# Using Orca:

* Orca can be used to earn a share of the trading fees on EXPMC.
* The amount of Orca required to earn a share of the trading fees depends on the total amount of Orca held by all users.
* Orca can also be staked to earn additional rewards. To stake Orca, you will need to deposit a certain amount of Orca into your EXPMC account and hold it for a minimum period of time. The amount of Orca required and the minimum holding period may vary.
* You can view your current earnings and the total amount of Orca held by all users in the "Earnings" section of your EXPMC account.
