You have a good point but truth is almost all the market is going to face a tough season. Most projects will be dead if no bullrun in mid 2019. Lots of projects already dead. So, it's not only Ethereum for a single reason.
I think you are right mate. It is not only Ethereum that is affected by the downtrend or tough season because all are affected right after Bitcoin's price started to fall. All coins, tokens will also fall like a domino effect. Ethereum is great and has strong community, developers, users and adoption. Here in my country, we can even convert our local fiat currency into Ethereum and vice versa. Ethereum will remain the best Altcoin for me.
