Summary:
Bitcoin futures open interest fell from $38.0B to $36.6B in the week to October 4, per Glassnode.
Spot taker flow flipped from -$102.8M to +$33.2M, while ETF demand cooled sharply.
Hot Capital Share rose to 19.5% and the short-to-long-term holder ratio to 14.2%, keeping the market price-sensitive.
Sustained spot buying is the next test of whether the rally can absorb active supply.
Glassnode, published Monday, October 5, put aggregate futures open interest at $36.6 billion, down from $38.0 billion a week earlier, a 3.8% decline. Open interest measures the notional value of outstanding contracts. It does not show how much leverage sits behind each position or how much collateral backs it, so a lower number does not automatically mean a safer market.
The remaining exposure is still near the upper end of Glassnode's historical range. That is the first caveat. The derivatives market got lighter, not light.
Bitcoin was trading around $86,000 on Monday, in the upper part of a range it has held for two weeks, after a Sunday rally pushed the weekly close about 2% higher. Bitcoin live data showed it near $85,600 on Tuesday.
Why open interest fell while bullish demand did not
Here is where the data gets interesting. Long-side funding payments rose from about $926,000 to $1.5 million, a 57.3% jump. Funding is what traders pay each other to hold perpetual positions. When longs pay more, bullish demand in perpetuals is stronger. So open interest shrank while appetite for leveraged upside grew. Those two signals can coexist when traders close positions but the remaining ones lean more heavily long.
Options told a similar story with a different explanation. Options open interest dropped from $42.2 billion to $36.0 billion, down 14.7%, after the quarterly expiry. Glassnode called that a scheduled reset in positioning, not a sign of stress. Its read on the options skew points the same way: the 25-delta skew eased from 2.5% to 2.1%, which means demand for downside protection cooled.
Spot buyers took over
The spot market changed hands. Spot cumulative volume delta, which tracks whether buyers or sellers are the more aggressive side of trades, moved from negative $102.8 million to positive $33.2 million. The perpetual-market equivalent improved from negative $940.1 million to negative $87.4 million, so aggressive selling there faded sharply, though it did not turn positive.
Source was careful on this point, and so are we: the shift shows who was more aggressive, not how much new money came in. It is a better sign than the week before, but it is not proof of fresh capital.
The part that worries analysts: recently active coins
The more cautious half of the report concerns who holds the coins. Glassnode's Hot Capital Share rose from 18.9% to 19.5%. This metric tracks how much of Bitcoin's realized value sits in coins that moved recently, using a three-month window according to Glassnode's own glossary. The ratio of short-term holder supply to long-term holder supply climbed from 13.7% to 14.2%, which means about 14 units of short-term supply for every 100 units held by long-term holders.
Why does that matter? Younger coin cohorts tend to spend more readily when volatility picks up. Their growing weight in the market keeps price sensitivity high. There is a nuance, though. Activity alone cannot tell you whether the new money is first-time investors or an established holder moving old coins. When dormant coins move, their age resets and they count as recent supply, even if the owner has held Bitcoin for years.
Glassnode's wider read is that on-chain activity, new capital and profit-taking all run hot. Daily active addresses rose 6.1% to about 675,800, transfer volume sits above its high band, and roughly 73.6% of supply is in profit. Realized profit dominates realized losses, with the ratio moving from 1.2 to 1.3.
ETF demand cooled
Institutions are not leading this move. Weekly US spot Bitcoin ETF netflow is still positive at $208.1 million, but that is 87.7% lower than the week before, when ETF demand surged. Weekly ETF trading volume fell 11.8% to $10.8 billion, just above its low band. ETF MVRV, which reflects how much unrealized profit the average ETF holder carries, rose to 1.5, above its high band.
Bitnxt's view
We read this as a healthier-looking market with the same underlying question. Lower open interest and a spot flow flip are good news on their own. A smaller derivatives footprint means fewer forced liquidations if price turns, and we have seen what long liquidations do to a thin market. Our own coverage of $164 million in long liquidations earlier this week is a reminder of how quickly that can happen.
But the strength of this setup depends on one thing: spot demand has to keep showing up. Right now, ETF inflows have cooled, spot volume is flat at about $5.9 billion a day, and the market is leaning on a thinner base of buyers while more of the supply belongs to people who are quick to sell. That is not a bearish forecast. It is a reminder that a price near $86,000 with 73.6% of supply in profit gives a lot of holders a reason to take gains if momentum fades.
Our view is simple. Watch two things over the next week: whether spot CVD stays positive, and whether ETF flows pick up again. If both hold, the open interest drop looks like healthy deleveraging. If spot selling returns while profits stay stretched, the same data starts to look like fragility.
What to watch next
Whether spot CVD stays positive in Glassnode's next weekly report
Whether ETF flows rebuild after last week's cooldown
Futures open interest moving back toward the top of its range
Hot Capital Share and the short-to-long-term holder ratio, which show how much supply is ready to move
Bitcoin's reaction near $87,000, the level BitNxt flagged earlier
