I am not a gamer
Not sure where you read that, but it doesn't really make any sense. Businesses selling PC hardware don't care who you are and what you are going to use your hardware for as long as you just pay for your stuff. Their only intention is to sell as many products as possible, and if there is whatever store not willing to sell hardware to miners, which I can't even imagine, then it's the biggest shit store ever. Crypto mining has made the GPU manufacturers make more money than they ever would in current times, and especially so because of the fact that PC gaming is only going backwards due to consoles offering much more value for your money. Nvidia stock price was like $22 back in 2015, and hovers around $230 right now -- numbers speak for themselves.
