# Changing NERC & ECs The obtained NERC, doesn't matter the way, can be changed by ECs that can be used to make all types of buys inside the Nergame platform, like participate in the events, complete the daily challenges, etc. Also, all the ECs won by the users can be exchanged by NERC at a rate of **150 ECs = 1 NERC**. This rate **can be changed a little bit (-+ \~15%)** in the future to ensure good sustainability**.** --- # 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.
