ECOS Mining is a bunch of rubbish. Their web page stinks & doesnt work half the time, the calculator that you use to find profitable contracts to buy is wrong most of the time, support doesnt help you at all & are a bunch of liars, ECOS is about the hard sell, they always want you to buy more contracts or equipment.<br/><br/>They do pay out in the end but to get paid is a real hassle, money disappears from your wallet, nothing is clear on how much you mine or make per day. Most of the positive comments on Trust Pilot & other sites are false. Save yourself the hassle & find a decent professional company to invest in, ECOS is not professional or decent at all.<br/><br/>I have 3 different contracts with ECOS & Im sorry I invested my money with ECOS. If I could get a refund I would, but I cant.
