Bitcoin is approaching a significant cost-basis confluence zone between $88,400 and $89,200, creating a pivotal test for mid-term holders. CryptoQuant analyst Darkfost identifies that investors holding for 18 months to two years have an average cost basis of $88,350, while the 6-to-12-month cohort sits at $89,200. Darkfost emphasizes that these levels represent average entry prices rather than technical support or resistance, serving primarily to identify risk zones where emotional reactions may occur. The 6-to-12-month holder group has remained largely unprofitable for nearly a year, with some positions established near market peaks. This convergence could trigger selling from impatient investors or accumulation from those averaging down, potentially disrupting Bitcoin's recent upward momentum.
