This year, ethereum is not as popular as in 2017-2018 because this year there are so many different things. from ICO who are no longer interested and people are investing in IEO.
Those are both dumb investments in my opinion, especially when compared to a winner like Eth. I cannot wait until Eth goes proof of stake, because that should draw in many more investors than are currently present in the market. Right now I'm accumulating Eth in anticipation of this.
For now, I expect the Ethereum 2.0 platform to generate initial hype just like most of these projects do, but the issue will be how successful;
Well of course, but this is true of all major changes like what's happening with Eth. There's no way to tell how successful they're going to be until they're put in place. We're going to have to wait and see, but I think the changes will be huge.
