Almost every discussion about altcoins majorly is centered around ETH, this has taken over the first page of the
https://bitcointalk.org/index.php?board=67.0 section. This goes to show the important of the coin in the space and how much premium is being placed on it. My belief is that ETH will not die and most ICOs will continue to launch on the network. This will make the price to back up as the demand for it will increase.
In your logic, I do not see the answer to your question. It's not a fact that the price for Ethereum will be restored. Projects (ICO) developers sold a lot of coins, it brought down the price. By what means will it rise if ICO will soon play by other rules? I hope, that we passed the stage of chaos in this market.
