I found somewhere idea that Bitcoin mining can affect on ecology. the greater btc's spread - the greater the influence of bitcoin system on ecology. Does someone calculate cumulative kW of all Bitcoin miners? it can become a serious threat in the future. am i right?
I have no idea how it could affect the ecology. In my opinion bitcoin mining is the way more environmentally-friendly than a working banking system with a huge number of printers, computers, cars and etc.
