Santiment: the crowd plunged into maximum optimism about Bitcoin since 2024

Against the backdrop of BTC growth, bullish sentiment sharply intensified and significantly surpassed bearish sentiment.

• Open interest (the volume of open derivatives contracts) rose by 7.6%, to approximately $156 billion, even despite widespread short liquidations: it means traders are not cooling off—they’re entering new leveraged positions

• A similar FOMO wave on August 19–20 temporarily halted the rally, and on September 21 the biggest spike in bullish sentiment since December 2024 occurred

The crypto market usually punishes the crowd’s synchronized confidence: both excessive fear and excessive optimism most often appear right before a reversal.
