I still don't buy this
tbh, it just doesnt make the economic sense for most miners to buy the latest generation of GPUs...the efficiency isn't there at commercial scale (but they are great for gamers who want to mine overnight!)
Just looking today, mining Ethereum and assuming you have your own large pool of cards, an RTX3090 will net you around $7 per day,
before any electricity/running costs. A Radeon VII will net you around $5.50 for a MUCH lower up front cost. I can buy one of those today, and the
profitability is actually near enough on par with a 3080/90 when you take power usage into account.
