$EGC is based on a hybrid Pow and Pos consensus, hence this project is both mineable and can be staked to generate passive income. Most of the latest transactions on one of this blockchains explorers shows rewards for stakers, which seem to be a major usecase for $EGC.
EverGreenCoin is focused on making the environment better and supporting similar activities. The project has decent social media presence but still very low activity around the coin.
Apart from mining, staking or holding the coin to support their noble cause, $EGC can also be used for making payments. But its good to know the project has a blocktime of about 180 seconds, not too bad but very slow compared to the top crypto projects by marketcap. If you are in a hurry to send funds, you might have to wait a little.
