Better protection needed as violent cryptocurrency robberies surge

As cryptocurrency's value increases, it becomes an appealing target for violent criminals, according to industry experts. One approach that falls short is simply treating physical safety as secondary to financial security. To address this vulnerability, the crypto industry should design products and services that account for the threat of forceful coercion.

"Wrench attacks"—where physical violence or threats are used to force someone to surrender their cryptocurrency—are on the rise. This leaves digital wallets secure against hacking but vulnerable to psychological manipulation. Some holders can immediately authorize large sums, making them prime targets for criminal coercion. In the first half of the year, violent criminals extracted over $30 million from cryptocurrency holders, potentially exceeding $58 million annually if the trend continues.

The industry needs to expand its definition of investor protection beyond price volatility, account theft, and platform failures. Worldwide, 46 documented incidents of physical coercion were reported by late June. People can become targets despite having growing cryptocurrency wealth while their physical security arrangements remain unchanged.

For example, a cryptocurrency investor in Solihull, England, was attacked by masked intruders at his home, threatening his pregnant wife and forcing him to transfer hundreds of thousands of pounds worth of cryptocurrency during a 45-minute ordeal. Similarly, a man in Hong Kong was assaulted in a hotel and robbed of about $675,342 worth of cryptocurrency, plus additional silver worth $800,000.

These cases highlight an uncomfortable limitation of digital security: completing required security steps does not guarantee a free-willed decision. Self-custody of cryptocurrency places extensive financial authority in one person's hands, increasing the risk of coercion. Traditional finance also faces coercion, but it has mechanisms like withdrawal limits and independent approvals that can intervene.

These measures, while imposing costs on legitimate users, are essential protective values that deserve recognition when evaluating financial products. While avoiding publicizing wealth can be helpful, it cannot replace institutional responsibility for protecting investors. Criminals can be exposed through records or information they never intended to disclose.

However, the industry's response should address both custody design and surrounding services. Implementing multiple independent approvals can reduce reliance on a single key or device, and delayed withdrawals or transaction limits can lessen the amount accessible during periods of coercion. These mechanisms do not guarantee physical safety, but they introduce complexity and may deter criminals.

Blockchain records can aid criminal investigations, but traceability alone does not provide the power to freeze or recover assets. In some cases, like the rescue of kidnapped Ledger co-founder David Balland and his partner, French authorities traced, froze, and seized nearly all the cryptocurrency paid as ransom. This outcome depended on investigators, operational intervention, and institutional cooperation.

This example shows how practical protection of digital ownership continues to rely on public systems. Financial losses only capture part of the harm caused by extortion attempts. An unsuccessful attempt can still leave a person injured, a family displaced, or a child traumatized, even if the stolen funds are fully recovered. As cryptocurrency fortunes grow across market cycles, the industry must recognize that wealth changes its owners' exposure to crime.

Security promises should be tested under conditions where customers are frightened, isolated, or protecting a loved one. A rising valuation can make an investor wealthier, but a mature financial ecosystem must also provide credible ways to ensure their continued safety.
