First, let’s state the obvious: Bitcoin mining uses a lot of electricity, so it’s bad for the environment. Anyone who claims otherwise is either a salesperson or a fool. Arguing that mining is good for the environment because it encourages investment in renewables is like arguing that smoking saves lives by driving cancer research. All of the energy comparisons to the traditional banking system are also foolish. There are various nuances to this debate, but none change the fact that Bitcoin has a significant carbon footprint.
