Bitcoin Options Traders Buy $70K Puts as Bulls Hedge Near-Term Downside Risk

Bitcoin options traders are still leaning bullish overall, but short-term activity has turned more cautious, with put buying picking up around the $70,000 strike as traders hedge against near-term downside risk.

• Open interest: about $37.565 billion
• Calls vs. puts: 57% calls, 43% puts
• 24-hour volume: about $3.663 billion, with puts slightly ahead
• Key hedge zone: heavy activity around the $70,000 put

Bitcoin options markets are sending a pretty classic mixed signal: the bigger picture still looks constructive, but traders are not exactly sitting there with blindfolds on and diamond hands alone. According to Coinglass data as of 12:00 a.m. ET on May 28, Bitcoin options open interest stood at about $37.565 billion, up roughly 0.1% from the previous day’s $37.54 billion. That’s not a dramatic jump, but it does show a market with a lot of money still committed to positioning.

For readers newer to derivatives, open interest is the total number of options contracts still active and not yet closed or expired. Volume is how many contracts changed hands over a given period, such as the last 24 hours. That distinction matters because open interest tells you what traders are holding, while volume tells you what they’re worried about right now.

In this snapshot, the broader structure remains tilted toward upside exposure. Calls accounted for 57% of open interest, while puts made up 43%. A call is generally a bet that Bitcoin will rise, or a hedge against missing upside. A put gives the holder the right to sell at a set price, so it functions like insurance against a drop. Translation: the market still has plenty of bullish baggage, even if some traders are quietly buckling in for turbulence.

That’s where the short-term flow gets interesting. Over the last 24 hours, Bitcoin options volume came in at about $3.663 billion, with puts edging calls 50.36% to 49.64%. That’s only a slight lead, but in derivatives markets, small shifts often matter more than they look. When traders start paying more for puts, they’re not necessarily dumping their bullish views. More often, they’re buying protection without abandoning upside exposure.

Or, put another way: traders want the moonshot, but they also want a seatbelt. Sensible, frankly. Crypto has a long and glorious tradition of punishing anyone who mistakes optimism for risk management.

Deribit dominated volume with about $1.76 billion, followed by Bybit at $845 million, Binance at $580 million, OKX at $441 million, and CME at roughly $47 million. That matters because Deribit remains the main venue for crypto-native Bitcoin options trading and a major center for BTC derivatives price discovery. CME’s presence is still important, but in this snapshot the action is clearly being driven more by crypto-native desks than by traditional finance.

The open interest concentrations also tell a useful story. The largest positions were in the $80,000 call expiring May 29 on Deribit, the $120,000 call expiring Dec. 25 on Deribit, and the $60,000 put expiring Dec. 25 on Deribit. That mix shows traders are not all staring in the same direction. Some are positioning for a push higher in the near term, some are betting on a much larger upside move later in the year, and some are paying for long-dated downside protection in case the market takes a nasty turn.

The most actively traded contracts over the past 24 hours reinforced the defensive tilt. The $70,000 put expiring June 26 led the pack, followed by the $55,000 put expiring Sept. 25 and the $80,000 call expiring June 26. A put at the $70,000 strike means traders are actively insuring against Bitcoin falling below that level before expiration. That strike matters because it acts like a psychological and tactical hedge zone: close enough to current price action to feel relevant, but broad enough to protect against a meaningful wobble.

The prominence of near-dated puts alongside an actively traded upside call points to a two-track strategy. Traders are paying for short-term protection while keeping optionality for a rebound. That’s not bearish capitulation. It’s more like a market saying, “We still like BTC, but we’ve seen this movie before and we know how quickly it can get ugly.”

“Short-term flow tilted defensively.”

“Traders are paying for short-term protection while keeping optionality for a rebound.”

Those lines capture the mood well. The longer-term structure remains bullish, but the near-term tape is more cautious. That split is important because Bitcoin options can often reveal what spot markets are not saying out loud. Spot may look calm, while derivatives traders are already positioning for volatility. When put-heavy volume shows up without a collapse in call-heavy open interest, it usually means the crowd isn’t flipping bearish. It’s just refusing to be stupid about downside risk.

That’s also why the market’s current setup is worth watching for BTC price action. A steady base of open interest with put-heavy short-term activity often suggests longer-term bullish structures remain intact, even as participants brace for potential near-term drawdowns. In plain English: traders are still willing to hold upside exposure, but they also see a decent chance of a shakeout, chop, or fast correction.

This is where a bit of nuance matters. Put buying doesn’t automatically mean panic. Sometimes it’s routine hedging. Sometimes it’s macro caution. Sometimes it’s a desk manager telling the team to stop acting like every green candle is a prophecy. The market snapshot alone can’t tell you exactly why protection is being bought, but it does show that traders are not ignoring the possibility of a short-term flush.

It also helps to keep the venue split in perspective. Deribit’s dominance suggests Bitcoin options remain heavily shaped by crypto-native participation, which tends to be faster, more aggressive, and more sensitive to volatility than traditional finance. CME’s smaller share in this snapshot is a reminder that institutional money is still part of the picture, but it isn’t the whole picture. In BTC derivatives, the native crowd still has a very loud voice.

The bigger takeaway is simple: Bitcoin options markets are still broadly bullish, but traders are hedging near-term downside risk with more urgency than before. That combination often precedes a period of uneasy price action rather than a clean trend. If Bitcoin holds up, those puts may expire as wasted insurance. If BTC stumbles, they’ll look like smart risk management instead of expensive paranoia.

What is Bitcoin options positioning saying right now?

The market is still broadly bullish, but traders are becoming more defensive in the near term and buying protection against a possible drop.

Why is the $70,000 strike getting attention?

A $70,000 put acts like insurance if Bitcoin falls below that level, so heavy activity there suggests traders see that area as an important downside hedge point.

Does put buying mean traders are bearish on Bitcoin?

Not broadly. Calls still make up 57% of open interest, so the longer-term structure remains more bullish than bearish.

What’s the difference between open interest and volume?

Open interest is the number of active contracts still outstanding. Volume is the number of contracts traded over a set period, such as the last 24 hours.

Why does Deribit matter so much?

Deribit is the largest Bitcoin options venue in this data and a major hub for crypto-native hedging and price discovery.

Could this lead to more volatility in BTC?

Yes. Concentrated options activity around short-dated expiries can amplify price swings as those dates approach.

Is the market preparing for a crash?

Not necessarily. The positioning looks more like preparation for uneven price action, with traders hedging against a drawdown while still keeping upside exposure in place.

That’s the honest read: optimism is still there, but so is respect for the downside. Bitcoin options traders are not pretending risk doesn’t exist. They’re pricing it in, which is usually a healthier sign than the kind of delusional one-way bullishness that ends in tears and liquidations.
