Reply to comment by boife1 in Ethereum’s energy switch saves as much electricity as entire Ireland uses | The success of The Merge concept may now serve as a roadmap to enable a switch from Proof of Work to Proof of Stake in Bitcoin. by chrisdh79

Given how much effort and energy does it take to mine Bitcoin nowadays, mining is pretty much centralized. No, not “anyone” can setup Bitcoin miners.

Enough people can setup individual miners with the same objective or setup a DAO to mine. But still once you got 51% of ether it’s game over not the case with btc pow.

If a single person setups a CPU miner, they have a negligible chance to mine a block. A single GPU slightly increases the chance. An ASIC - even more. But anyway the chance is so small you won’t even cover electricity bill. Because the complexity of “work” that needs to be done is insane.

So you’re proposing for individuals to organize a pool, I wonder why no one did that to try to compete with people that occupy abandoned mines with ASICs.

And if a big bitcoin miner manages a 51% attack, they can just keep doing doublespends until someone else manages to set up more mining machines. If a 51% Ethereum staker does a doublespend, they immediately lose all their stake.
