strange really, you never hear about the vast swathes of energy used by the banking sector in various server farms, banks and offices and its impact on the world, its a necessary cost for the system to run. why should only bitcoin be demonised for its necessary energy use

bottom line is things need power and that need is only going to become a bigger issue as things like machine learning and cloud gaming pick up, so rather than gripe about this or that producing xxxx waste lets just focus on producing clean energy so it wont matter
