That sure is a lot of S5's. I'm curious if you are close to ROI on the hashnest S5's. I'm too lazy to do the maths on how long it would take to ROI on the S7's at hashnest.
Not even close to ROI
My average S5 purchase price is 0.001217
BTC GHs 1,405657
BTC for S5
However, S5 possibility to ROI is much greater than the S7 ROI
It all depends on Bitmain behaving, if the BTC price rises.
If Bitmain raise the S7 price, has won all previous S7 buyers. If not , they are all lost. Hashnest S7 price goes down and S7 "never" ROI .
Hashnest S5 market opened in early February.
S5 price In February was close to the 1.8
