The good thing about eth 2.0 is nvidia or amd will have no reason to charge these stupid prices anymore for their gpus. rtx 3900 for 2000 usd? what the hell, a normal 3080 for $999, prices used to be half of what they want at moment.
2000$ for nvidia gpus not because miner..
It actually partly is. Back in 2017 before GPU and ETH mining was a thing, GPUs were dirt cheap compared to the current pricing.
To illustrate, i bought a 1080ti for $750 before it all started - when the mining craze started, the price went even up to $1250 because it kept getting sold out/out-of-stock at lower prices. Why would companies now sell for a lesser amount when people are buying it all up at $1200++? So logically: the demand influences the price - a huge part of demand came/comes from GPU mining farms.
