Looks like the ATH difficulty is to much for some miners and early hashrate projections ca. - 5%.
Also, Foundry USA, an investement of the Digital Currency Group which is now seeking to raise 1 bn, lost ca. 10% share of hashrate form the peak of 28%. Could be due to solvency fears.
The most telling chart is the record amount of selling in the industrialized mining bussiness (https://nitter.net/caprioleio/status/1594671729917714437). It's up 400%!
IMO the HODLing strategy of a lot of those miners is reason for this but stronger miners will emerge and pick up those cheap ASICs.
Any other theories why hashrate and Foundry are dropping?
