Sister Bai has been in the cryptocurrency space for 13 years, witnessing both the euphoric spikes and the despair of losing all capital. However, the Qian Zhiming case still sends chills down people's spines. This cross-border cryptocurrency fraud, involving 128,000 investors, has siphoned off approximately 195,000 Bitcoins, with only 61,000 seized by British police, leaving more than two-thirds unaccounted for. Behind the case are all the challenges of cross-border rights protection for virtual assets, each hitting the soft spot of cryptocurrency investors.

1. Scam Breakdown: The Ponzi Trap Wrapped in High Technology
From 2014 to 2017, at the height of the Bitcoin craze, Qian Zhiming controlled Tianjin Lantian Grey Company and orchestrated a precisely targeted scam. He launched products such as computing power financial management, Bitcoin mining machine investment, and encrypted digital asset appreciation plans, with names that were obscure and difficult to understand, but were essentially typical Ponzi schemes—paying returns to old investors using the money from new investors.
To create a 'reliable' facade, the company rented top-tier office buildings and impressive display centers in Beijing, Tianjin, and Shanghai, customized exquisite promotional materials, and invited social celebrities to endorse them. Through a combination of online promotion and offline multi-level marketing, they attracted 128,000 investors over three years, ranging from elderly individuals who knew nothing about blockchain to financial professionals, all lured in by the promise of high returns, pouring their savings into so-called 'high-tech projects.'
In the second half of 2017, the funding chain broke, leading to withdrawal difficulties, and the scam completely collapsed. Executives had long misappropriated funds to purchase luxury homes and cars, leaving investors with nothing but total losses.
II. International Pursuit: The Seizure of 61,000 Bitcoins and the Fog of Confusion
Before the scam exploded, Qian Zhimin fled to the UK using a fake passport, purchasing a luxury home in London under the alias 'Zhang Yadi' in an attempt to hide. However, his lavish lifestyle and unusual cash flows drew the attention of UK regulators. In 2018, during an investigation into another money laundering case, police identified him and seized a cryptocurrency hardware wallet containing 61,000 Bitcoins, valued at over £5 billion at current prices, setting the record for the largest cryptocurrency seizure in UK criminal investigation history.
The decentralized nature of Bitcoin makes it impossible for the police to directly obtain private keys; they can only work with blockchain analysis companies to freeze assets using technical means. More challenging is the asset gap: of the 195,000 Bitcoins involved, over 120,000 are missing. Qian Zhimin admitted to still controlling a wallet containing 20,000 Bitcoins but claimed to have forgotten the password—such excuses are common in cryptocurrency cases; once the private key is lost, the assets are permanently locked on the blockchain, serving both as a means of evasion and a fallback strategy.
Tracking is extremely difficult: Qian Zhimin is associated with over 200 Bitcoin addresses, with complex money flows, some entering exchanges for asset conversion, some mixed through mixing services disrupting traces, and some hidden in cold wallets that have remained untouched since 2018. Coupled with the anonymity and cross-border liquidity of Bitcoin, the police can only investigate within their own jurisdiction, making it nearly impossible to recover assets that flow into uncooperative tax havens.
III. Judicial Dilemma: Multiple Barriers to International Compensation
In September 2025, Qian Zhimin was charged with two counts of money laundering at Southwark Crown Court in London and was sentenced to 11 years and 8 months in prison after pleading guilty. However, the road to compensation is fraught with difficulties due to the differences between Chinese and British judicial systems. China supports criminal civil litigation, while the UK requires victims to initiate civil recovery proceedings separately or claim under the Proceeds of Crime Act 2002, making it difficult to bridge the two systems.
The UK prosecution proposed an 'asset reservation and transfer' scheme: the court determines the total amount of compensation, reserves the assets, and then transfers them to the Chinese government for distribution, bypassing the challenge of directly facing hundreds of thousands of victims in the UK courts. However, victim lawyers strongly opposed this, arguing that the assets should be returned directly to the victims rather than being passed through the government, with both sides holding firm to their positions.
The proliferation of agents complicates the situation: at least five UK law firms are involved, each representing different victim groups, with varying demands and strategies, leading to duplicated efforts and skyrocketing legal fees—such cases can easily incur legal fees of hundreds of thousands or even millions of pounds, which will ultimately be deducted from the assets involved; the longer it drags on, the less the victims will receive. Moreover, there is a significant disparity among different victims, with early and late investors experiencing different loss ratios and varying levels of evidence completeness, making it difficult to establish a unified agency committee like in the Madoff case.
The evidence threshold also poses obstacles: UK courts require victims to submit detailed transaction records, contracts, and other materials, which need to be translated into English and notarized, consuming time, effort, and money, making many victims hesitant to proceed.
IV. Practical Considerations: Price Volatility and Attempts to Break the Deadlock
The extreme volatility of Bitcoin adds further uncertainty to compensation. When the case occurred in 2017, it was worth less than £1,000, soaring to nearly £15,000 by the end of the year, subsequently dropping below £3,000 in 2018, and then rising again to tens of thousands of pounds in 2025 during the trial, with valuations at different points in time varying drastically. Based on the time of the incident, 61,000 Bitcoins were worth between £450 million and £900 million; at current prices, they exceed £5 billion, and the choice of valuation time directly determines how much victims can recover.
The court also faces disposal challenges: immediate sales might miss out on potential price increases, while delays could lead to depreciation, and professional custodians are needed to ensure asset security through multi-signature and cold storage, with custodial fees still deducted from the assets. Experts have proposed hedging solutions, using futures and options to lock in value or using smart contracts for automatic asset distribution, but both face questions of legal recognition and technical vulnerabilities, making practical implementation extremely difficult.
V. Subsequent Developments and Insights from the Cryptocurrency World
Currently, the case involves multiple parallel proceedings: Qian Zhimin's civil recovery, Blue Sky Grey's bankruptcy liquidation in the UK, and separate civil lawsuits from some investors, which are interlinked and can easily lead to resource wastage and contradictory judgments. The court has suggested that before the hearing on February 16, 2026, lawyers from all parties submit a coordination plan, possibly designating a law firm to lead, establishing a steering committee, or appointing a special moderator, with the core aim of reducing procedural complexity and costs.
This case also exposes the core conflict between cryptocurrency assets and traditional judicial systems: decentralization, anonymity, and cross-border liquidity are at odds with national regulatory frameworks. Although there are relevant international conventions, responses to cryptocurrency asset cases remain weak, and this case may provide an important reference for global judicial handling of cryptocurrency assets.
Sister Bai wants to remind everyone: there has never been a 'sure-win' high-tech project in the cryptocurrency world; lavish events, endorsements, and high-yield pitches are often the guise of scams. Once you fall into a pit, cross-border rights protection is as difficult as climbing to the sky, and preserving evidence and asset management (especially private keys) is the survival bottom line for every investor. The final outcome of this case remains uncertain, but the lessons it leaves behind are worth remembering for everyone in the cryptocurrency community.
