Whole LHR\HHR BS might end with Ethereum shifting from PoW (proof of work) to PoS (proof of stake). Then miners would be either forced to move on to other alt coins, which might be that profitable, or at least forced to sell their extra cards which they have hoarded gradually. Second hand cards hitting eBay have the tendency of crashing the whole GPU scalping and overpricing thing. However it's too hard to predict this, since the PoS date of Eth 2.0 has been shifted already from Q3 to Q4 now Q1, 22. Plus Intel Alchemist offering 3070 level of performance will surely disrupt the prices.
This is why I'm now sitting relaxed with my old GTX 1080 Ti, with a playlist of old games I didn't play. Plus several PS titles like GoW, Ghost of Tsushima & RDR1 remaster will be released on PC in 2022. So gamers can hold on a little longer until GPU prices stabilize and focus on buying other components and make do with older GPU in the meantime if they a necessity to build new PC in 2022.
