Bitcoin mining all switched over to custom ASICs long ago, and is barely profitable even on that hardware. The GPUs that were used for Ethereum mining can't compete.
- wongarsu 4y agoFor some more background: bitcoin's POW is basically just sha256, which was trivial to port first to GPUs and then to custom hardware. That makes mining a bigger up-front investment and thus more centralized, which is why almost all later coins chose POWs that aren't easy to speed up with ASICs
