According to monitoring by Lookonchain, the identity of the mysterious whale address 0x1f25 has been confirmed as X user @AguilaTrades.
Over the past four days, this user transferred 29.85 million USDC from CEX to Hyperliquid to go long on BTC with 20x leverage.
Currently, they have an unrealized loss of over $5.5 million—yet when Bitcoin’s price dropped again, they chose to increase their position and continue going long.
