**Bitcoin Completes Largest-Ever Annual Derivatives Settlement** December 26, 2025 | 16:00 UTC+8 Bitcoin wrapped up its largest-ever annual derivatives settlement on Thursday (Dec 26) at 16:00 China Standard Time (UTC+8), with a notional value of ~$23.6 billion and a maximum pain point (max pain) of approximately $96,000. **Pre-Settlement Context**: Thin Christmas holiday liquidity, paired with rising precious metal prices, kept BTC trading sideways between $85k and $90k.
