Glimmer (GLMR) is the native platform token for Moonbeam. It is a utility token, serving the same purpose as ETH serves on Ethereum, plus added Polkadot functionality such as staking and on-chain governance functions.
I think it's bottoming out. Using wave targets points this at around 100%. Don't really care for the coin or its use cases just think it's going to have a huge swing up and back down again.
