Currently, ethereum is playing hide and seek game looking at how its value is playing currently. Today, it assumes a certain price, another time it will assume another value. Anyway, purchasing some ethereum whiles the price dropped below $200 is a good initiative. You will at all cost earn some profit because, the price of ethereum will surely increase. It is just a matter time.
I agree with amphibian. ETH is a good coin and its best to deposit as much possible while in low because I too think Bitcoin will go up, and perhaps sooner than we think.
