Mystery Whale 0xb31 Makes Move Again: $560 Million Long Position Bets on BTC/ETH/SOL

【Blockchain Rhythm】An old player has new moves again.

In the past 4 hours, that mysterious address marked 0xb31 suddenly gained momentum—opening long positions on BTC and SOL simultaneously, and continuously adding more. Now, his BTC long position has accumulated to $91.83 million, with a cost basis of $91,500, and a paper profit of $3.5 million (up 1.5%). SOL is even more aggressive, with a position of $13.63 million, an average price of $135, and an unrealized gain of 9%, bringing in $600,000.

But that’s not all.

ETH is the real highlight. This guy has placed a bunch of buy orders in the $3030 to $3150 range, pushing the total to $92.7 million. Last night at 11 PM, when the price just touched $3190, he added another long position. Currently, ETH holdings have expanded to $452 million, with a cost basis of $3179, and $7.25 million in profits on paper (up 8%).

Adding up these three cryptocurrencies’ longs? Total holdings reach $560 million. This number exceeds his $500 million BTC short position opened before the market crash on October 11.

The source of funds is also clear. From the evening of December 7 to the morning of December 8, he transferred $70 million from a major exchange wallet to Hyperliquid in batches, then opened a 5x leveraged ETH long position at a cost basis of $3048. On the 10th, he added another $50 million to increase his position, and today, he投入了1.1亿美元.

This 0xb31 is not an ordinary retail investor. He once held over 50,000 BTC, remaining silent for a full 8 years, then gradually swapped some of his BTC for ETH. Even more mysteriously, his timing often aligns with policy shifts—just hours before the big drop on October 11, he preemptively set up a $500 million BTC short position, ultimately earning nearly $100 million. Garrett Jin, CEO of BitForex, said this address is connected to one of their clients.

Did he sense something again this time?
