maybe it's a silly question or remark, but given that the current block gas limit is about 8,000,000 and the average gasPrice is about '15Gwei' ( I roughly looked at the chart "Transaction Count by Gas Price" chart on ethgasstation.info and calculated the average ), then the total amount of dollars a miner can earn from that block is about:
$60 = (15Gwei * 8,000,000(gas limit) * pricePerGweiInDolars(~$0.0..1)).
Or you can also use the gas-price-estimator on that same website, just put 8,000,000 as gas used and slide the slider to the very right, for 20Gwei. For me it's incredibly low compared to the reward he gains from mining the block ( it's currently 3 ETH, right?). I am posting it beacuse I am almost sure I misunderstood something. Can someone clarify, or is the transaction reward indeed so low ? Thanks.
