I noticed that one of the big whales (pension-usdt.eth) just closed a massive BTC position with a decent profit of around $505,000. The interesting story here is that this whale had sent $30 million to Hyperliquid earlier, buying 1,000 BTC at an average price of $67,100, which amounts to about $67 million USD. The whale's known strategy is to hold positions for very short periods (about 30 hours on average) with relatively low leverage. What’s notable is that this activity is part of a broader pattern — since October, this whale has made total profits exceeding $23 million by focusing on BTC and ETH. After making these huge profits on the Hyperliquid platform, the whale started transferring funds to other yield-generating markets, and currently has about $22 million lent out on the AAVE platform. This kind of whale activity always reveals opportunities that traders can pay attention to in the market.
