Remittances are one of the best use cases for bitcoin; my comment at https://news.ycombinator.com/item?id=27448744 goes into more details. Bitcoin mining is mostly a subsidy to renewable energy (fossil fuels are too expensive to make fossil-fueled bitcoin mining profitable), so although I could be wrong, I expect it to ameliorate global warming, not worsen it.
> 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.
It's true that rapid price changes can make fossil-fueled mining temporarily profitable, and things like burning off flare gas are also profitable, but bitcoin mining is already dominated by renewables and becoming progressively more so: https://hbr.org/2021/05/how-much-energy-does-bitcoin-actuall...
I'm sorry I abbreviated this whole explanation so much in my original post that you ended up so confused.
