This maybe a valid point but I think ETH's price, just like most cryptocurrencies, is unpredictable! Perhaps we all knew for sure that the era of ICO's has long been gone but had made a mark for its contribution to ETH's rise to become one of the top cryptocurrency in the industry.

I guess we must also acknowledge Ethereum's strengths such as its smart contract feature, a tested and stable platform and ecosystem able to host a multitude of projects and Dapps  on top of it, and most importantly, its overall network value.

Now I think its too early to speculate a downfall on ETH's price because we will never know what will happen next to this platform and what benefits  it could give us in the future. Imho.
