Hi,
I present this very interesting company because it offers a service that few offer with excellent conditions
I had been following for a few days but I was waiting for them to insert the payment through PayPal in order to buy and present the service.
The Company is Suanlitou

They sell the machines directly (Miners), at the moment the contracts that were sold-out until a few days ago are available again.

Miners available S9 13T , T9+ 10,5T , L3+, A3.

The machine becomes our property, in case the mining contract is not more profitable, you have the possibility to have it sent or authorized by the company to sell it at market price.
The fees are fairly in line with the competition, the current cost is good 0.071 USD / kW · h
I try then to explain a little bit of everything so that it can be understandable, even I'm studying it for good.
For example this is the formula with which they explain the costs and therefore the daily net profit. There is also a convenient calculator on the home page.
Settlement formula:
Mining gross profit - (Management fee + Electricity cost + Quarterly power failure risk fund) = Net profit. Suppose you have 50T hashrate, and the standard output per 1T is 0.0001538 BTC on Jan 1st 2018, deducting the electricity cost, 6% management fee and 3% quarterly power failure risk fund, the net profit of 1 Th/s is 0.000121062 BTC, so your net profit is 0.000121062 BTC * 50T = 0.0058224 BTC on Jan 1st 2018.
Another service that they perform is to send from them the miner already in our possession, they also do other companies .. I have some scattered around the world and good or bad the costs are aligned with the others that I have even if in this case the current cost is slightly lower.
I bought an S9 with them, I bought with PayPal and the contract will start on May 28th.
For the ref I'm still not clear if they return about 10% (maybe less) of the investment and there is a ceiling for each ref, I asked for clarification that I hope already tomorrow to have.
