I think what happened to ethereum cannot be separated from the adverse effects of ICO, because in my opinion only ICOs receive investment using ethereum and now ICO is no longer the era.
Agree, ICO died and it made ETH seem dead, in 2017 we saw the prosperity of the ICO and it helped the ETH price go up by more than $ 1,000 in a short time, And now the IEO has replaced ICO and therefore, there is no reason to help ETH increase prices
