10x Research has advised clients to hedge their bullish Bitcoin positions by shorting Ether, countering predictions of a year-end ETH rally. Markus Thielen highlighted several factors influencing this strategy, including a weak outlook for Ether's digital asset treasury, reduced ETH purchases by Bitmine Immersion Technologies, and increasing investor aversion to Ether. The firm noted a rise in Ether put options, while Bitcoin options open interest reached a record $50 billion. The suggested long-BTC/short-ETH strategy aims to protect investors if Bitcoin breaks out of its current sideways trading pattern.
