Garrett Jin, founder of fraudulent cryptocurrency exchange BitForex and an agent linked to a group described as a BTC OG insider whale, is tied to the largest on-chain Bitcoin contract long and the largest on-chain ZEC contract short. TradingBeats, formerly Hyperinsight, reported on Aug. 22 that the address held a 5x-leveraged long of 1,270 BTC valued at about $97.9 million, with an unrealized profit of $1.35 million, while simultaneously shorting 32,760 ZEC with 2x leverage, a position worth about $25.97 million and showing an unrealized loss of $11.43 million. The Bitcoin long, tracked on Hyperliquid and earlier reported near 1,268 BTC and about $97 million, had previously swung from more than $22 million in unrealized losses to gains above $500,000 as Bitcoin rose. TradingBeats said the long was opened on May 20 at an average price of $76,117 and had paid $1.41 million in funding fees.
