I am disappointed with the debate whether bittoine is an environmental disaster or not, whether it is likely to happen or not.
Nobody seems to have to use which perceptions to use. At present, depending on the efficiency ratio for ASIC mining facilities in operation, they consume 35 terawatt hours per year or equivalent to Denmark, or very few, probably close to Bolivia. The launch of the mining pool can be partly blamed for providing information on their operations. SOURCE https://www.coindesk.com/bitcoin-mining-wastes-energy-thats-good-thing/
