I found the hashafare.io to be reliable and profitable. The best contract for the purchase is SHA-256 with a . The second most profitable is Ethereum mining. I suggest not buying a mining contract script. Pay attention to the minimum amount necessary to withdraw funds for each currency.
The only catch is you must have a total of 0.0502 BTC to withdraw. You must purchase a minimum of $185 with a SHA-256 contract to make that possible. Your contract is valid for 1 year. When you withdraw your 0.0502 Bitcoin made with a SHA-256 mining contract, it will be worth roughly $562. This is $ 377 profit or return on investment of 277%. These calculations are done on January 21st, 2018 with bitcoin currently priced at $11,255.
Hashfare.io proves profitable with the value of Bitcoin as it fluctuates up and down. I have a contract of 2.7 TH's and I am able to withdraw, every 5 months, roughly $575 worth of Bitcoin where my money is made back. The next 7 months of my contract is then 100% profit. I suggest Hashflare.io for trustworthy online Cloud mining for everyone!
