Miner hosting

Mining cryptocurrencies in your home makes sense mainly when you have access to cheap electricity (e.g. from surplus energy from a photovoltaic plant) or when mining along with using the surplus heat to heat your home. In case you do not have access to a source of cheap electricity, we recommend using hosting in our data centre abroad. The cost of electricity is only $0.09/kWh, so with us you can save thousands of Euros a year on your mining operation. We will take care of the purchase, shipping, clearance, initial start-up and setup, and regular maintenance of your miner. So the only thing you have to do is choosing your miner.
