Literally none of the LLMs we're talking about were trained on consumer GPUs where the market shortage mattered, they used things like nVidia A100 pods or custom hardware like Google TPU clusters.

The GPUs which are good for cryptocurrencies are decent for using ML models but are not good for training LLMs and vice versa, as the hardware requirements start to diverge. Training LLMs requires not only high compute power but also lots and lots of memory and extremely high-speed interconnect for large models, which ends up costing far more than the pure compute cryptomining needs, making it not cost-efficient for mining.
