As the crypto market extends its slide, the BTC OG Insider Whale (0xb31) shows a widening floating loss, now around $49.5 million against a total exposure near $680 million and a margin reserve of roughly $48.36 million. The book leans heavily into ETH and BTC longs: a 5x ETH Long with a notional of $564 million, entries near $3,167, and a floating loss of about $39.81 million (−36%), plus a liquidation price around $2,078; a 5x BTC Long at $85.96 million with an average $91,500, and a floating loss of roughly $5.46 million (−32%); and a 20x SOL Long totaling around $31.52 million, $137 average, with a floating loss near $2.81 million (−178%).

During December 7–8, transfers from Binance to Hyperliquid totaled about $70 million, followed by a fresh 5x ETH long entry at $3,048. A subsequent $50 million infusion on December 10 and another $110 million on December 12 increased exposure. There have been no new openings or closings today.

The BTC OG Insider Whale has a documented history of substantial, market-moving trades, including BTC-to-ETH rebalancing. Industry observers note the address is linked to some clients, a claim echoed by Garrett Jin, CEO of BitForex.
