The service is not in the best shape right now: at the end of summer, they disabled the affiliate program, which was bringing me decent money, and the terms of cooperation changed. Nevertheless, mining continues, and payouts come on time, so I can't call it a scam. I've been working with this service since the summer of 2016, and I was intrigued by the opportunity to start mining on a demo version without any real costs to understand how everything works. Once I figured it out, I bought a one-year contract. I mainly work with bitcoins; the prices for power are slightly above average—around $20 for 100Gh, and the choice of power is limited to SHA256 only. The profitability is 170% per year. I invested $500, and in the summer of 2017, I received over $800, not counting the income from the affiliate program, which was almost $200. Occasionally, I had to contact support throughout the year, and they responded quickly in Russian and always helped.
