I think I'm going to buy 4 T9+. I have 4 good coupons.
hashrate /price is good but require double the power.
I am also considering the T9's provided the price right now. What do you mean by double power? Aren't they the same power as S9, but just lower hash rate (and supposedly more stable).
I think he means that as you need same power to have half less hasrate, you need around 2x more power to match S9 hashrate. So it's ok if you have good electricity price.
