Has anyone done any serious studies on electricity consumption due to cryptocurrency related activities like mining? Possibly with comparison between different currencies and feasibility of maintaining such consumption? Is there an argument to be made for or against them in the context of global warming?
Well if you are talking about mining activity, is it profitable or not will depend on the price of coins be mined,
so we can be comparation the coins will be mined with other coins which are most profitable.
There are impact with global warming related activity mining but there are not banning activity mining all of countries.
