Right but if you're a gamer and you wanted an AMD card and can't get one because of crypto demand you'll buy an Nvidia card, thus causing demand to spike. Obviously it didn't spike as high as AMD but consumers will feel the shortage if demand spikes over supply, which happened in this case.
I seem to remember the 1070/1070ti/1080 being affected too. The lower and higher end (1060/1080ti) were the main ones to escape
Nvidia as well made “crypto mining” cards that were just a mainline card without video output. I recall a video by LinusTechTips who attempted to get video output from one of them.
There was a time period where pretty much the only gpu you could get was a GTX 1050 Ti. At first it was only AMD cards, right, but things changed after a while.
