hi,
i am confused and i need your experiences please
i have two choices
1- bought Antminer S7 from china
it will cost me 1200$ to my country
using it to mine by myself ( i have free electricity )
Hash Rate 4,7 = 7.21$ per day
2- bought 7,5 TH/s from genesis-mining with same price
equal 11,5$ - (0.4*7.5) ( for maintenance ) = 8,5$ per day
what is you choice ?
The obvious choice is the one that makes more money daily.
The smart choice is to not buy any mining hardware or "cloud mining" contracts until after halving (just wait a month).
Difficulty will rise and you will be getting half the reward very soon, you will be waiting forever to ROI.
Why get an S7 when the new S9 is right around the corner?
