Reserve Risk measures the confidence of long-term holders relative to Bitcoin's current price. Low Reserve Risk indicates high holder conviction at a low price, representing an attractive risk-reward entry, while high Reserve Risk signals the opposite.
Reserve Risk measures the confidence of long-term holders relative to Bitcoin's current price. Low Reserve Risk indicates high holder conviction at a low price, representing an attractive risk-reward entry, while high Reserve Risk signals the opposite.
The Reserve Risk indicator was developed by Hans Hauge and quantifies the opportunity cost that long-term holders incur by not selling. It uses a concept called HODL Bank, which accumulates value for every day that coins remain unspent. The more coin-days that accumulate without spending, the higher the HODL Bank grows, representing increasing conviction among holders.
Reserve Risk is calculated by dividing the current price by the HODL Bank (adjusted for total supply). When price is low and long-term holders remain steadfast, Reserve Risk drops to very low levels — these periods offer asymmetric risk-reward because conviction is high but price hasn't caught up. When price surges and holders begin taking profits, the HODL Bank depletes and Reserve Risk rises into the danger zone.
Historically, Reserve Risk below 0.002 has marked excellent multi-month accumulation windows, while readings above 0.02 have coincided with cycle peaks. The beauty of this metric is that it directly measures the behavior of Bitcoin's most informed participants — those who have held through volatility and understand the asset deeply. Their collective decision to hold or sell is a powerful signal.

View Live ToolHODL Bank is a cumulative measure of unspent coin-days across the entire Bitcoin supply. Every day that a coin remains unspent, it adds to the HODL Bank. When coins are finally spent, their accumulated coin-days are removed. A large HODL Bank reflects widespread long-term holding conviction.
Low Reserve Risk occurs when long-term holders are sitting tight despite low prices. This combination of high conviction and depressed price creates an asymmetric opportunity — the holders most familiar with Bitcoin's cycles are signaling that they believe current prices are below fair value.
Reserve Risk typically enters the green buy zone (below 0.002) during the deepest parts of bear markets and early recovery phases. These windows can last several months to over a year, giving patient investors ample time to accumulate at favorable risk-reward ratios.
