The AHR999 Index is a Bitcoin valuation model that combines the 200-day moving average (SMA200) and a long-term logarithmic regression curve to identify price extremes. By comparing the square of Bitcoin's current price against both its accumulation cost and projected growth path, this index helps traders and investors detect historically undervalued or overvalued zones. The AHR999 is especially useful for spotting macro entry and exit points based on BTC price trends and cycle positioning.
