something like

"The Bitcoin network will be the first and probably the only globally adopted technology that will EVER become net carbon negative."

is a really challenging response to any progressive going on about Bitcoin's "wasteful" energy use. The "Energy use Bad" people are my favorite buttcoiners to crush with logic, facts and reason.

Definitely takes some follow up explanation, but they'll be so confused how you could claim that that they'll more than likely start asking questions and want you to explain the position... gets them into a position of wanting to listen (to argue) but they are still listening instead of waiting to argue their next point of contention.
