As others are saying, don't worry too much about it.

If you were to move out of BTC temporarily though, please for the love of God, do not look at ETH as some sort of safe-haven!

ETH may have value, dont' get me wrong, but it is not a store of value or currency. It's a highly speculative token on a DApps platform, that has already shown it's untrustworthy as fuck. Please read about the DAO incident if you haven't.

On top of that, if you're worried about BTC taking a big hit over scaling fears, how are you not concerned with ETH taking a bit hit since it's gone up 40X in the past few months?

If you're looking to the preserve your wealth in USD terms, the only coin right now worth sitting in for a while would be LTC. Right now it is very stable relatively speaking.
