not really ethereum is pumped right now and it needs to drop. it is resisting so far because the fear and uncertainty is not yet lifted from the market and gullible investors still think there is no manipulation in ETH markets.

and no ETH will not follow the bitcoin price rises. if bitcoin starts rising today you can kiss your ETH investment goodbye because it is in a bubble and it will be a catastrophic burst.

but sometimes when it is at the bottom there is lots of manipulations to keep it from going to hell.
see this https://bitcointalk.org/index.php?topic=1724160.0 and try to remember it next time.
