Bitcoin's recent price action reflects a tightly defined range, and on-chain data from Glassnode is providing the supporting detail. The analytics firm's latest reports, "Squeeze into Supply" and "Doubt at the Boundaries," describe a market boxed in between a supportive floor below and an increasingly difficult overhead ceiling.

The setup traces back to August 19, when Bitcoin recorded its largest single-day short liquidation event in dollar terms since 2019. The move was followed by a 26% rally that consumed roughly 86% of the available liquidation fuel, leaving behind a persistent pocket of residual short liquidations between $82K and $86K. Events of this scale matter beyond the immediate move: large liquidation cascades tend to reset positioning across leveraged futures markets, and the residual pockets they leave behind often mark the levels where price later accelerates or stalls, which is precisely the dynamic Glassnode's analysis tracks here.

The supply map Bitcoin is trading against

Glassnode's analysis identifies two key zones anchoring Bitcoin's current range. On the downside, an accumulation floor sits between $62K and $65K, built up by both long-term and short-term holders who acquired coins at those levels. On the upside, long-term holder supply is densely clustered between $83K and $86K, forming a natural ceiling. This kind of cost-basis mapping is a staple of on-chain analysis: because Bitcoin's ledger records acquisition levels, analysts can estimate where large cohorts are positioned and, by extension, where supply is most likely to be offered or defended.

The $81K to $86K band is a convergence point where multiple market dynamics overlap: self-custody cost-basis shelves, dealer gamma flips, and long-term holder breakeven points all intersect within this narrow zone. Gamma flips refer to conditions in the options market where dealers, who are typically short gamma, shift to long gamma and begin hedging in a price-stabilizing direction — meaning the options market and the spot cost-basis structure are both pointing at the same narrow band as a decision point.

One particularly dense node sits around $80K to $82K, where approximately 8% of Bitcoin's total supply is concentrated. The largest single accumulation cluster, roughly 5% of supply, is located at $80K itself.

The liquidation landscape after the squeeze

The August 19 short squeeze was dramatic by any measure. Even after consuming 86% of the liquidation fuel, the pressure was not eliminated entirely. A dense region of residual short liquidations remains between $82K and $86K, representing both potential fuel for a further rally and a zone where market makers are likely positioned defensively.

Profitability signals rising sell-side pressure

The share of Bitcoin supply held in profit rose from 65% in late May to 68% by late August. Rising in-profit supply is a common precursor of increased sell-side activity, since holders sitting on gains historically become more inclined to realize profits as price approaches their cost basis or major resistance. As of early September, the price has stalled just below the overhead supply zone, unable to generate enough momentum to push through the $83K to $86K cluster.

What this means for Bitcoin's near-term trajectory

Bitcoin is trading between clearly defined boundaries, with the $62K to $65K accumulation floor providing downside support and the $83K to $86K supply zone capping upside moves. For the ceiling to break, Bitcoin would need to absorb the remaining 14% of short liquidation fuel in the $82K to $86K range while simultaneously overcoming profit-taking from long-term holders reaching breakeven. The 8% supply concentration between $80K and $82K acts as a waypoint: how Bitcoin behaves at that level will likely indicate whether a serious attempt at the upper range is underway or whether another rejection is forming.
