Maybe you should wait a moment, there is still not a good time to buy the ETH, it seems to me the price of the ETH will still fall by about 30%, because there are still many ICO team did not sell their ETH token.
Comparing the time you made your comment and the price of ETH that was around $780 and now that the price is $308 after touching $270+ it is accurate to say that the price of Ether actually went down more than 60%. That's serious dip
