Another closely watched wallet, 0xff84..1d, was last reported holding a 1,411.9 BTC short worth about $89.57 million at an average entry of $63,899.4, after trimming 600 BTC following the CPI release and then reopening part of the trade.

While Coinglass data showed Hyperliquid whale positioning slightly favored shorts, broader derivatives data pointed to stronger buying interest overall, leaving scope for a short squeeze if either position is forced to close.
