The Ahr999 index, a key metric for evaluating Bitcoin's price relative to its long-term value, has fallen below 0.5, approaching the 0.45 mark as of November 21, 2025. This level is often regarded as a 'super cheap' buying opportunity for Bitcoin. Data from Coinglass suggests that an Ahr999 index below 0.45 is a strong signal for increased investment, while the range between 0.45 and 1.2 is considered suitable for dollar-cost averaging strategies.
