Miners are feeling worry about that now. They can still mine ethereum but this will not be last long. Ethereum may go for POS as soon as possible and this will be forcing miners to move from ethereum to the another chain. I hate that miners were creating the inflation and controlling the governance. I hope that the holders would be able to give contribution to the network once POS will be fully launched.
They will regret that why they dumped their Ethereum in 2017, 2018 and especially in 2019.
They were able to mine Ethereum very easily in 2017 but price was $50 to $100 only. Now price is $3900 and the difficulty is considerable higher. They get significant less mining rewards.
I can not know what others think of Ethereum but I reserve 2 ETH in my portfolio. I believe in the future of blockchain industry in which Bitcoin and Ethereum will be leaders.
I regret that I did not buy Bitcoin when it was $3000 in 2017 so now I will not repeat that mistake.
