Eth will stabilize and go up in price after POS, simply because there will be smaller amount of coins produced daily, burn process will still cause deflation, staked eth will remove some coins from daily usage etc....
POS will displace small people from the system, game has become to big for small guys if you don't count in staking pools.
Price correction will come eventually, how long will it take? probably few years.
You should know that most of the PoS coins have failed miserably before and what does Ethereum have beside these others that it will continue to be successful after moving to PoS,nothing.Therefore if Ethereum moves to PoS I give it a few months only before it is completely forgotten from the map of crypto,the fact that Ethereum is so successful beside the problems it solves it is a PoW coin which a lot and I mean a lot of people are mining daily making it as famous as it is.One move away from such system is destined to go bankrupt and fail.
Most of PoS coins you saw already shit from the beginning. Some transit from PoW to PoS because they are already from their last leg. It's all thanks to the 2017 bull run that PoW coins or every coins got boosted so people think they were great and PoS was the problem. Big nope.
Can anyone here show me a great GPU PoW coin that is at the top10 in CMC other than ETH? How about top20? Even top30? See how GPU PoW was now at the last leg except ETH which is also soon to ditch it?
when a GPU POW reach reaches a profitable enough marketcap for ASIC makers, ASIC will take over that GPU POW. that take over happens at the top in CMC.
ETH innovation was the mining algo with the DAG on vram, it restricts ASICs wide margin advantage over GPUs, basically ETH was the first successful coin (that reached the top part of CMC in two market cycles) that resisted ASICs.
GPU POW is always has been the "the early bird mining gear of choice"
GPU POW is the the real shitcoiner secret weapon, an invaluable tool ---> this is an "alpha leak" hehehe
