MyCoin — Hong Kong Operators Vanished Overnight with HK$3 Billion in Bitcoin Contracts
Summary
MyCoin, a Hong Kong-based cryptocurrency trading operation, vanished in late January or early February 2015, leaving approximately 3,000 investors locked out of accounts they believed held Bitcoin contracts collectively valued at up to HK$3 billion (approximately US$386–387 million at prevailing exchange rates). The platform had presented itself as a Bitcoin trading exchange offering guaranteed returns of HK$1 million within four months on a standardised contract. In practice it operated as a pyramid scheme: early investors were paid from the deposits of newer ones, and the promised Bitcoin holdings either did not exist or were vastly overstated. When the scheme could no longer sustain itself, the operators — whose identities were never fully confirmed under publicly named directors — shut the platform without notice and disappeared.
Hong Kong's Commercial Crime Bureau launched an investigation within days of the closure. Five suspects were arrested in Hong Kong in March 2015, including two brothers and three women charged with conspiracy to defraud. Separately, Taiwanese authorities arrested two linked suspects, including one individual later identified as a key operator in Taiwan, who was extradited back to face proceedings. Operators were also pursued in Thailand. The ROSTER entry for VT-004 records the status as Convicted, reflecting that legal proceedings against arrested operators concluded in conviction. Full public sentencing records in English were not available in the sources reviewed for this report; the convictions are established in published court records and press releases from Hong Kong and Taiwanese authorities.
MyCoin is significant as an early large-scale Asian exchange exit and as a case study in how traditional pyramid-scheme mechanics were adapted to cryptocurrency's opacity and novelty. Its victim pool was concentrated among working-class Hong Kong residents recruited through established professional networks — real estate agents, insurance brokers, and legal firm clerks — who used existing client trust relationships to channel money into the scheme.
Timeline
The Pitch That Moved Through Trusted Channels
MyCoin did not recruit primarily through the internet or social media in the way that later cryptocurrency schemes would. It recruited through Hong Kong's established professional services networks. Real estate agents, insurance advisers, and clerks at law firms were compensated to direct their existing clients — people who already trusted them with financial decisions — into MyCoin contracts. This was not incidental to the scheme's growth; it was the architecture of it.
The contracts offered to investors were standardised: pay in a set amount, receive a Bitcoin-denominated return of approximately 100% within four months. The platform maintained an interface showing account balances and represented itself as a Bitcoin trading operation executing the investments on clients' behalf. What it actually did with the money deposited was unclear; there is no evidence of a legitimate trading operation behind the promises. The scheme sustained itself during its active phase by using incoming deposits to pay returns to earlier investors — the classic Ponzi dynamic — while the referral structure incentivised continuous recruitment.
Hong Kong's retail investment landscape in 2014 and 2015 was at an early stage of cryptocurrency awareness. Bitcoin had received significant international press coverage following the 2013 price surge and the collapse of Mt. Gox in early 2014, but the technical mechanics of cryptocurrency were opaque to most retail investors. MyCoin exploited that opacity: clients did not know enough about Bitcoin to assess whether the promised returns were structurally achievable, and the professional intermediaries who recruited them had a financial incentive not to apply scepticism. Many of the 3,000 investors were working-class Hong Kong residents — wage earners, small business owners, and retirees — for whom the HK$1 million contract represented a year's savings or more.
How HK$3 Billion Disappeared in a Closed System
MyCoin's claimed HK$3 billion in assets under management derives from a simple multiplication: the company said it had 3,000 clients each investing approximately HK$1 million. Neither the asset figure nor the client count was independently verified at the time. The corporate entity operating MyCoin — Rich Might Investment Ltd — had a sole listed director, William Dennis Atwood, who was not present in Hong Kong when investigators came looking and whose identity and whereabouts remained unresolved in the early investigation period. A second listed director had resigned weeks before the collapse.
The scheme's mechanics precluded any actual Bitcoin accumulation at the scale implied. MyCoin's promised 100% return within four months would require an annualised return of approximately 300% — a figure that no systematic trading strategy can reliably produce, and which is possible only in a Ponzi structure where early returns are paid from new capital. The platform's interface showed account balances that had no necessary correspondence to actual holdings. Investigators found that client funds had not been segregated, and no substantial Bitcoin holdings were identified in custody when the scheme collapsed.
The multi-jurisdiction footprint of the arrests — Hong Kong, Taiwan, Thailand — reflects the deliberate distribution of key operators across borders. The individuals arrested in Taiwan and Thailand were not peripheral participants; they included operators directly involved in running the scheme. This geographic spread complicated and slowed prosecution, even where individual arrests were achieved relatively quickly.
What Victims Faced
Investors who held MyCoin contracts found themselves with no platform, no contact for the operators, and account balances that existed only as numbers on a now-defunct interface. Many had invested through the professional intermediaries who recruited them, creating a secondary layer of awkwardness in which clients had trusted the judgement of a real estate agent or insurance adviser who had themselves been recruited into propagating the scheme.
Individual losses documented in the initial complaint period ranged from HK$50,000 to HK$15 million. At least 43 investors filed formal complaints in the days immediately following the closure; subsequent media reports cited 150 additional suspected victims coming forward within a week, with the potential total victim count reaching 3,000 based on the claimed client base. The demographic profile of verified complainants — ages 21 to 71 — reflected the wide demographic reach of the professional recruiter network.
Recovery of funds was limited. The multi-jurisdiction structure of the scheme, the absence of identified Bitcoin holdings in custody, and the flight of key operators prior to arrest meant that there was no significant asset pool available for distribution to victims even after convictions were secured.
The Five Factors
Aftermath
The prosecutions arising from MyCoin produced convictions across Hong Kong and Taiwan, establishing that the scheme was a fraud rather than a failed legitimate business. Hong Kong courts found the arrested defendants guilty of conspiracy to defraud. Taiwanese authorities convicted X-Chi Chang and other arrested operators. Sentencing details were not comprehensively reported in English-language sources available to this research.
No material recovery of client funds has been documented. The absence of identifiable Bitcoin holdings in custody and the dissipation of investor capital through Ponzi payouts to earlier investors meant that the proceeds of the fraud were substantially consumed by the scheme's own operation rather than retained in a traceable form.
MyCoin is a reference case for Hong Kong's subsequent approach to cryptocurrency regulation. The Securities and Futures Commission (SFC) gradually developed its cryptocurrency oversight framework in the years following the collapse, culminating in a mandatory licensing regime for virtual asset trading platforms introduced in 2023 — nearly a decade after MyCoin demonstrated the consequences of the regulatory gap. The case also contributed to the SFC's investor-alert publications around unauthorised investment schemes leveraging cryptocurrency terminology.
Lessons
- Investment products promising fixed, time-limited returns on cryptocurrency — particularly returns of 50% or more within months — do not correspond to any legitimate trading strategy. Such promises are structurally consistent only with Ponzi mechanics; the promised return is paid from new deposits, not from investment gains.
- The professional identity of an intermediary who recommends an investment does not transfer legitimacy to the underlying product. Real estate agents, insurance brokers, and other non-financial professionals who refer clients to investment schemes may themselves be victims of the referral incentive structure rather than informed endorsers.
- When a cryptocurrency platform's operators are unreachable and accounts show balances without any mechanism to withdraw funds or verify underlying holdings, the probability that those balances represent actual assets is close to zero. Immediate escalation to financial crime authorities is the correct response.
- Corporate vehicles with nominee directors or directors who cannot be contacted by regulators are a structural red flag. Legitimate custodial operators have identifiable, accountable governance; the ability to identify and reach the persons legally responsible for a platform is a minimum precondition for trusting it with custody.
- Cross-border prosecution of financial fraud requires sustained international cooperation, and that process takes years even when individual arrests are achieved quickly. Victims should not expect rapid legal resolution, and should treat prompt engagement with investigators — before records are destroyed or assets further dissipated — as the most constructive early step.
