I think we will see a lot more capitulation than late 2018 if/when ETH goes to PoS. At least in 2018, it was a lot slower. But PoS will be like the revenue dropping by 95% overnight. It will be so bad that even miners with 3 cent power will be unprofitable. That's when the real selloff would start. I wouldn't be surprised if RTX 3090's will cost just $500!
No matter how much truth you tell them, they will never learn unless they go through the process, 3090's could go for even less than 500 usd, very few people mine at loss, most will sell and will not have demand to keep gpus at msrp, bear market is the opposite of bull market, in bull market, coin is king, in bear market, fiat is king and will take time for things get back to normal again, this is still pre bear market because manipulators want to trap more people yet close to top.
The way you think is out of this world and yea you are always on point, I am glad I knew what I was heading for when I built my mining rigs, I don't have any intention of selling even if a 60MH turn 0.2$, what I lost is dollar value and I will keep mining and holding till another bull season gets here, my 100$ after few months of mining can turn 2000$ again.
