I was introduced to ECOS about a year ago, when cloud mining was very popular. I tried different services, which ended up getting scammed… And ECOS is still on the market. Try it for yourself, it is a good service. Also, it’s a great place to profit from mining without all the hassles associated with actual mining. So far, no problems with ECOS. I definitely recommend ECOS if you’re interested in mining contracts.Special mention should be made of the support service and user-friendly Account Managers.
