Yeah most for-profit mining, in terms of big farms, uses renewables to maximise that profit, some cities even invest heavily in renewables to lure in big crypto mining organisations, and the tax gains in countries with the appropriate infrastructure/legislation for crypto can be a big boon.
Small scale scalping is trivial, but the industrial scale, bot powered scalping that can go on with certain launches in various industries of late will be having significant artificial impacts on the markets within which they are active, the tactic of buying up 100's to 1000's of units/tickets/ect at a time and then drip feeding the resale to artificially drive up the price, harms both the creators/sports teams/musicians/ect and ofc the fans, besides bordering very close to market manipulation in many cases, but it's unlikely anyone would ever deem it profitable to chase that one through the courts to test it.
