Ethereum isn't dead but ICO is about to.
But as the market goes up again, this will give the idea to every ICO that there's going to be a big pump for these too on 2019.
This is something that I have been thinking as well, icos and their developers were taking advantage of the lack of regulation in the market but the huge amount of coins and fraud going on in the market has made governments of the world realize what it's happening, so it is likely that there is not going to be any country in which there is not going to be a strong regulation against icos.
Firstly, it not every countries have allow the use of crypto currencies so if we are talking about ICOs regulation such countries shouldn't be included.
Meanwhile, Ethereum is not dead but there's possibility that ICOs will be dead due to the statement by the US SEC but there's chance that they will end up regulating ICOs as you said.
