just got a strange email from Bitmain!!! price dropped coupons and double Z9 shippment.. so confused 
Yep same. F this. I'm done mining. Just going to trade. Tired of losing money on buying miners that will take over a year to ROI. I will not get another Asic. The coupon will go straight to the trash bc I am tired of donating to shitmain
Dude, sell the coupon to someone to help recoup losses. Dont throw.
