Can we get a sticky regarding this topic? It'd clear up the daily convo on this sub a great deal. **What is ETH 2.0?:** A series of upgrades to the Ethereum network explained [here](https://ethereum.org/en/eth2/). **Do I have to do anything?:** No. This is an update to the network itself, Ether held in your wallet or on an exchange or anywhere else is still the same after the merge. **What will happen to the price?:** Who knows. **When will it be released?:** At some point in the future. ETH2 is series of features/fixes with separate development work and release dates. ETH made the news on Jul 20, 2021; the price series does not cover the 30-day window, so no effect is measured. | ||||||||||
