Reserve Risk is defined as price / HODL Bank. It is used to assess the confidence of long-term holders relative to the price of the native coin at any given point in time. When confidence is high and price is low, there is an attractive risk/reward to invest (Reserve Risk is low). When confidence is low and price is high then risk/reward is unattractive at that time (Reserve Risk is high).

This is the Point-in-Time (PiT) variant of Reserve Risk. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
