Ethereum has forked and thus implemented changes to their blockchain. ETH reduced their block reward from 3 to 2 Ethereum per block SIGNIFICANTLY reducing miner earnings.
Hey VoskCoin, seems you are wrong about the lower rewards; it has been really well the same as before the fork.
While you are correct that the rewards went from 3 to 2 coins per block, remember that the block time has also changed from 20 seconds down to 12 seconds. So unless you are mining just for one block and then turning off your gpu, the returns are the same. ie. 2/3 rewards x 20/12 time is approximately unchanged.
