The $40,000 put option ahead of February 27 expiration has emerged as one of the most important positions in the Bitcoin market, highlighting strong demand for protection from the downside after a massive selloff.
Options are derivatives that give holders the right, but not the obligation, to buy or sell Bitcoin at a predetermined price before expiration. Put options act as insurance against a decline in price, with a payout if BTC falls below a set strike.
The $40,000 put is the second-highest strike by open interest, with about $490 million of estimated value tied to that level, underscoring the appetite for deep tail-risk hedges. BTC has fallen by as much as 50% from October highs and is now trading around $66,000, with conditions changing across the board as traders hedge against further losses.
Data from Coinbase-owned Dubai-based exchange Deribit shows that about $7.3 billion of the notional value of Bitcoin options is set to expire at the end of the month.
Meanwhile, $566 million sits at the $75,000 strike, which also represents the maximum pain level. Maximum pain refers to the price at which the largest number of options expire worthless, reducing the payout to buyers. With the spot price trading below $75,000, a move higher on expiration could mitigate losses for call sellers.
Although calls outweigh puts overall, with 63,547 call contracts versus 45,914 puts, the situation is not entirely bullish. The put-to-call ratio of 0.72 indicates that upside bets still dominate, but the concentration of large put open interest at lower strikes highlights the clear demand for downside insurance.
Traders maintain the risk of a rebound, but are also hedging the risk of another sharp decline.
