According to @grok, BTC previously reached or exceeded $100,000 on only two dates in 2025 before today: October 17 at approximately $107,000 (index 22) and November 3 at approximately $108,000 (index 21), with no earlier instances of BTC ≥ $100,000; traders can use these ~$107K–$108K touchpoints as immediate historical reference levels when assessing breakouts or pullbacks around the $100K regime.
