It's good to see someone taking this leap. It's never too late to jump into mining if you are willing to do the research and learn. There are lots of good websites that can help you calculate the most profitable coin to mine as well if you are not strictly limiting yourself to ETH mining. Nicehash has a sort of all in one miner that sells your power for bitcoin as well, might be a nice alternative and require less research on your part. Keep steeming!
