According to the source, BTC is reported to have closed above 100K USD for 170 days, but traders should validate this using CF Benchmarks’ Bitcoin Reference Rate (BRR), the FCA-regulated USD benchmark relied on by institutions (source: CF Benchmarks), and CME Group’s BTC futures daily settlement prices for cross-confirmation (source: CME Group). To avoid venue-specific anomalies, cross-check aggregated spot daily closes through independent market data providers such as Coin Metrics and Kaiko before positioning (sources: Coin Metrics, Kaiko). If the 100K USD close streak is confirmed, treat 100K as primary support and monitor order book depth and options open interest clustering around the 100,000 strike to assess liquidity and gamma dynamics (sources: Kaiko for depth metrics, Deribit for options OI). Key risk triggers include a daily close back below 100K on the BRR benchmark, a breakdown below commonly watched moving averages on regulated reference indices, and rising basis on CME BTC futures that may signal stress (sources: CF Benchmarks, CME Group).
