Bitcoin’s (CRYPTO: BTC) recovery after a record short squeeze faces a dense supply wall between $81,000 and $86,000 as the key test for continuation, according to a Glassnode report on Thursday.
What Triggered the Rally?
Glassnode analyst Frederik Theissen wrote in the firm’s weekly on-chain report that Aug. 19 produced the largest single-day short liquidation event in Glassnode’s feed since 2019, with 85% of everything liquidated coming from the short side.
The rally consumed 86% of the modelled liquidation clusters in its path, leaving two clear landmarks: a dense shelf of short liquidation levels at $82,000 to $86,000 overhead and a band of long liquidation fuel at $60,500 to $62,400 below.
Futures open interest fell 11% in coin terms during the squeeze, while perpetual funding rates stayed near neutral, showing traders did not chase the rally with fresh leveraged longs.
Glassnode described the move as a stop-cluster flush rather than a crowded long setup.
Why the Move Had Real Money Behind It
The firm noted that U.S. spot Bitcoin ETFs pulled in $2.23 billion over the squeeze window without a single outflow day, the strongest seven-day intake of the year.
Every wallet size category, from small retail holders to the largest institutional accounts, has been accumulating Bitcoin for 20 straight days, the broadest and most sustained buying across all investor groups since late 2024.
Larger institutional custody accounts absorbed 59,100 BTC during that stretch as whale wallets sold into the strength.
What the Supply Wall Actually Looks Like
Glassnode mapped four independent structures converging in the same zone. The first self-custody cost-basis shelf begins at $80,800.
Meanwhile, dealer gamma flips negative at $82,300, meaning market makers shift from absorbing volatility to amplifying it.
The surviving short liquidation shelf extends to $86,000, while long-term holders who sat through the entire drawdown hold supply between $83,000 and $86,000 and are likely to sell near their break-even price.
Moreover, sell orders in the order book grew 41% over the final five days while buy orders fell 32%, a clear sign that sellers are stacking up in that zone ahead of price arriving there.
What Options Are Pricing
The options market prices patience rather than a breakout. The middle 70% of strike-implied outcomes through Sep. 25 spans $69,000 to $89,700, with the median near current spot. Max pain on the two largest upcoming expiries sits at $69,000–$70,000.
| Signal | Level | What It Means |
| Confirmation level | $83,300 | Settled closes above, with ETF intake holding, would signal the supply wall is being absorbed |
| Warning level | $70,000 | Short-Term Holder cost basis; the first downside risk marker |
