What is AHR999?

AHR999 is a BTC dollar-cost-averaging heuristic.

Originally proposed by the Chinese investor 九神. The formula multiplies two ratios: today's close ÷ 200-day moving average, and today's close ÷ log-log fitted fair value. The lower the value, the better the entry.

The four zones on the scale below — bargain, DCA, caution, bubble — are folk thresholds from the community, not part of the formula. Read the methodology for the exact constants, or the FAQ for how people use it.

Bargain < 0.45

DCA 0.45 – 1.20

Caution 1.20 – 3.00

Bubble > 3.00
