Deribit CEO Luuk Strijers stated that call options dominate the open interest in this quarterly contract, with a Put/Call open interest ratio of 0.69, indicating that the market had primarily been betting on price increases. Currently, about 55% of the $9.4 billion in call options are in-the-money, with the maximum pain point for BTC options at $75,000. Strijers noted that after the settlement, market makers' hedging activities and the dissipation of Gamma effects could lead to increased short-term BTC volatility, and the market trading range may be readjusted.
