The ramifications of the DAO/ETH hack haven't even begun to occur yet.  Wait till the fork happens or fails to happen, the child DAO matures or is overwritten, the lawsuits get filed, and the investors bail if/when they get their precious DAO ether back.  Until then, enjoy the short term ups and downs, but unless you're a day trader trying to make money on the short term moves, stay away.  Ether is not good for long term investing right now, it's far too uncertain.
