# Exchange Rate It is crucial to understand the exchange rate to comprehend WaterNeuron fully. It is designed to be fair and simple. It is described with the following formula. $$ exchange\_rate = nicp\_{supply}/neuron\_{6-month\_stake} $$ The exchange rate is updated every time some ICP is spawned from maturity. Staking new ICP for nICP doesn't change the exchange rate. The exchange rate will only have positive growth, which means that at first, you can exchange 1 ICP for 1 nICP. After a while, you can exchange 1 ICP for 0.9 nICP. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
