This is noticeable and a trend for quite some time. ETH might actually have some inelastic demand by the developers of tokens, so its more resistance to volatility.
All crypto is taking a hit right now, but eth is gaining share.
Somewhat, but it's falling now (within the past hour). Seems like it's not as divorced from Bitcoin's moves as optimists would like.
I was noticing that the other day. I wonder if that's because Ethereum has contract functionality and thus as some intrinsic value to it.
On the other hand, the main application for those contracts is ICOs -- which are themselves primarily a speculative instrument. It's turtles all the way down.
If people start to flee the system I wouldn't imagine any of them is safe from panic, runs etc.
