“Ethereum 2.0 is an upcoming set of upgrades to Ethereum that's intended to make it significantly faster, less expensive, and more scalable. As part of the upgrade, participants may stake ETH tokens to help secure the network. In exchange for staking, participants then receive rewards on their staked ETH. Staked ETH (and rewards) can't be unstaked until Ethereum 2.0 fully launches, which most experts estimate will happen between 2022 and 2024.” -Coinbase
