Great time to check marketplaces for mining GPUs being sold off. They’re still valuable even if used at that high throughput for so long. Similar to a cars engine with highway miles vs city miles driven
Nobody mines with GPUs any more, at least not for any significant blockchain. Bitcoin went to industrial ASICs many, many years ago and Ethereum no longer uses proof-of-work mining at all.
Probably not. The “AS” in ASIC stands for “application-specific”, they are designed to be extremely good at just the one specific purpose that they were meant to be used for and if they’re good at anything else it’s sheer coincidence. In Bitcoin’s case that purpose is applying a particular pattern of SHA-256 hashing to a particular-sized blob of data. I doubt there are other applications for that particular sequence of steps.
ASICs likely get used in mining until they burn out, or until they’re supplanted by new designs that make them uneconomical to run in the face of competition, so they probably just get recycled.
