Its still true and shows one of many issues with bitcoin.

Based on bitcoin cryptobros, you need a certain amount of independent miners for the 'quality' of bitcoins. A bitcoin miner if its a state, can operate with a loss a lot longer if not even infinit, than the decentralized normal people (who do not exist anyway).

It also creates a lot of pressure on miners if you do not run your gpus, yuou are also at a loss, which can break the mining for everyone if too many in parallel go offline, than go olnine again because difficulty droped to much.

And if it becomes to volatile, no one wants to risk it anymore

Bitcoin hasn't been viably mineable on GPUs for over ten years. It requires specialized hardware.

As such, mining is typically restricted to those with massive capital investment in a single-purpose, so you really won't see random offloading and onloading of that capacity. As long as it's marginally profitable (with capital investment being a sunk cost, this is the price where it's more than ongoing costs), those miners will keep their machines running.

The original idea was for every single person out there to mine bitcoins on their own computers. Bitcoin screwed that up by allowing big corporations to push out the smaller players. Their big purpose built hardware increased mining difficulty to the point mere mortals need not even apply. Mining on GPUs? Nope, you need purpose built ASICs for this.

Monero is the only cryptocurrency today that's at least trying to implement the original "one CPU, one vote" vision but nobody really cares about it since number doesn't go up.
