Wow since 2013, thats freakin awesome. I have started mining eth my self and it has completely changed my life aswell. I have a small system but according to the calculators on the web i should be pulling out about a half of eth per month but of course im going to add some upgrades so that will go up. The funny thing is everytime im on the web or youtube watching mining videos I always ask myself why didnt i start this sooner when eth was 7 bucks. But hey its like they say better late than never lol.
