These sorts of articles always seem suspect to me. Blame the miners is a great trope. There really aren't any valuable crypto's being mined on CPU/GPU any longer. After ETH switched from PoW to PoS, it decimated the whole mining industry. Nothing else has enough volume to really make a huge dent, so the incentive was destroyed. Sure a few people deep into it can make a few grand a day, but this isn't enough to drive a whole market.
