Ethereum Expiry on Friday. What's your take?

So there's a large expiry happening on Friday. I'm fairly new to all of this and just starting to wrap my head around the basics. This is a bit beyond that for me. I read a little bit on it and the last time this happened in March, it dipped about 15%, only to shoot back and then some immediately after. Anyone have predictions on what's going to happen or a layman's explanation? Haven't really seen any talk of it around here.
