Worth investing in to companies like hashflare.io or genesis-mining.com?
Hashflare:
During black friday there's discount - 1TH/s for 100$. Maintenance fee for 1 TH/s is 0.4$ == 0.0005 BTC.
1 TH/s gives 85-90000 satoshi - 50000 satoshi MEF = 35000 satoshi profit (0.257809$) * 30 = 7.71$ per month, 7.71*13 ~ 100$. So, ROI is 13 months...
But profit for 1 TH/s would vary during a year. So 90000 satoshi per 1 TH/s might be even lower, right?
Yes, profit will be even lower. Hash rate has grown from 540 PH/s to 1800 PH/s in the last year. At that rate it will take much longer than 13 months for your ROI.
Cloud mining can be profitable and ever well-profitable (some contracts have over 200% profit predictions) but you need to choose company and contracts wisely!
There is lot of scam on this market and ever trustworthy companies can have non-profitable contracts (like it happened with Dash contracts after ASICs for Dash mining were invented).
I have written detailed analytic article about cloud mining - Cloud Mining - FAQ, Profits & Risks .
It's big, detailed and explains most common questions, compare companies on the market and contracts available. There is also interesting profit calculations there which will help to choose wisely.
Definitely, Cloud mining can be profitable and ever well-profitable but you need to choose company and contracts wisely and watch out for the risk involved well in advance.
