On March 20, 2025, blockchain investigator ZachXBT identified William Parker, a UK fraudster, as the so-called 'Hyperliquid whale.' Parker is linked to a $1 million casino theft and has a history of hacking scandals. He reportedly amassed $20 million in profits from highly leveraged crypto trades, including a notable $10 million profit from a 50X leveraged trade executed before a recent announcement related to cryptocurrency by Donald Trump. Parker's trading activities on the Hyperliquid platform have raised concerns due to their association with phishing schemes and previous exploits in the gambling sector. His actions have drawn attention to the risks involved in high-leverage trading in the cryptocurrency market.
