Energy consumption of a Bitcoin (BTC, BTH) and VISA transaction as of April 14, 2021

The average energy consumption for one single Bitcoin transaction in 2021 could several hundreds of thousands of VISA card transactions. 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.
