On October 15th, according to on-chain analyst Ai Aunty (@ai_9684xtpa), monitored that a mysterious new address 0xc2a...4E5f2 has opened a $140 million BTC short position on Hyperliquid, currently unrealized profit of $1.298 million. The address has $34.8 million in funds in the contract account, with the current margin utilization rate at 79.43%.

Earlier, the address topped up funds this afternoon and opened a 5x short position on BTC, holding 1,240 BTC ($140 million), with an entry price of $112,598 and a liquidation price of $137,695. This address just withdrew this portion of the margin from Crypto.com 10 hours ago, was a new address created just three days ago; and the remaining $21.98 million in ETH in the account was transferred from Hyperunit, with this operation habit similar to the "high-profile exchange of ETH from a BTC ancient whale."
