Soon enough, only the largest operations could compete. Research shows that, for new miners, the price of a bitcoin needs to be at least $600 to break even if electricity costs are less than $0.10 per kWh. Another change has been geographic. It used to be that miners were distributed all across the globe, but many of the largest operations have centralized in parts of the world with at least one of the two following variables: cheap/free electricity or a cold environment. A significant portion of the electricity cost associated with mining has to do with keeping the mining chips cool. For any computer user, we know this as the loud fan working to keep our CPU cool. If the miners are kept cool due to the environment or electricity costs are not a concern, cooling costs become an afterthought. But what if someone still wanted to mine without those benefits? Presently, the only company releasing new products targeting the average miner is the Shanghai-based Bitmain. It believes that its recently launched Antminer R4 is the easiest way for the hobbyist miner to generate some cryptocurrency. But do the numbers actually work? Before the R4 sold out, it would have cost a home miner $1,635 (plus a hefty whack in shipping) to obtain the miner and a power supply unit. With […]
