Ethereum - earn % annual yield

Ethereum will distribute 80% of block rewards via proof-of-stake for block validation, starting with the Casper FFG release that will likely come out in 4th quarter 2018. You must stake a minimum of 1500 ETH to receive staking rewards.
We are not currently running a Ethereum node. We are assessing demand to determine which validator pools make the most sense . If you hold and might be interested in using our validator services, reach out to us.
