Glassnode Sees Bitcoin (BTC) Put Skew Jump to 8.6%

Options Turn Defensive, Futures Stay Long

Bitcoin (BTC) traders are paying up for downside protection. The 25-delta put skew, the options gauge that shows how expensive puts trade relative to calls, climbed to 8.6% from 5.2% a week earlier, on-chain analytics firm Glassnode reported on Monday, October 19. The gauge is the cleanest read on whether institutional books are insuring against a drop or still paying for upside, and a higher skew means hedging demand against a further slide is building among options desks. Readings of this kind usually precede volatile sessions rather than quiet ones. The futures side of the book leans the other way: the aggregate funding that perpetual buyers paid to hold their longs rose 49.4% over the week to $1.6 million, a real bill for staying bullish. Perpetual funding is the price longs pay to keep leverage on, so a rising total means more committed capital on the bullish side even as protection gets dearer. A funding bill that grows while price drifts lower is the signature of conviction longs holding through weakness. The Bitcoin price stood near $81,300 when the report was compiled, more than 2% below its level a week earlier, and the market has since recovered to roughly $83,500. That split, defensive options against paid-up perp longs, is the report's central finding. Glassnode is measured about the alarm level: the skew has not reached its historical statistical ceiling, so the market reads as wary rather than in the extreme fear that marked earlier drawdowns. The firm frames the setup as a market positioned for turbulence, not one pricing a collapse. What it leaves open is which side pays first if spot moves decisively, and that turns on the $80,000 area Glassnode watches most closely.

Spot flow tells the other half of the story. Glassnode's spot cumulative volume delta, the running tally of aggressive buying against aggressive selling, worsened from -$67 million to -$83.6 million over the week. Sellers, in other words, had the upper hand in the cash market even as derivatives buyers paid up to stay long. Open interest sits near its historical upper bound on both sides of the wider Bitcoin market: options open interest rose 3.1% on the week to $38.6 billion, while futures open interest slipped 0.3% to $36.4 billion. Crowded books cut both ways. They amplify whichever way spot breaks, and they make unwinds faster once a level gives. Holder composition adds to the fragility case. Supply held by short-term holders, the cohort most sensitive to price and least inclined to HODL through a drawdown, has risen to 14.7% of the total, past its historical cap. Supply in profit has fallen to 68.2%, so most coins still sit above their cost basis this far into the current Bitcoin halving cycle. That leaves roughly two coins in three above water, but the direction of travel over the week was down. Glassnode reads the holder shift as fast money taking a larger share of the float, a composition that has historically sharpened swings. The level that matters most is $80,000. Buyers have stepped in there repeatedly since the October decline began, which is why the report treats it as the line between orderly consolidation and something worse. A decisive break would force leveraged longs to unwind, from retail perps to whale accounts, and that mechanical selling could deepen a slide faster than spot flow alone. The calendar adds one more variable: the Federal Open Market Committee meets on October 27-28, a setup covered in our note on the Fed's October 28 decision.

Between $82,416 Support and $84,178 Resistance

Our live monitoring puts Bitcoin (BTC) at $83,484, up 2.5% over 24 hours, back above the $81,300 level the report recorded. Our composite scoring places resistance at $84,178, scored 97/100, and support at $82,416, scoring 90/100, so spot is pinned between two strong bands as the skew climbs. Positioning agrees with the futures read: perp funding runs at 0.0071% and the long/short account ratio stands at 1.40, with 58.4% of accounts long. For the overhead map, an earlier Glassnode resistance study flagged the $87,000-$87,800 band as the volatility trigger. The Bitcoin technical analysis maps both bands in detail. Until one of those levels prints, and with the FOMC outcome and spot ETF flows still ahead, the standing read on the 8.6% skew stays as the report frames it: hedged and long, not yet at its historical ceiling. What would change it is a decisive break of $80,000 or a skew that finally reaches that ceiling.
