I would suggest adding a site like miningrigrentals to your system. Most mining on older, established coins is not going to turn a profit, because of the diff being higher. That comes from the coin being mined for many months or, in this case, years. There are sites, like the one I mentioned, that allow you to rental out time on your rig for BTC. If you sign up on one of these sites, then you mine as usual, pointed to the site. When no one is renting your rig, it is forwarded to whatever URL/Stratum you set on the site. When it is being rented, you receive the rental income.
Another cool thing about a site like this is that you can use the site to change your own mining endpoint, which can be easier for new people that doing it in a connected ASIC. Not pushing any site, just mentioned the one above because it has been around for more than two years that I know of. I really recommend this site.
