Crypto miners buy a slab of silicon, plug it in, and its profitable. If this weren't the case, no one would mine it. Cryptocurrency is a fungus; either it will die, or it will eat up as much electricity & high-powered silicon as miners can get their hands on, diverting both from more economically interesting and productive applications. If I have one or two computers; that's enough. I don't need anymore. There is never "enough" computers for miners; they will always want more, because more electricity & computers means more money.

This is not theoretical. This is happening. Its destroying any service which dares to offer free tiers of generic compute. Its had a significant impact on a global silicon shortage the likes of which we've never seen, impacting products from graphics cards and work computers to cars and defense hardware.

That's it; there's no other correct opinion, only incorrect ones. If you support cryptocurrency, you support the environmental collapse of our planet. We don't need it; its die-hard supporters are either profit-motivated or have nothing beyond a grade-school understanding of historical macroeconomic trends and the broad, undeniably negative impact immutable currencies like Gold & Silver had on the average person's standard of living during economic downturns.
