Global Bitcoin (BTC, BTH) energy consumption up until October 19, 2021

Bitcoin's annualized footprint in electricity consumption reached an all-time high in June 2021, now believed to be higher than the power consumption of Finland. This according to a source that tries to estimate the energy consumption of both Bitcoin (BTC) as well as Bitcoin (BTH). It does by assuming that miner costs and income are the same thing: The higher the miner income, the more powerful machinery it can support. Essentially, the source first calculates how much miners earn, then estimates how much of this income is spent on electricity and how much per kWH, to finally be converted into consumption figures. The main reason this figure is an estimate, is due to the decentralized nature of Bitcoin or cryptocurrencies in general: There is no central authority that tracks how many computers there are or where miners submit figures.
