Bitcoin’s formidable $85,000 resistance level may have just weakened. A significant sell wall, a large concentration of sell orders at a specific price, has reportedly been dismantled by buyers, according to a post on X. This development could pave the way for further price appreciation by reducing the overhead supply of sell orders.
Understanding Sell Walls
A sell wall is a technical indicator in cryptocurrency markets representing a substantial cluster of limit sell orders placed at a particular price point. For the price to surpass this level, buyers must absorb all these outstanding sell orders. The larger the sell wall, the more buying pressure is required to break through it.
On-chain analytics firm Glassnode identified a sell wall on the Binance exchange situated between $85,000 and $85,500. This wall had reportedly tripled in size between September 24 and September 30, 2026.
Recent Price Action and Influencing Factors
On September 21, Bitcoin briefly breached the $85,000 mark, reaching an intraday high of approximately $85,248. A portion of this surge was attributed to the liquidation of roughly $648 million in short positions. Short liquidations occur when traders who bet on a price decline are forced to buy back the asset to close their positions, thereby adding to buying pressure during an upward move.
However, after the short squeeze subsided, Bitcoin struggled to maintain its position above $85,000 and subsequently retreated.
Two primary forces contributed to this price pullback. Firstly, demand from U.S. spot Bitcoin Exchange-Traded Funds (ETFs) showed signs of cooling. Net inflows into these ETFs experienced a sharp decline after September 22, reaching a low of just $24 million on September 28.
Secondly, long-term Bitcoin holders began to take profits. Their share of realized profits increased significantly, rising from 34% to 55% in the week ending September 29.
Throughout this period, Bitcoin managed to hold above several key support levels. These include the Short-Term Holder Cost Basis, which hovers around $73,300, and the True Market Mean, located near $77,200.
Key Indicators to Monitor
Several factors will be crucial in determining Bitcoin’s next move.
The first is the sustainability of the sell wall’s removal. Sell walls are composed of limit orders, which can be canceled or repositioned at any time. Therefore, monitoring the order book depth on Binance within the $85,000 to $85,500 range will be important.
The second signal to watch is ETF flows. The significant drop in inflows to $24 million on September 28 highlighted how rapidly institutional demand can fluctuate.
The third factor is the behavior of long-term holders. With their realized profit share at 55%, these long-term investors have been a significant source of supply at current price levels.
The price action on September 21 also offers a cautionary tale. The brief surge above $85,000, partly fueled by liquidations, ultimately proved unsustainable.
On the downside, the True Market Mean near $77,200 and the Short-Term Holder Cost Basis around $73,300 represent critical levels. A sustained break below these points could signal a weakening market structure.
