Key TakeawaysThe $40,000 Bitcoin put is now the second-largest options position, with ~$490M in notional open interest, signaling strong demand for downside protection.Around $7.3B in BTC options are set to expire on Feb. 27, increasing near-term volatility risk.The $75,000 strike holds ~$566M in open interest and represents the max pain level.Calls still outnumber puts overall, showing traders are hedging crash risk while keeping rebound exposure.Bitcoin derivatives markets are flashing heightened concern about downside risk as traders pile into deep out-of-the-money put options ahead of February’s monthly expiry.The $40,000 put option has surged to become the second-largest strike by open interest, with roughly $490 million in notional value tied to that level. The positioning highlights growing demand for tail-risk protection after Bitcoin’s sharp drawdown from its October highs.Bitcoin has fallen as much as 50% from peak levels and is currently trading near $66,000, prompting traders to hedge against the possibility of another steep leg lower.Heavy February Expiry Looms for Bitcoin OptionsData from Deribit shows that approximately $7.3 billion in Bitcoin options notional value is set to expire on February 27, making positioning into expiry particularly important for short-term price action.Put options function as insurance, paying out if Bitcoin falls below the strike price at expiry. The concentration of open interest at $40,000 suggests that a meaningful segment of the market is preparing for an extreme downside scenario, even if it is not the base case.$75,000 Strike Marks Max Pain LevelWhile crash protection is rising, traders are not fully positioned for collapse.About $566 million in options are clustered at the $75,000 strike, which represents the max pain level — the price at which the greatest number of options would expire worthless.With BTC currently trading below this level, a move higher into expiry would reduce losses for call sellers and option writers.This dynamic creates a tension between downside hedging and upside stabilization going into expiry week.Calls Still Dominate, but Hedging Is RisingDespite the surge in put demand, overall positioning remains balanced:63,547 call contracts vs. 45,914 put contractsPut-to-call ratio: 0.72This indicates that bullish exposure still outweighs bearish bets, but the growing size of lower-strike puts reflects a market that is defensive rather than outright bearish.Traders appear to be maintaining upside exposure in case of a rebound, while simultaneously insuring portfolios against a sharp downside shock.Bottom LineBitcoin options markets are signaling elevated crash anxiety ahead of the Feb. 27 expiry. While traders still lean cautiously bullish overall, the rise of the $40,000 put as a major position underscores a clear shift toward risk management and tail-risk hedging.As expiry approaches, spot price movements could accelerate as dealers rebalance exposure around key strikes — particularly $75,000 on the upside and $40,000 on the downside.
