Hello
Before reading many topics in this forum, because I'm live at Brazil, no way to buy some S7 or S9 or GPU to mine, BTC o ETH whatever ..
Price of electricity is very expensive ... kwh is + or - 9$ per day .. (average)
My question here is: When I talk here about cloud mining, each people indicate to use hashnest.com, but when used cloud mining at cex.io, i did not get good profits, and now, cex.io is not working with cloud mining anymore.
Would it be possible for you to refer me indicate to another cloud mining alternative that can be trusted ?
I have spend a good time to read and calc about values for ROI and found out that it is not a good idea to buy a S7 at hashnest according to these numbers:
initial cost for one s7 = 370$
4860GH/s
operating cost per day: 7.483$
operating cost per week: 52.38$
operating tcost per month: 224.5$
If this site:
https://bitcoinwisdom.com/bitcoin/difficulty and my calculations is correct, to recover the investment of 370$ i would need two months.
Are these numbers correct ?
Is it worth the investment since everiday diffucult increases and ROI decreases ?
Thanks for the help !
That looks right to me but did you remember to properly factor in the change in difficulty ? Will the miners be in operation 24/7 ?
I think the main factor is how long it would take for the miner to get here, remmeber the longer it takes the more money you are losing. You need to factor these things into the equation as well.
