What environmental issues? There are more than 5 billions of cars running on fuel and generating carbon dioxide polluting our cities and no one is doing anything about it, You are worried about electricity used by bitcoin network? Anyone mining bitcoin is paying for the electricity they are using and if mining wasn't expensive we could never see a price above $1000
Exactly anybody who talks this shit, just ask if he has a car,
+90% of all btc is mined in china, with free hydro,
fools driving their cars like hamsters in a cage are the cause of most pollution in the western world, already in china, most citys have banned gas motorcycles, and everything is now electric, Kunming for instance, its all silent now, ... very dangerous as a pedestrian as you can't hear them coming
I heard current price for mining electricity one btc in western world is $2500 USD, but 1 btc is worth 50 barrels of oil, and it take 20 in energy to get that one btc, ... thus btc is one of the most energy efficients means of making profit in the western capitalistic world
Most large scale mining operations are near hydro, or thermal,
Most industry generates far more waste in search of profits far less than are found in BTC,
Just think of cost doubling your money in any other industry?? It makes bitcoin look like super environmental friendly, even auto industry is barely 10% ROI, if fact without selling credit-cards, GM would be negative ROI
