I want to invest in crypto currencies. Why does your offer preferable instead to invest in own farm?
In case of buying ordinary miners, you need to solve a number of problems: Miners are quite noisy devices and placing them in living quarters will bring a number of problems. In connection with round-the-clock work, miners need a good cooling, due to which miners life service is extended. One miner consumes about 1,4 kW/h on average, which requires a high-quality wiring in place. When installing more than 3 miners, the question arises of carrying out a separate wiring, since the standard household wiring are not designed for power about 4 to 6 kW. Miners are periodically pending. Miners need to be tuned to the maximum speed and certain amount of time need to be spent for maintenance.
Cloud mining is solving all these problems for you.
