Bitcoin’s rally toward $87,000 has triggered a dramatic change in cryptocurrency market sentiment. After weeks of uncertainty, traders are increasingly talking about higher prices, while bearish commentary is being drowned out by bullish expectations.
According to a chart shared by on-chain analytics platform Santiment, bullish crypto commentary surged on September 21 to its highest level since December 2024.
The enthusiasm follows a powerful Bitcoin recovery, accompanied by substantial short liquidations and rising trading activity. However, the same data raises an important question: has the market become too optimistic too quickly?
What you'll learn 👉
Bitcoin FOMO Reaches Its Highest Level Since December 2024
Santiment’s chart tracks social media commentary containing bullish and bearish language alongside Bitcoin’s price.
The red bars represent bullish discussions, while the blue bars track bearish commentary. The green line shows Bitcoin’s price over the same period.
Three episodes stand out.
In late June, when Bitcoin fell below $60,000, bearish commentary surged. The chart records particularly large waves of fear between June 21 and June 30, illustrating how quickly negative sentiment intensified as prices declined.
The opposite occurred around August 19–20. A burst of bullish commentary accompanied Bitcoin’s recovery, but the rally subsequently stalled.
The latest reading is even more striking.
Source: Santiment chart supplied with the post. These are social-volume readings, not percentages of investors who are bullish or bearish.
The bullish reading reached 954, compared with 269 for bearish commentary, as Bitcoin traded near $86,700.
That is roughly 3.5 bullish mentions for every bearish mention within the chart’s tracked language categories.
Santiment identifies this as the largest spike in bullish commentary since December 2024.
The comparison is significant because it shows that optimism has reached an unusually elevated level. However, social media activity does not represent a scientific survey of all cryptocurrency investors, and a sentiment extreme cannot reliably identify the exact moment a market will reverse.
Short Squeeze Adds Fuel to Bitcoin’s Rally
The sentiment surge coincided with a wave of forced buying across the cryptocurrency market.
According to the market figures accompanying the analysis, approximately $648 million in bearish crypto positions were liquidated over 24 hours, while total cryptocurrency trading volume increased by 39%.
When traders open short positions, they generally benefit from falling prices. If the market rises instead, their positions can be liquidated, forcing those trades to close.
That process can accelerate an existing rally as buy orders generated by short closures add to other market demand.
The combination of rising prices, heavy short liquidations and greater trading activity helps explain why the recovery became so rapid.
But liquidations alone cannot establish how much of Bitcoin’s advance came from genuine spot buying rather than derivatives activity.
They also create a potential problem for traders entering after the largest move has already occurred: the forced buying that helped propel prices higher may not continue at the same pace.
Rising Open Interest Raises Another Warning
Despite the reported $648 million in short liquidations, total cryptocurrency open interest increased by 7.6% to approximately $156 billion, according to the figures accompanying the post.
Open interest measures outstanding derivatives contracts. When it rises, it indicates that more positions are being opened than closed overall.
The increase therefore points to continued participation in leveraged trading even after a substantial liquidation event.
However, rising open interest does not prove that traders are overwhelmingly opening new long positions. Every derivatives contract involves both a long and a short side, and additional information would be needed to determine how positioning has changed.
The concern is that elevated leverage can amplify price movements in either direction.
If Bitcoin continues climbing, leveraged positions could contribute to further volatility. If prices reverse, traders who entered late with excessive leverage may face liquidations of their own.
Santiment’s sentiment data adds another dimension to that risk. The market has moved from pronounced fear in June to unusually strong optimism in September.
Such extremes can sometimes appear near local turning points, but they can also persist during sustained rallies.
Another Crypto Development: Cardano Enters the AI Payments Sector
Beyond Bitcoin’s rally, Cardano has announced a development involving AI-driven payments.
In a September 21 announcement, the Cardano Foundation said Cardano is now part of the official x402 software development kit.
The integration is designed to allow applications and AI agents to pay for API calls using ADA or Cardano native tokens through web requests, without requiring a conventional checkout process.
It creates a potential use case for automated payments, including AI agents purchasing data or computing services.
However, the integration does not establish that substantial payment volume or new demand for ADA has already materialized. Adoption will depend on developers implementing the functionality and users making transactions through it.
The announcement provides a separate example of blockchain infrastructure development taking place while speculative interest across the wider cryptocurrency market increases.
What Does Extreme Bitcoin Optimism Mean for Prices?
Bitcoin’s recovery has delivered a meaningful improvement in market structure, but the latest sentiment reading introduces an additional risk.
The Santiment chart shows that bullish commentary has reached an exceptional level just as Bitcoin approaches $87,000. Heavy short liquidations and rising open interest indicate that derivatives trading has played an important role in the move.
For bulls, sustained buying could allow Bitcoin to consolidate above former resistance and continue its recovery.
For bears, the concern is that traders have become overly confident following a rapid advance, leaving the market vulnerable to a pullback if buying pressure weakens.
The bottom line: Bitcoin’s rally is real, but extreme optimism is not a guarantee of further gains. The next test is whether the market can maintain its recovery after the short squeeze subsides and traders begin reassessing their positions.
