Bitcoins are mined using computer calculations. This operation can generate individual profits but the cost is exobitant in energy consumption.
If you want make money mining bitcoin, you have a choice of two options. Your first option is to pay a company to do the mining for you. This process usually takes place in vast warehouses (called “farms”), stacked with huge computers that buzz day and night, with their fans whirring furiously and cables everywhere, in settings that seem to hail from a Philip K. Dick dystopia. The second option is to start mining at home. To do so, you’ll need specialised computers that cost a few thousand euros each, the right software and the technical know-how to put it all together.
