A wallet security incident involving approximately $130 million in Bitcoin losses is reigniting discussions in the crypto industry about asset custody models: should Bitcoin holders rely on personal self-custody or turn to institutional custody? Hardware wallet manufacturer Coldcard had a vulnerability in its firmware in 2021 that led to some mnemonic phrases generated by the device being predictably risky. This vulnerability was discovered years later, and approximately 5,200 addresses and about 2,000 BTC have been stolen, with losses amounting to around $130 million.After the incident, some investors began to turn to Wall Street custody products. Data shows that the U.S. spot Bitcoin ETF saw a net inflow of about $626 million within days of the incident. Bloomberg ETF analyst Eric Balchunas stated that such security incidents could further drive funds into ETFs. However, the Bitcoin core community still insists on the self-custody concept. Casa co-founder Jameson Lopp stated that recent events should not undermine users' confidence in self-custody and pointed out that third-party custody also carries risks. Bitcoin Core early developer Peter Todd also believes that self-custody has a better long-term safety record than centralized institutions.Onramp co-founder Michael Tanguma believes that both options have flaws. He stated that concentrating a large amount of assets in a single institution creates a "honey pot," while hardware wallets face risks related to supply chains, firmware, and random number generation. Tanguma proposed a "multi-institution custody" solution, where multiple regulated institutions hold keys through a multi-signature mechanism, requiring multiple institutions to jointly sign any transaction to reduce single points of failure. However, this model has also sparked controversy. Critics argue that while multi-institution custody enhances security, it also introduces permissioned management, conflicting with the decentralized ideals originally pursued by Bitcoin. As Bitcoin gradually enters the fields of pensions, trusts, and institutional asset allocation, the industry is seeking new custody solutions suitable for long-term wealth management. The Coldcard vulnerability incident once again highlights that achieving a balance between security, decentralization, and usability remains a core challenge facing the Bitcoin ecosystem.

According to on-chain detective Specter, it has discovered a cluster of wallets holding 28,600 BTC, worth approximately $1.8 billion, suspected to be related to wallets previously attributed to the money laundering case of Zhimin Qian.A few weeks ago, a Bitcoin wallet that had been dormant since 2017 transferred 1,020 BTC, worth about $60 million, and began distributing funds to multiple addresses in a manner consistent with money laundering activities. After tracking these transactions, Specter found that the related wallet cluster was connected to publicly associated addresses investigated in the UK concerning Zhimin Qian. From 2014 to 2017, Zhimin Qian organized large-scale investment fraud in China, affecting over 128,000 victims. UK authorities later traced a significant amount of criminal proceeds flowing into Bitcoin, with the Met Police ultimately seizing 60,000 BTC, marking the largest cryptocurrency seizure in UK history at that time.In July 2021, UK authorities transferred the seized BTC, creating identifiable on-chain associations. Following the recent transfer of 1,020 BTC, Specter identified additional wallets, which currently hold a total of 28,600 BTC, worth approximately $1.8 billion. These wallets have largely been dormant since June 2021. Based on on-chain evidence, it remains unclear whether these wallets are still controlled by the same actor, other custodians, or have been identified by law enforcement.

According to the Daily Mail, the Inner London Crown Court recently ruled on a kidnapping and extortion case involving cryptocurrency tycoons. Two wealthy cryptocurrency tycoons from France (both in their 20s) were ambushed by a gang during their visit to London, held for over 52 hours, and subjected to torture including scalding water, cigarette burns, and being bound and beaten, while being forced to transfer $30,000 in cryptocurrency.The prosecution pointed out that the victims flaunted their wealth on social media, which may have attracted the attention of criminals. Ultimately, Gerson Borges and Mohamed Osman were found guilty of conspiracy to commit extortion and unlawful imprisonment, while Julius George, Isaac Bakoya, and William Adebisi were found guilty of unlawful imprisonment. The Flying Squad of the Metropolitan Police successfully rescued the hostages through mobile phone tracking and CCTV, and arrested some of the suspects after a high-speed chase. The mastermind "Nino" (Ibrahim Mohamed) is still at large.

According to statistics from Hong Kong law enforcement, from July 24 to 30, a total of 25 cases of investment fraud involving online romance were reported, with total losses nearing 70 million Hong Kong dollars. In one large online romance investment fraud case, a 50-year-old insurance practitioner was deceived by an online romantic partner claiming to be a "car dealer" into investing in virtual currency. Until last month, the victim discovered that the investment platform showed account earnings exceeding 800%, but when attempting to withdraw funds, the request was denied. Subsequently, both the online romantic partner and the so-called investment expert went offline, and the victim ultimately confirmed a cumulative loss of over 26 million Hong Kong dollars.The police remind investors to be vigilant about the behavior of recommending investment projects after establishing relationships through social platforms, especially those involving virtual currency, guaranteeing high returns, or requiring transactions through unfamiliar platforms. Do not relax financial safety precautions due to emotions or trust.

Since the implementation of the "Virtual Asset User Protection Act" two years ago, approximately 40 investigations into unfair virtual asset trading have been completed, and more than 30 cases have been reported or notified to judicial authorities, focusing on cracking down on market disorder behaviors such as short-term manipulation and "pump and dump."In the future, the ability to monitor the market will be further strengthened, and an AI-based virtual asset regulatory system will be established, including real-time market monitoring, second-level price manipulation analysis, and automatic identification of suspicious accounts and trading intervals.

A fraud review commissioned by the UK government suggests that the Judicial College should provide training for all judges and magistrates in England and Wales to address the increasing cases involving AI fraud and the use of cryptocurrency for money laundering. The report states that the overall Fraud Act 2006 can be used to handle AI fraud, but the issue lies in the courts' lack of preparedness to hear related cases.The report recommends evaluating whether the existing "long and complex trials" course should be updated or replaced with specialized modules on fraud and related crimes, and considers mandatory training for judges who may hear complex fraud cases. The report claims that fraud could soon account for half of all crime in England and Wales, with an estimated 4.1 million cases occurring within a year by June 2025, affecting 1 in every 14 adults and 1 in every 4 businesses. The Financial Ombudsman Service estimates that currently over half of investment scams involve crypto assets.The report also mentions the case of Qian Zhimin, who operated a Ponzi scheme in China, defrauding over 128,000 victims of approximately £5 billion and laundering the proceeds into Bitcoin. This case resulted in the largest confirmed Bitcoin seizure in UK history, exceeding 61,000 BTC, and Qian Zhimin was sentenced to 11 years and 8 months in prison at Southwark Crown Court in November.

According to Caixin, the case involving Qian Zhimin and 60,000 bitcoins held a three-day hearing from July 7 to 9, 2026. In the next phase, the focus of the case will gradually shift to evidence and tracing of assets, with substantive hearings expected to begin gradually after October this year.The court will focus on: 1. How the RMB investment funds entered Lantian Ge Rui and related accounts; 2. How the funds were gathered, transferred, and exchanged; 3. Which funds have a provable connection to the bitcoins seized in the UK; 4. The losses, repayments, and existing compensation situations of each applicant; 5. What specific property relationship exists between individual investors, Lantian Ge Rui, and the bitcoins involved in the case. Analysts believe that after the legal dispute was applied in July this year and the judge made a ruling, the case will gradually shift from "what law to judge by" to "whether the evidence can prove the rights."
