I'm pretty new to Steem and trying to figure out the best way to use the Steem Dollars, etc too. I moved $50 of my Steem here to try/play with but not sure if that helps me or not yet. You seem to know more than me and I like the way you think so you have my Follow/votes :)
We just assembled a couple rigs for Eth these past couple of months and making little bit...maybe a couple hundred profit each month...With winter we are ok bcz we aren't paying for heat in the house so the free heating is offsetting the electric bill for a few months but not sure where we are going to move them once it starts warming up in the Spring again. We figure it's just as cheap as going through CoinBase/others to switch fiat to Alts. Working on starting a ETN mining pool now.
