A mysterious crypto trader that made millions trading derivatives this year has been identified as William Parker, a convicted fraudster

A mysterious crypto trader who was identified by blockchain sleuth ZachXBT on Thursday as William Parker, a convicted fraudster, made millions of dollars this year trading derivatives with 50x leverage.

The trader, who was the subject of much speculation in crypto circles after making a huge profit on Donald Trump's crypto announcement, reportedly went long on BTC just before the former president's weekend intervention.

After Trump's announcement, and as the price pump quickly reversed, the trader closed his long position for a profit of $6.8 million, and then went short on BTC, going on to make another $9 million.

All of his positions used 50x leverage - a high risk strategy as it means the liquidation price of a position is close to the entry point.

And it seems as though high risk gambling was this particular trader's speciality, as on-chain data suggests the wallet frequently interacted with Roobet, Gamdom, Shuffle, BC Game, & Metawin accounts - all crypto-based online casinos.

The wallet connected to the trades was set as the drainer fee receiver on a phishing website in January, receiving 17.1K from a phishing draining customer in the same month, ZachXBT revealed.

The investigation then delves into a Solana wallet that was the first to interact with the trader's wallet. This SOL wallet made withdrawals from four casinos following an input validation exploit on a casino game. ZachXBT reached out to these casinos which provided him with a Telegram account of the user.

That Telegram account yielded verification that the trader was active on-chain at the same time as posting in derivatives trading chats on Telegram.

ZachXBT went one step further — finding a payment sent by the trader to an unnamed person on the HyperLiquid exchange. That transaction led to the uncovering of a phone number linked to a person called William Parker.

Last year, Parker was convicted and sentenced to 2 1/2 years in jail in Finland for stealing 1 million euros ($1 million) from two casinos in 2023. He was previously served time in 2010 in the U.K. for multiple fraud charges related to hacking and gambling.
