> fossil fuels are too expensive to make fossil-fueled bitcoin mining profitable This is incoherent. Nothing ties these prices together. If tomorrow the price of BTC goes up 1000x, the price to buy a joule of energy via burning coal doesn't change at all.
The ratio of joules of energy to bitcoin mined isn't fixed; it's varied to keep the rate of bitcoin mining constant, although not from one day to the next. If the price of bitcoin goes up 20% in the next two weeks, then bitcoin mines that would have been running at a 10% loss start running at a 10% profit instead, which increases the hash rate and then the difficulty. This increases the amount of energy (and hardware…
Either energy prices are decoupled from mining rewards, in which case reduced prices of either fossil fuels or renewables (or increased price of BTC) means more profit for miners or energy prices are coupled to mining rewards, in which case changing prices of fossil fuels or renewables means nothing to miners.
Please tell me why mining does not incentivize cheaper fossil fuel energy technology in the same way it supposedly incentivizes cheaper renewable energy technology.
> that you ended up so confused
I am not confused. I've heard this argument 1000 times. It is bogus.
