In the ever-evolving landscape of cryptocurrency trading, revelations can disrupt the status quo, particularly when a notorious figure emerges. Recently, crypto investigator ZachXBT has brought to light allegations that suggest the mysterious “Hyperliquid whale,” a trader who has reportedly profited around $20 million from leveraged trading, may be none other than a convicted criminal from the UK. As the crypto community buzzes with speculation, questions arise regarding the true identity of this enigmatic trader.
Mysterious Hyperliquid Whale Not A Crypto Insider
ZachXBT’s investigation, shared on social media, identifies the elusive trader as William Parker, who previously operated under the alias Alistair Packover. After changing his name, Parker found himself arrested and sentenced in Finland in 2024. His crimes include stealing nearly $1 million from online casinos back in 2023.
Since January 2025, Parker has made headlines with his trading activities on platforms such as Hyperliquid and GMX. However, it was two particular trades earlier this month that caught the attention of the crypto community.
Ahead of a significant announcement from US President Donald Trump regarding the “Strategic Crypto Reserve” on March 2, the whale made a substantial long position in Ethereum (ETH) and Bitcoin (BTC) with 50X leverage using address 0xe4d3. This strategic move raised eyebrows and led to rampant speculation among investors, some suggesting possible insider ties to the Trump family or connections to the infamous North Korean Lazarus hacking group.
Following his initial trades, Parker netted a staggering $19 million from a BTC short position executed at 40X leverage through address 0xf3F4. After closing his short position, ZachXBT uncovered Parker’s alleged involvement in cybercrime, commenting, “It’s funny watching CT speculate on the ‘Hyperliquid whale’ when in reality it’s just a cybercriminal gambling with stolen funds.”
Connecting The On-Chain Dots
ZachXBT’s rigorous investigation pinned down four key counterparties linked to the 0xf3f address, including 0xe4d3. He highlighted connections to multiple platforms, such as Roobet, Binance, Gamdom, ChangeNOW, Shuffle, Alphapo, BC Game, and Metawin.
Further analysis revealed that the 0xf3f address had signed a message linked to an X account under the username @qwatio, which seems to have been acquired recently. In response to these claims, the user @qwatio denied any connection to cybercrime and maintained that the profits from the GMX and HL trades were legitimate and traceable on the blockchain.
Despite this defense, ZachXBT asserts that for the $20 million profit claim to hold, control of the associated wallets would be necessary. Intriguingly, one address in the cluster, 0x7ab, was found to have connections to a phishing scam alongside funds from an exploited casino game on Solana.
Ultimately, ZachXBT traced a recent payment from the 0xe4d3 address, leading to a UK phone number that seemingly links back to Parker. He stated,
I tracked down a recent payment from 0xe4d3 to an unnamed person who confirmed they had been paid by the HL trader. They provided a UK phone number used to communicate with them. Public record reveals the name William Parker is likely tied to this number.
ZachXBT concludes that Parker, who has a history of convictions related to fraud, hacking, and gambling, has transformed a substantial initial stake into an impressive $20 million through high-risk leveraged trading. As the investigations continue and more evidence surfaces, the crypto community will be keenly observing how this story unfolds and what implications it holds for the integrity of cryptocurrency trading.
