In early 2025, OKB — the native token of crypto exchange OKX — surged past $6, marking a new all-time high with a 90.15% gain over the previous 30 days. This rally reignited public interest in a long-standing mystery: the unresolved dispute between OKX and Yang Yongxing, a once-celebrated hedge fund manager who vanished from the financial spotlight for nearly a decade — only to resurface deep within the cryptocurrency ecosystem.
From Stock Market Prodigy to Crypto Phantom
Yang Yongxing, often described as a "short-term trading genius," first made his name in China’s traditional finance world. Born in Zhengzhou to a working-class family, he was introduced to the stock market at a young age by his father, who handed him a modest 20,000 RMB account to manage. By 2006–2007, during China’s stock market boom, Yang achieved legendary status by winning back-to-back titles on the Chaoyang Yongxu Private Fund Leaderboard. At just 25, he reportedly delivered an eye-popping 1,497% return while working as an investment manager at Silicon Valley Fund.
In 2009, Yang transitioned into the formal private equity space, launching his first trust-based fund product, Strategy Master, which delivered a 193% net growth over one year. He soon founded Shenzhen Yongsheng Huiyuan Investment and launched his final fund, Yongsheng Huiyuan Steady Appreciation. However, by 2011, rumors swirled that Yang was under investigation for alleged market manipulation due to his extraordinary performance. While he denied any wrongdoing, he subsequently disappeared from public view — until 2019.

The Hidden Gateway: GBC Capital and the Singapore Connection
Though Yang has never officially confirmed his full crypto portfolio, investigative findings suggest he entered the blockchain space around late 2017, focusing on major platform tokens like OKB, HT (Huobi Token), BNB (Binance Coin), and Bitcoin (BTC). His direct public investments include a blockchain media outlet and a mining hardware firm. But the more significant — and discreet — link lies with Geek Blockchain Capital (GBC), a Singapore-based blockchain investment firm.
Registered in June 2018, GBC operates with the secrecy typical of traditional hedge funds. It rarely appears in public events or media coverage. One of the few traces of its existence comes from a 2018 blockchain conference in Shenzhen, where “Jason,” identified as GBC’s CEO, was listed in the press release.
LinkedIn profiles reveal that Wang Lingsheng has served as GBC’s founder and CEO since March 2018. Crucially, Wang is also a senior investment manager at Shenzhen Sunflower Investment Co., a company whose legal representative and actual controller is none other than Yang Yongxing. Further ties emerge through two other entities — Zhoushan Sunflower Chaoyang Equity Investment Partnership and Zhangzhou Port Sunflower Venture Capital — where Wang holds shares but Yang remains the ultimate beneficiary.
This network strongly implies that GBC functions as Yang’s proxy in the crypto world — a silent hand guiding strategic investments while maintaining operational separation.
Strategic Bets: When Investments Outpace Projects
Despite its low profile, GBC has made several notable moves in the blockchain space:
- Usechain (2018): A high-profile public blockchain project founded by Cao Huining, a finance professor at Cheung Kong Graduate School of Business. GBC invested during the project’s launch phase. However, by late 2019, Usechain reportedly disbanded its core team. Its token, USE, now trades around $0.0006 — down over 88% from its private sale price and never recovering after its market debut.
- DragonEx (Lóngwǎng): A digital asset exchange that issued its own utility token, DT. In August 2018, GBC became one of four global super nodes by staking 30,000 DT (then valued at ~$3.6 each). After DragonEx suffered a $6 million hack in April 2019, GBC injected $370,000 into a recovery fund and received 370,000 DT in return at a fixed rate of $1 per DT — significantly below the market price of ~$1.8 at the time.
Three months later, DT peaked at $5.4 before settling around $2 today. Even at current levels, GBC doubled its investment — a rare win in a space filled with failed exchanges and abandoned tokens.
Notably, DragonEx claimed GBC’s DT holdings would be permanently frozen and managed by a third party under public supervision. Yet the wallet address has never been disclosed. Official reports show only about 1.26 million DT held in the foundation’s name — far less than what GBC should possess.
Mining Ties and Public Reemergence
Yang has also confirmed involvement in the mining hardware sector, reportedly holding equity in Ebang International, a manufacturer of ASIC miners. Ebang filed for a Hong Kong IPO in mid-2024 but later had its application lapse. The company has also faced scrutiny over alleged ties to Yindouwang’s illegal fundraising case.
What makes Yang’s story even more intriguing is his sudden shift from reclusion to media visibility starting in 2024 — a complete reversal after ten years of silence.

The OKX Dispute That Broke the Silence
The catalyst for Yang’s return was an exposé published by One Hard Coin, a blockchain media outlet. On August 19, 2024, it reported that a user known as “Mr. Wang” lost access to his OKX account containing nearly $100 million in digital assets.
Further investigation revealed that One Hard Coin is operated by Shenzhen 3 o’Clock Information Technology Co., in which Shenzhen Yongsheng Huiyuan Investment — Yang’s firm — holds a 16.97% stake. By October 2024, “Mr. Wang” was unmasked as Yang Yongxing himself.
He claimed his OKX account was frozen and eventually deleted, along with those of over 20 associates who followed him into crypto — totaling approximately 800 million RMB ($110 million USD), including 2,800 OKB tokens. He presented what he called “a thick stack of evidence” to journalists, though no verifiable proof of account ownership has been made public.
Yang subsequently filed legal action against OKX and its founder Xu Mingxing.
Xu responded on social media, alleging that Yang had acquired a 1% stake in OKCoin through him and received a 100% return on investment — but then demanded additional profits and launched a smear campaign when refused. Jay Hao, CEO of OKX, countered that no account matching such transaction volume exists in their system.
To date, no court ruling has been issued. The truth remains obscured by conflicting narratives.
Frequently Asked Questions
Q: Who is Yang Yongxing?
A: A former hedge fund prodigy known for achieving over 1,497% returns in 2007. After disappearing from finance around 2011, he resurfaced in 2019 amid a high-profile dispute with crypto exchange OKX.
Q: Is there proof that Yang Yongxing invested through GBC Capital?
A: While no direct admission exists, structural links — including shared executives and beneficial ownership — strongly suggest GBC operates as an extension of Yang’s investment network.
Q: What happened to Usechain?
A: Once promoted as a privacy-focused public chain led by a well-known academic, Usechain collapsed by late 2019 with team dissolution and minimal node activity. Its token remains deeply devalued.
Q: Did GBC profit from DragonEx?
A: Yes. Through strategic positioning during a post-hack recovery initiative, GBC acquired DT tokens below market value and realized substantial gains as prices rose — even amid broader exchange decline.
Q: Why did Yang suddenly go public after years of silence?
A: His media appearances coincided with the exposure of his alleged asset loss on OKX. Legal conflict appears to have forced his hand after nearly a decade of operating off-grid.
Q: Has the OKX lawsuit been resolved?
A: As of early 2025, the case remains unresolved. Neither side has provided conclusive evidence accepted by courts or regulators.
