Bitcoin FOMO Peaks at Two-Year High After Breaking $87,300

Bitcoin (BTC) broke the $87,300 barrier on Sept. 21, sparking a sharp shift in market psychology toward bullishness. The rally was driven by a large short squeeze, a surge in social‑media optimism, and a notable rise in trading activity.

Short squeeze fuels volume surge

Data from Santiment show that roughly $648 million of short positions were liquidated within 24 hours. The forced buying contributed to a 39% increase in total crypto trading volume, amplifying price gains and encouraging further participation from both retail and institutional traders.

Social sentiment reaches two‑year high

Santiment’s social‑sentiment metrics recorded the strongest positive language concentration since Dec. 2024. The Crypto Fear and Greed Index climbed from 51 to 78 on Sept. 21, moving from neutral territory into the upper “greed” range. Keywords such as “higher,” “bullish,” and “above” dominated social chatter, reversing the extreme fear observed in late June when Bitcoin fell below $60,000.

Leverage and open interest continue to rise

Despite the short‑squeeze‑driven liquidations, open interest grew 7.6% to about $156 billion, indicating that traders are adding fresh leverage rather than de‑risking.

Historical context and caution

Past patterns suggest that extreme social consensus can act as a contrarian signal, often coinciding with local tops or consolidation phases. While the current bullish environment is strong, the risk‑to‑reward balance may be deteriorating as sentiment becomes increasingly crowded.

Outlook

Continued upside would be more convincing if supported by sustained spot‑market demand, stable funding rates, and slower growth in open interest. Conversely, a failure to hold the breakout level amid rising leverage could raise the likelihood of a pullback or broader liquidation cascade.
