All crypto currency is down so this is not something having to do with Ether. When the market cap for all coins increase Ether will follow. Lets not forget what happened just over a month ago when the market cap dropped to 60 billion, all coins took a hit and then most recovered.
Ether is one of the best coins and has a bright future. If someone was waiting to get into Ether I wouldn't wait to long as this might be your last chance.
