Hello!
What do you think? when Ethereum will switch to POS?
What will happen to the price then? Maybe a hard fork will happen and there will still be people who will be able to mine?
Since Ethereum has the mining difficulty to increase over time there will be no need for a hard fork in order to change Ethereum from PoW to PoS. I’m gonna guess that it will probably be a few years until we see PoS in Ethereum, as there does not seem to be any talk of it; although I am really no expert here.
