Great idea I am also fairly new on steemit. I also use Genesis mining to which I have included a link for https://www.genesis-mining.com/a/800930 use my discount code which is hKA3G9 for a lovely 3% discount.  What I also personally do with some of the earnings from Genesis mining I upgrade my eobot account which is another great site. The link for them is below
