The Ethereum mining hash rate is still increasing. That makes me think the miners are very confident.
No, i don't think its because of confidence, everyone wants a money making machine and the most profitable is still eth, just!
However, it has been neck and neck between eth and eth clones and feathercoin since the Dao thing.
(feathercoin has only a small market cap and is not carried by all exchanges).

Oh! if it survives, i will buy it at $2
