I know it’s “fact” but is there any actual proof that demand during/from Covid and new generation of hardware worthy of upgrading to isn’t the actual increased demand for GPUs rather than miners? I “know” miners are buying cards up and converting energy to heat while many would list climate change as important to them... but is there any proof it’s miners driving the demand?
