Cryptocurrency options exchange Deribit stated that Bitcoin's recent price has been suppressed around $90,000, primarily due to a large number of open options contracts concentrated near the current strike price and the approaching large-scale expiration date of January 30th. Deribit pointed out that current market risk exposure is established more through options than highly leveraged futures, with traders tending to use hedging and structured strategies to manage risk. Analysis suggests that the high options trading volume, especially for short-term put options, indicates that funds are still in the market but risk control is becoming stricter, with short-term price movements being more driven by position structure than external news. Data shows that Bitcoin has been fluctuating between $85,000 and $95,000 since mid-November. This Friday will see the expiration of Bitcoin monthly options with a notional value of approximately $8.4 billion, a put/call ratio of 0.54, with the biggest resistance level at $90,000 and the most open contracts concentrated near the $100,000 strike price.
