Renowned cryptocurrency market researcher ZachXBT has recently uncovered the identity behind the enigmatic figure known as the “50X Hyperliquid Whale.” The target of his investigation is British national William Parker, formerly known by the pseudonym Alistair Packover. With a history of illicit activities, including fraud and casino robberies, Parker is best known for amassing approximately $20 million through highly leveraged operations on decentralized cryptocurrency platforms.
According to ZachXBT’s report, Parker was traced through a blockchain transaction that was linked to a UK phone number. The criminal had already been convicted of stealing nearly $1 million from two casinos in 2023. Even after his arrest, Parker continued to orchestrate phishing schemes, raising funds that were then channeled into risky trading strategies during times of high market volatility.
Parker was notorious for his leveraged trading that could reach up to 50 times the amount invested. This practice allowed even small favorable movements in the price of cryptocurrencies to result in substantial profits. In one notable event, Parker invested $450 million in Bitcoin with 40 times leverage, earning a return of almost $9.5 million in just one week.
These large-scale trades forced other traders to liquidate, putting downward pressure on cryptocurrency prices and destabilizing the market. Despite the high risks associated with high leverage, Parker demonstrated an uncanny ability to take advantage of rapid market fluctuations, securing significant profits.
Parker’s activities raise critical questions about security and identity in the cryptocurrency space. Platforms like Hyperliquid, which promote transparency by publicly displaying trades, also allow users to remain anonymous, making it harder to police illicit practices. Hyperliquid itself has stated that it is impossible to forge large transactions on its system, a clear allusion to the limits of centralized exchanges.
The Parker investigation reignites debate over the need for stricter regulation of the cryptocurrency industry, questioning ethics and the limits of decentralization. The transparency of blockchain was key to identifying Parker, but it also shows how easy it is for individuals with questionable backgrounds to move large amounts of money.
