Bitcoin whale linked to Galaxy Digital builds 1,660-BTC long position

A Bitcoin whale address identified as 0x66f8, previously linked by Onchain Lens to more than $290 million in Bitcoin purchases through Galaxy Digital last year, has expanded its bullish exposure. The wallet earlier received 1,001 BTC worth about $64 million and now holds a 1,660 BTC long position on Hyperliquid valued at about $107 million to $107.36 million, making it the decentralized derivatives platform’s largest position after a long gap. HyperliquidNews said the trade showed about $4.09 million in equity, implying roughly 30x leverage, with unrealized profit of about $944,800. The liquidation price was reported at $63,123 in one account and $63,127 in another, leaving only about a 2.2% buffer below Bitcoin’s price. The activity points to a high-conviction bullish bet, though whale transfers and derivatives positioning can also reflect leverage, hedging, custody movements or broader trading strategies rather than simple spot accumulation alone.
