At $482 after the coupon, it's really hard not to ROI unless you buy super expensive PSU and have crazy high electric rate.
dont forget you only have about 100 days till the halving.. so maybe not.
I'll have to buy the EVGA 1600W Gold PSU to take care of my S7, that will hurt my bank a little unfortunately lol. :*( I'm in college right now so I'm one of the few fortunate people blessed with free electricity. I might as well have a miner running on the side to recoup back some of my tuition fees. Hehe > Given my situation, I'm not too worried about the long term repercussions of the halving. I was going to invest some money into buying bitcoin directly, but the alternative (mining) seems to be so much more fun and better in the long term.
