On March 21, 2025, on platform X, on-chain detective ZachXBT published an investigative report revealing the true identity of a Hyperliquid whale who earned approximately $20 million through high-leverage trading.

High-Leverage Trading Profits

ZachXBT reported that the trader made approximately $20 million through high-leverage trading on Hyperliquid and GMX over the past few weeks. The most notable trades were two transactions made from January to March 2025:

  • Wallet 0xe4d3 opened long positions in ETH and BTC with 50x leverage before Trump announced the cryptocurrency reserve plan, profiting $10 million.

  • Wallet 0xf3f4 opened short positions in BTC with 40x leverage, profiting $9 million.

These two trades drew attention due to their precise timing and high returns.

Suspicious Source of Funds

ZachXBT traced addresses interacting with 0xf3f (such as 0x7ab8, 0x312f, etc.) and found that some addresses were associated with platforms like Roobet, Binance, and Gamdom. Among them, 0x7ab8 was confirmed as the fee receiving address for the phishing site projection[.]fi, which received $17,100 from victims in January 2025.

The source of funds also points to withdrawal addresses from four casinos on Solana. ZachXBT stated: "One of the casinos confirmed that the funds came from exploiting a game input validation vulnerability." ZachXBT also discovered that the trader had negotiated with the casino using a Telegram account (ID: 7713976571), which has since been deleted.

Identity Revealed: The Criminal Trajectory of William Parker

Through open-source intelligence (OSINT) and payment records of 0xe4d3, ZachXBT identified a UK phone number linked to a person named William Parker. The report states: "Public records indicate that William Parker is likely the owner of this number." Interestingly, William Parker is not a first-time offender; he has previously used the alias Alistair Packover and has a long criminal history:

  • In 2023, he was arrested in Finland for stealing approximately $1 million from two casinos and served time.

  • In the early 2010s, he made headlines in the UK multiple times for hacking and gambling-related fraud.

ZachXBT concluded: "It is evident that William Parker has not learned his lesson after serving time for fraud over the years and continues to gamble." Currently, most of his funds remain in address 0x51d99A4022a55CAd07a3c958F0600d8bb0B39921.

Conclusion: The Illegal Path from Six Figures to $20 Million

ZachXBT provided a brief overview at the end of the report: "In January 2025, a person with multiple prior criminal charges obtained funds through casino vulnerabilities and phishing attacks, subsequently turning six-figure funds into $20 million through high-leverage trading." This incident not only reveals the high-risk, high-reward nature of the cryptocurrency market but also highlights the regulatory challenges of illegal funds flowing into on-chain transactions.

As for ZachXBT's investigation results, the X account associated with the whale has yet to respond.
