When you purchase the powers you have them on a continuing basis. Even when you repay expenditures , the purchased powers are continuing working. Besides, you can always take your hardware back.
As long as you have the amount no less than 0.005 BTC you will get the payment daily and automatically. If you don’t want to get payments automatically but to store them to purchase additional powers you can choose the relevant payment mode.
To ensure the high output power our hardware mines different types of crypto-currency at the same time. Then our specialists exchange them for Bitcoin on the best terms. We could have made payments in different crypto-currencies but in this case our users would have to make an exchange on their own and for the most part the final output power could be way below.
As long as we use video cards for mining it is generally agreed to measure their capacity in Kh/s. In fact, the productivity of video cards can be measured according to their cryptographic algorithm. For the capacity rating of video cards we use Scrypt algorithm.
We have introduced a concept of a “Unit” by which we understand the video card Radeon R9 280 X Gigabyte (GV-R928XOC-3GD) that has productivity around 700 Kh/s. From there, if the total capacity is 2 800 Kh/s we consider this as a combined working process of 4 video cards. And if we have your request for hardware purchasing you will get 4 video cards Radeon R9 280X Gigabyte (GV-R928XOC-3GD).
Yes, our customers just get the hardware at wholesale. But our profit is 10% of daily output power and we get this profit as a result of exchanging crypto-currencies for Bitcoin. Therefore the output power of the service is shown with our profit that we earn by exchanging crypto-currencies.
