Bitcoin fell below $83,000 during Tuesday trading recovering toward $83,100 on Sept. 30, adding to evidence that the latest rally has lost short-term momentum. The pullback followed an eight-month high near $87,400 reached the previous week, and the asset is now stalling around the $84,000 mark as on-chain analysts watch a critical supply cluster overhead.

Attention is centered on the $84,000–$85,000 area, where Glassnode has identified Bitcoin's largest concentration of long-term-holder supply — coins that have stayed unmoved for an extended period and are often read as a proxy for conviction holders. Profit-taking has also intensified, with short-term traders sitting on their highest unrealized margins since late 2024, and some analysts warn the price could slide to $80,000 if Bitcoin fails to break above its current stalling point.

Bitcoin Falls Back Below the $84K–$85K Supply Cluster

Glassnode's research identifies $84,000–$85,000 as Bitcoin's heaviest long-term-holder cost-basis cluster — the price band where more long-term-held BTC is concentrated than in any other comparable range (source on X). Cost-basis clusters of this kind often act as support or resistance, because holders tend to react when prices return to their entry levels. The zone has therefore become a key technical and on-chain reference after BTC slipped back below it.

Bitcoin traded above the cluster earlier in September. Glassnode's Sept. 23 research noted that price had cleared the area after it acted as a ceiling during much of the year. The latest retreat has put that level back in focus.

Market data place the pullback in context. CoinMarketCap showed Bitcoin near $83,100 on Sept. 30, down roughly 0.8% over 24 hours, after the asset traded around $83,661 the previous day. Bitcoin had reached approximately $87,400 the week before — its highest level in eight months, according to CryptoQuant — before declining more than 3% over the past seven days.

A sustained move back above $85,000 would strengthen the recovery. Failure to reclaim the cluster would shift attention to lower support.

Profit-Taking Reaches Its Highest Level of 2026

A key driver of the decline has been heavy profit-taking by holders. According to CryptoQuant, realized profit-taking — profits actually locked in when coins change hands on-chain — reached a 2026 high of 25,700 BTC on Sept. 22, the largest single-day total of the year (source on X).

Traders' profit margins have also stretched significantly. CryptoQuant data show the on-chain unrealized profit margin has risen to 33%, its highest level since December 2024. Such elevated margins signal that traders have room to take further profits, and they have historically preceded downward selling pressure and price declines.

CryptoQuant analysts now expect a pullback, noting that while the rally is still active, it is already showing cracks and running out of steam.

"Last week's close above the 365-day MA confirmed a bull market, as CryptoQuant's Bitcoin Bull Score Index sits at an extremely bullish 90/100. Yet after an eight-month high of $87.4K, several signals suggest the rally is losing momentum, and a pullback could follow," they wrote.

Analysts Flag $80,000 as the First Support to Watch

CryptoQuant analysts identified $80,000 as the first support level should a pullback occur. While that is not a confirmation, the concern is not far-fetched: open interest — the total value of outstanding derivatives positions — has fallen to its lowest level since March. Leverage was one of the key factors driving Bitcoin higher during this rally, with rising prices triggering billions of dollars in liquidated positions.

Glassnode analysts, however, note that Bitcoin-denominated open interest is now down 20% from its August low, while the price has increased 35% over the same period (source on X). That divergence means leverage no longer plays a major role in price movements.

Even so, Glassnode analysts believe the flagship asset can continue its rally. For that to happen, Bitcoin must break through the current stalling point and hold its price above $85,000.
