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).
