Only thing nice to see is a company dealing with a 100% pure scam, now mining for more than a year and after a question about the profits;Maintenance fees cover electricity consumption and taking care of mining devices.Maintenance fees are always fixed in USD equvalent and may be calculated by following formula: sum of purchased GH/s x 0.001 USD / 10 GH/s for ever 24 hours.What a scam, brilliant !The maintenance fee is equivalent to the claimed profit.JUST BEWARE !!
