ETH could indeed use a fork to revive it's value. There simply is too much going on without much response to the ETH dev team and frankly people are getting tired of waiting for their promises that seem to keep getting moved. 2017 was supposed to be the time for the promised POS algo change and soon 2018 will be over. Will they blow through 2019 without any significant changes as well?
If they made a bigger dag and played around a bit with some other specs it could be only the 1080ti 2080ti and Vega 64 work along with newer gpus coming out as for pos:
POS = piece of shit
Basically POS is putting money in the bank and getting some interest on it.
Why on earth should I risk have 100 or 1000 eth coins sitting to get interest.
Remember since the leader controls the coin he can change rules pretty easy and my 1000 coins getting 1% a month could be at his mercy. Since coin value can tank at any minute.
I rather have 100,000 usd in a cd getting 2 % a year if I want interest.
The bigger DAG solution is new for me, sure it will hit 95%+ of miners, but people will go mad then.
