Cloud mining means that you do not buy a physical mining rig but rather rent computing power from a mining company and get paid according to how much mining power you own. At first, this sounds like a really good idea, since you don’t have to go through all the hassle of buying expensive equipment, storing it, cooling it, and monitoring it. However, it seems that none of these cloud mining sites are profitable. Those that do seem profitable are usually scams that don’t even own any mining equipment; they’re just elaborate Ponzi schemes that will end up running away with your money. What we do at D-Central is hosting services. You own the machine, we own the infrastructure and rent it at a fixed price. If your unit is profitable in market conditions you make all the profits, if not, you take your unit back.
