> cryptocurrency mining is mostly done using ASICs Bitcoin mining is mostly only effective with ASICs, but cryptocurrency is more than just Bitcoin.
Bitcoin has maintained at least 60% market dominance year-over-year since its inception (averaging 75% all time dominance). Ethereum (which can be profitably mined using GPUs) has currently 15% dominance, with most of the other top 15 coins not being PoW (except for Litecoin, Bitcoin Cash and Dogecoin, from which only Bitcoin Cash can be mined either with ASICs or GPUs). Also, Ethereum is in the process of moving to PoS.
