events.

• Domestic staff (cleaners, nannies, gardeners) are the #1 leak vector. Vet them like you’re hiring a CIA asset — background checks, NDAs, never let them go if they ever ask about crypto.

• Give family pre-agreed code words for phone calls (AI voice cloning + fake kidnapping calls are now common).

Bitcoin 2025 in Vegas and every major conference now has professional spotters.

• Book flights/hotels under alias or corporate name.

• Never post that you’re going until you’re already home.

• Use cash or privacy.com virtual cards for everything on-site.

• Travel with a “burner” phone and laptop that have zero access to real keys.

• If you’re a known whale, hire close protection for the duration — it’s $2–4k/day and worth every penny.

• Relocate to a truly safe jurisdiction (UAE, Singapore, Switzerland, or certain gated compounds in Puerto Rico/Cayman).

• Full-time executive protection team + armored vehicle with driver.

• Collaborative custody with institutions that have armed response protocols (e.g., AnchorWatch + private security integration).

• Life > Bitcoin. If attacked, comply as needed but use multisig delays to your advantage (“I need my partner in another country”).

• Have emergency lockdown features enabled on wallets/apps.

• Report incidents to authorities and communities (e.g., contribute to Lopp’s list) to help others.

• Have inheritance/dead-man-switch planning so funds aren’t lost if the worst happens.

Bottom line for end of 2025: The game has permanently changed. The crews doing these hits are no longer random junkies — they’re transnational gangs who research targets for months, use fake delivery uniforms bought on Telegram, and are willing to waterboard you while your kids watch if they think you have more. Silence, geographic distribution of keys, and making yourself an annoyingly hard target are now non-negotiable if you want to keep both your bitcoin and your fingernails.

Maximum physical privacy as a crypto whale requires treating yourself like a high-net-worth individual in witness protection — constant vigilance, multiple defense layers, and acceptance that perfect security doesn’t exist, only making attacks too costly or difficult. The combination of strict OpSec, physical fortifications, geographically distributed multisig, and scam paranoia has kept many whales safe despite rising threats.

Implement these gradually, starting with the basics: shut up about your stack, secure your home, and your home, and distribute your keys. Your wealth is freedom — don’t let poor OpSec turn it into a liability. Stay safe!
