I am debating if I should buy the 2nd batch, since I have the $250 coupons?! What are you guys doing with the coupons? I have free electricity included in my apartment cost so I would be happy if I could just ROI in half a year. But I am afraid those will become doorstoppers eventually?!
With free electricity and coupon i'd give you the green light....sounds like zcash is not gonna fork now so you'll always have a coin to mine. Even though all the z9 ever made(and the faster more effecient ones coming out) will be on it with you, you should be good with the free power and the low consumption on this device to at least ROI and not get your apartment supervisor angry at the high power bills(for awhile anyway). But yeah this guy will be a big paper weight in 3-6 months, so if you expect your free power situation to change i'd say no.
