Personal Security for High Networth Individuals in Crypto

Personal security for high networth individuals now has to account for a simple fact that no wallet manufacturer can engineer away: a person can be made to open anything if someone is holding a knife to them in their own kitchen.

I have spent years protecting families whose wealth is visible in some way. Real estate, a company, a public role, a famous name. Digital assets add a new twist. The wealth is invisible on paper, yet it can be moved in minutes by one person with one device, and that person is the target.

Two stories from this week put that in front of me again. One is a claim out of the United Kingdom that has not been confirmed by police. The other came out of a Toronto courtroom, where a man who was kidnapped in 2022 stood up and described what the years since have been like. Neither story is about clever hacking. Both are about people.

If you want the wider framework that sits behind this article, I lay it out in High Net Worth Security: The 2026 Guide for UHNW Families.

Personal security for high networth individuals holding digital assets

Most of the security advice crypto holders receive is technical. Use a hardware wallet. Write the seed phrase down and keep it offline. Turn on every form of authentication you can find. Do not click links. All of that is reasonable, and none of it addresses the person standing in the hallway at two in the morning.

Personal security for high networth individuals who hold digital assets is a physical problem first. The keys may live on a device, but the device lives in a house, and the house has a front door, a garage, a side gate, a dog that may or may not bark, and a family asleep upstairs. Criminals who want the money do not need to break encryption. They need to get close to the person who can sign the transaction.

That is the shift I want families and family offices to understand. A strong technical setup moves the attack, it does not end it. When the safe is too hard to crack, criminals go after whoever knows the combination. When the wallet is too hard to steal, they go after whoever can unlock it.

So the questions I ask are the same ones I ask about any other high-value principal:

• Who knows this person holds significant assets?
• Who knows where they sleep?
• How predictable is their day?
• What happens at the house between midnight and six?
• Who would notice if someone was watching?

Those are questions about high net worth security, not about cryptography. And they are the questions most crypto holders have never been asked.

Why this is not a niche problem anymore

I used to hear “wrench attack” mentioned as a joke in crypto circles. The phrase comes from the idea that it is cheaper to hit someone with a wrench than to crack their encryption. It stopped being funny a while ago.

CoinDesk reported on October 13 that blockchain analytics firm Chainalysis estimates criminals stole more than $30 million through violent attacks in the first half of 2026, and that home invasions accounted for 37% of recorded incidents, up from 14% a year earlier. The same report cites blockchain security firm CertiK identifying 52 verified attacks worldwide in that period.

The number that matters most to me in that paragraph is the home invasion share. More of these attacks are happening at the residence. That makes home security for high net worth individuals with crypto exposure a direct part of protecting the assets, not a separate topic.

Key takeaways

• Hardware wallets and self custody protect against remote theft. They do not protect the person who can unlock them. A physical threat bypasses every technical control.
• CoinDesk, citing Chainalysis, reported that home invasions made up 37% of recorded violent crypto attacks in the first half of 2026, up from 14% a year earlier. The residence is now the main stage.
• What people post about their holdings, cars, travel and homes can turn into a target list. Reducing that exposure is protective work.
• Home security for high net worth individuals with digital assets needs detection at the perimeter and a plan for what happens if intruders get inside.
• The aftermath of a kidnapping can last years. Planning for recovery, family safety and changed routines belongs in the program from the start.

The UK knifepoint transfer claim

According to CoinDesk, a crypto trader in the United Kingdom who posts under a pseudonym on X said masked intruders broke into his home, held him at knifepoint, destroyed his phone and forced him to transfer about $760,000 in digital assets. He said roughly $40,000 came from a hot wallet and $720,000 from his Ledger hardware wallet. He shared a wallet address on a blockchain explorer to back up his account.

CoinDesk was careful to note that police and other authorities had not confirmed the incident. I want to be just as careful. This is one person’s account. I am not treating it as an established case.

But the shape of what he described matters for planning, whether or not every detail holds up, because it lines up with the pattern the analytics firms are seeing:

• The attackers came to the home.
• They controlled the person.
• They took away the phone.
• They forced the transfer on the spot.

Notice what was useless in that sequence. The hardware wallet did exactly what it was designed to do. It kept the private keys off the internet. It did nothing once a knife entered the room, because the owner could still unlock it, and the attackers knew that.

What the destroyed phone tells me

One detail jumps out at me every time I read accounts like this: the phone. In the Puçol home invasion I wrote about this week, reporting said the intruders took the family’s mobile phones first. In this UK claim, the trader said the phone was destroyed.

Phones are how people call for help. They are also, for a lot of crypto holders, how they receive alerts from the camera system, open the gate and talk to whoever is responsible for security. Take the phone and you take all of that at once.

A protective program that depends on the principal holding a working phone during an emergency has a single point of failure. I want alerts going to someone who is not in the room. I want a way to signal distress that does not require unlocking a screen. And I want somebody whose job it is to notice when the principal goes quiet.

Why the amount is less important than the method

It is tempting to focus on the dollar figure. I would rather focus on how long it took. A transfer of that size can be pushed through while the victim is still being held. Unlike a bank wire, there may be no fraud desk calling back, no hold period and, in many cases, no way to reverse it.

That speed changes how I think about response. With a traditional burglary, the goal is often to delay intruders long enough for help to arrive before they finish. With a coerced crypto transfer, the damage can be done in the first few minutes after they reach the person. So the work has to happen earlier: at the street, at the perimeter, at the door. By the time intruders are standing over someone with a device in his hand, most of the useful protection has already failed.

What the Toronto sentencing hearing showed

On October 15, CBC News reported on a sentencing submissions hearing in Ontario Superior Court in Toronto for Deren Akyeam-Pong, who pleaded guilty to nine charges related to the December 2022 kidnapping of Aiden Pleterski, a man who has called himself the “Crypto King.” Decrypt reported on the guilty plea in October 2025 and noted that the charges included kidnapping, assault and firearms offenses.

According to CBC, Pleterski thought he was meeting a potential investor on December 5, 2022, when a gun was pressed into his ribs in the back seat of a pickup truck. CBC reported that the agreed statement of facts from the guilty plea describes a three-day kidnapping during which he was threatened and tortured while being driven between several locations in southern Ontario. Three other men have also been charged in the kidnapping, and CBC reported that their trial is expected later this year.

I need to be precise about one more thing. Pleterski is himself on trial for fraud and money laundering, and CBC reported that he has pleaded not guilty. Those are allegations, and they are being tested in court. I have no view on them in this article. What I am interested in is the security lesson, and on that point Pleterski said something in his statement that I agree with completely. According to CBC, he told the court that “no financial dispute justifies kidnapping, violence or intimidation.”

The meeting was the trap

The detail that matters most to me is how it started. He believed he was going to a meeting with a potential investor. That is a familiar move. Someone offers a reason to meet, picks the time and place, and the target walks in without protection because it feels like business.

For anyone known to hold digital assets, I would treat unsolicited meetings with new contacts as a security event, not just a business decision. Who arranged it? Can the person be verified independently? Who picked the location? Does anyone on the protection side know where the principal will be and when to expect contact? Is the principal getting into someone else’s vehicle?

That last question is a hard rule for me. A principal who gets into a vehicle controlled by someone else has handed over control of the movement. I wrote about meetings and handovers in High-Value Transaction Security After Liverpool Kidnap, and the same principles apply here.

What the court heard about the years since

The part of the CBC story that stayed with me was not the description of the kidnapping. It was what came after. According to CBC, Pleterski told the court he has had to give up normal routines, including a steady job, as a safety precaution. He said he cannot sleep at night. He said he hopes that one day he will not have to look over his shoulder or worry about the safety of his family.

I hear versions of that from people who have been through violent crime. The event ends. The fear does not. Families change how they live. They move. They stop going places. Children notice. That is a real cost, and it is one most people never plan for.

Why self custody cannot stop coercion

Self custody means you hold your own keys. Nobody at an exchange can freeze your account or lose your funds. For many people, that is the whole point of owning crypto. It also means there is nobody else who can say no.

When a bank customer is forced to send a wire, there may be friction. A banker may call back. A large transfer may trigger a review. Some institutions require a second approval. That friction is annoying on a normal day and protective on a bad one.

A self-custody wallet has none of that by default. If you can sign, you can send. That is exactly why criminals go after people who hold their own keys.

I am not a financial adviser, and I will not tell anyone how to structure their holdings. But as a protection professional, I can say this: any arrangement where one person, alone, at home, can move a life-changing amount of money in a few minutes creates a physical security risk for that person and for everyone who lives with them. CoinDesk’s own summary pointed in the same direction, noting that protection extends beyond private keys to keeping holdings confidential, limiting public disclosure about trading activity and separating readily available funds from long-term reserves, while adding that no technical safeguard can eliminate the threat of violence.

The duress problem

People sometimes ask me about “duress wallets” or decoy accounts, where a person hands over a small wallet under threat and keeps the main holdings hidden. I understand the appeal. I am also cautious about it.

Here is my concern. A plan that depends on deceiving armed intruders while they are threatening your family is a plan that can go badly wrong. If they believe they are being lied to, the situation can escalate. I do not want any client betting their life or a child’s life on a bluff.

My priority in a confrontation is the same as in any home invasion: compliance to preserve life, then recovery. Everything else, the structure of holdings, the separation of keys, the delays, belongs before the confrontation, designed with qualified advisers, so that there is less for an attacker to take and less reason for anyone to come in the first place.

Social media as a target list

The cybersecurity consultant quoted by Decrypt said oversharing “practically paints a target on people’s backs” and described profit screenshots and photos of new cars as “open-source intelligence for criminals.” I agree with the substance of that.

When I build a threat picture for a new client, one of the first things I do is look at what the public can see. Not what the client thinks is public. What actually is. Very often the gap is wide.

The pieces that worry me most are rarely dramatic on their own:

A screenshot of a portfolio.

A photo in front of the house where the street number or a distinctive gate is visible.

A post about a trip, published while the family is still away.

A child’s school uniform in a picture.

A car with a readable plate.

A podcast appearance where the person talks about holding their own keys.

Any one of those might be harmless. Put together, they tell a stranger who you are, what you hold, where you live and when you are not paying attention. I go deeper into how online detail becomes physical exposure in UHNW Protective Intelligence From Online to Physical.

What I would do first

If someone came to me tomorrow with significant digital holdings and a public profile, I would start with exposure reduction, because it is cheap compared to everything that follows.

I would review what is posted about the person and family. I would look at what the property records and business filings reveal about the home. I would check whether the person’s crypto identity can be connected to their real name. And I would talk to the family about what gets posted from now on, especially during travel.

None of that requires the person to disappear. It requires deliberate choices. Post after you leave, not while you are there. Keep the house out of the background. Do not talk about how you hold your assets. Treat your holdings the way people with old money treat theirs, as something nobody else needs to know about.

Home security for high net worth individuals with crypto

Because so many of these attacks now happen at the residence, home security for high net worth individuals who hold digital assets deserves the same rigor I would give to a family with a visible art collection or a high public profile. In some ways more, because there is nothing to fence. The value can be carried out on a phone screen.

I approach the home in layers. The neighborhood. The property line. The grounds. The building shell. The occupied rooms. Each layer should either detect, delay or control access, and ideally more than one of those.

Detection before the door

In the cases I have read about this year, the moment that mattered was when intruders reached the people inside. I want to know they are coming long before that. That means exterior detection along the approaches that matter, cameras that someone actually watches or that alert someone awake, and lighting that removes the easy dark spots near the house.

I also want to know that the alarm is on. That sounds obvious. It is not. The Puçol case this week was reported to involve an alarm that had been left off. In my experience, alarms get disarmed because they are inconvenient. Pets set them off. Teenagers come home late. Someone forgets the code. If the system is a hassle, people stop using it. So the design has to fit how the family really lives.

Secondary entrances

Garages, service doors, pool houses and ground-floor windows tend to get less attention than the front door. That is where I look first on a walkthrough. A beautiful gate means little if the side yard has a low wall and a dark path to an unlocked utility room.

A plan for the occupied house

Every family I work with should know what to do if someone gets inside while they are home. Where do they go? Who takes the children? How do they call for help if the phones are gone? Who on the outside notices that something is wrong?

For some homes, that includes a protected room. I cover design and placement in Safe Room Planning for UHNW Homes. For others, it means overnight residential security officers who are awake, on the property and responsible for responding. The right answer depends on the house and the family. What is never acceptable is no answer at all.

This is also where our in-house research and development at MSB Protection comes in. Unlike most security providers, we run our own R&D effort aimed at countering threats like these. For me that means continually testing how intruders actually get into homes and where conventional setups fall short, so the measures we recommend are built around how attacks happen rather than around what a catalog happens to sell.

Separation of keys and people

There is a principle in protection work I come back to often: do not let the most valuable thing in the house depend entirely on one person who can be reached.

For crypto holders, that means thinking hard, with qualified financial and legal advisers, about whether the person at home should be able to move everything alone. I will leave the technical options to the specialists. My contribution is the physical side.

If keys or backup materials are stored in the home, who knows where? If a family member can be used as leverage, does the structure make that pointless? If a principal is forced to open something, how much can actually leave? Is there anyone outside the house who would notice an unusual transfer and raise the alarm?

I want to be clear about the limits here. No arrangement makes violence impossible. The goal is to reduce the payoff, increase the chances of detection and remove the idea that one visit to one house at night will produce a quick fortune.

The family is part of the attack surface

Criminals who cannot get to the principal sometimes go after a spouse, a child or a parent. That is why private security for high net worth family members, not just the person with the keys, belongs in the conversation. If an adult child lives in a separate apartment and is publicly linked to the family, that apartment is part of the risk picture. If an elderly parent lives alone, the same.

Close protection for UHNW families of holders

Most crypto holders I have met would never think of hiring close protection. It feels excessive. It feels like something for celebrities and heads of state. And for many of them, full-time protection is not necessary.

But close protection for UHNW families is not one thing. It is a scale. At one end, it is a periodic assessment and some training. Further along, it is a security driver for certain movements. Further still, it is a trained protection officer with the principal during higher-risk activities, like meetings with new contacts, travel to conferences or public appearances. At the far end, it is a full team.

The Toronto case is a good example of where a little help could have made a large difference. A meeting with someone new, at a place chosen by the other side, getting into their vehicle. Those are exactly the movements where I would want advance work, a driver who controls the vehicle and someone who knows where the principal is and when he should check in.

I describe how we structure this kind of work in our executive protection services. The core idea is simple: the riskiest moments are predictable, so protect those moments.

Events and conferences

Crypto conferences put a lot of people with digital wealth in one place, and their attendance is often announced in advance. Hotels near the venue are predictable. Badge photos and panel listings are public. If you are going, think about where you stay, how you move between the hotel and the venue, and who knows your room number. Keep the conference persona separate from your home address.

The aftermath nobody plans for

I want to return to what Pleterski told the court, because it is the part people skip.

Security plans usually end at the moment the threat is over. The intruders leave. The police arrive. The report is filed. In real life, that is the beginning of a long period that families are almost never ready for.

People stop sleeping. They jump at noises. They lose trust in places that used to feel safe. Some move house. Some cannot work normally. Children carry it with them into school. Spouses disagree about what to do next. And all of it happens while the family is trying to deal with police, insurers, lawyers and, sometimes, the press.

When I build a program, I want the plan to cover that period too:

• Who handles communication with law enforcement?
• Where does the family stay if the home no longer feels safe?
• Who changes access codes and locks?
• How do we assess whether the threat is really over?
• What support does the family need to recover?

I am not a counselor, and I do not pretend to be. But I can make sure the physical side is handled so the family is not also worrying about whether the people who came once will come again.

What recommended hnw security teams do differently

People sometimes search for recommended hnw security teams and expect a list of names. I cannot give you that list, and I would be wary of anyone who claims to be everyone’s first choice. What I can give you is a way to judge a team.

A good team will start with an assessment, not a sales pitch. It will ask about your public exposure, your routines and your home before it proposes anyone standing at a gate. It will be honest about what it cannot do. It will want to understand the family, not just the principal. And it will be able to describe, step by step, what happens when an alarm goes off at 3 a.m.

High net worth security services for crypto holders should also understand the specific pattern of these attacks: the home, the phone, the forced transfer, the speed. If a provider cannot talk about that clearly, they are protecting you from a different threat.

Where the family office fits

For families with a family office, the office often sees the assets but not the person. That gap is dangerous. Family office high net worth individuals security works best when the people managing money and the people managing protection talk to each other. If the office knows a principal is about to make a large transfer, travel or appear publicly, the protection side should know too. Security for UHNW family offices is not only about protecting the office. It is about connecting what the office knows to the people keeping the family safe.

Frequently asked questions

What does personal security for high networth individuals with crypto involve?

Personal security for high networth individuals who hold digital assets starts with reducing what strangers can learn about them, then protecting the home and the predictable movements where an attacker could get close. That usually means an exposure review, home security improvements, family planning for an intrusion and, for higher-risk activities, close protection or a security driver. Technical wallet security is important, but it does not stop physical coercion.

Do hardware wallets protect against wrench attacks?

No. A hardware wallet keeps keys away from remote attackers. If someone can force the owner to unlock it, it offers little protection. That is why physical security and confidentiality matter so much for holders.

How should home security for high net worth individuals change if they hold crypto?

Home security for high net worth individuals with digital assets should focus on early detection at the perimeter, consistent alarm use, attention to garages and secondary entrances, alerts that reach someone outside the room, and a clear plan for the family if intruders get inside.

When is close protection for UHNW families worth considering for crypto holders?

Close protection for UHNW families makes sense around higher-risk moments: meetings with new contacts, travel to industry events, public appearances, or after a specific threat. Many families start with an assessment and add protection for those moments rather than full-time coverage.

How do I judge recommended hnw security teams?

Ask how they assess risk, what they do overnight, who responds to an alarm, how they handle a principal who cannot use a phone and what they will not promise. Good high net worth security services explain their limits as clearly as their strengths.

Should a family office be involved in personal security?

Yes. Security for UHNW family offices works best when the office shares relevant information about transfers, travel and public activity with the people responsible for physical protection, so the plan matches what is really happening.

Conclusion: Protect the person who holds the keys

The technology around digital assets keeps improving. The weakness these attacks exploit has not changed at all. It is the person. A knife in a kitchen beats a perfect wallet every time, and the reported rise in home invasions shows that criminals have worked that out.

So the work has to move back to basics. Keep holdings private. Protect the home with real detection and a plan. Be careful about meetings and vehicles you do not control. Protect the family members who could be used as leverage. And plan for the long aftermath, because the court heard this week how long it can last.

That is the kind of high net worth security I want every holder to have. At MSB Protection, our in-house research and development work is aimed at exactly this kind of physical threat, and our residential and executive protection teams carry that thinking into every home and every movement we cover.
