Our thoughts on IEO and ETH vary. Almost every project uses ERC20 and I think the current is still using ERC20. I'm now not doing anything against ETH, it's not going to make ETH die.
There are those who do long-term investments, so under no circumstances will they sell ETH, before the coin soars high. Maybe if you are a daily trader, you can sell your coins because of the price decreases.
I just hope that Altcoin could be like the year 2017.

i am an ethereum holder and plan to invest long-term or until ethereum returns to what it was in 2017.
just like you, right now i am not doing anything about ethereum other than just waiting for the market to recover and i hope it will happen in the near future.
It's hard to expect an altseason like what happened in 2017 although I also expect it. But buying ethereum at current prices in my opinion is a good decision because ethereum prices are quite low against bitcoin. I think investing long term in ethereum is a safe decision because of its large liquidity and is also widely used as a major currency in many exchangers
