hello..
so what you want to say that mining is not profitable anymore?? what if I buy 15000 GH/s lifetime contract for 5 850$ ? is not possible that I earn even double in 1 - 1,5 year ?
Well if you plan to buy a setup for 15000gh/s, things gonna suck huge time.
Genesis Mining is the best option, and you make some return on investment whit a bit of luck.
check my calculation:
http://prntscr.com/94nwaxI buy 15 000 GH/s for 5 850$
daily profit with today btc price is 37.69 $ - GM fee 0.0012$ per GH/s 15 000*0.0012 = 18$ fee ... so daily profit is 37.69 - 18 = 19,69$
is this correct calculation ?
But we do not know if the diff will be in day 6 months.
