* Bitcoin incentivises _cheap energy_. If burning coal is 10 times cheaper than renewables, shitcoiners will burn coal
* The renewables that may be built are not built for the greater good, for public usage. Only to mine more coin, to make more money, to make more solar panels, to mine more coins, etc. The carbon cost of these renewables is abysmal.
* The only positive point it _may_ bring would be making renewables cheaper, but considering the shitcoin vultures are trying to go waste electricity from any source, including attempting to screw Iceland over, the likelihood of this happening is close to zero.
