On December 18, 2025, Bitcoin traded at $86,948.17 with a 57.6% dominance, according to Bitbo, after a 73‑day decline from its all‑time high pushed it into its most oversold state since 2023. Derivatives open interest sits near $27.4B, down from over $44B in early October, while repeated drops below $90,000 and swift sell‑offs suggest fragile sentiment.
