It is a proof that the price of altcoins is normally unstable. It will fall but hang on because it will definitely rise up again. This is a good news for investors.
I also think that ETH is a strong coin with big market capitalization in addition to Bitcoin and aggressive potential. I think he is currently the Ethereum trend is not that good but do not have to worry about it because it has good potential and can easily show up. All new coins such as ICO and altcoin available using the Ethereum platform are a big advantage for Ethereum.
