It already has.

Hash rates across the board have dropped dramatically, across all GPU mineable coins. I have several friends who have moved onto shitcoins like ergo and like, RVN, both of which I see exactly 0 future in.

For those interested in how the semi-pro and hobby miners look at the world, look at whattomine.com

There's no rumor about it. Go check your local facebook marketplace, craigslist and similar. If power isn't crazy expensive in your area its likely that there were several hobby miners that are decomissioning rigs super close by wherever it is a given person lives. I have discord contacts on literally every continent who are offloading hardware, some dedicated few who are continuing to build their own data centers worth of insanity.

The most crazy thing I've seen since starting this endeavor was a literal dumpster, like, the size a large department store would use, completely full to the brim of broken down GPU boxes from any manufacturer you care to name, all purchased by 3 people I know well enough to meet up for a beer should I be in there part of the country. Some people have a lot of disposable income, free time, and don't mind tearing up their yards to install 240v lines.
