I think it is simply a correction. This is normal happenings in financial markets.
Bitcoin is causing some uneasiness going into User Activated Soft Fork.
Ethereum is going to go through growing pains especially with the influx of all the ICO's triggering sell orders. Ethereum is still in it's infancy and I hope that greed and over saturation of ICO's does not make people loose belief in this amazing technology. I am holding long and you guys should too. And people stop investing in ICO's simply because you want a Ferrari . You are hurting the blockchain. Get out if you cant handle the volatility . Invest in a ICO that you sincerely believe in. I fell in love with crypto because of the fascinating technology!
