These days Altcoins have a hard time. But I don't think Altcoin will die forever. King of Altcoins, Ethereum also very bad when comparing the previous peak. But I believe they will survive. Many people these days collect Ethereum for future. There are 90% of ICOs runs in Ethereum blockchain. So with this huge dump, they attempt the sell their collected Ethereum funds. I believe that action also caused to make this worst. Another thing is many Ethereum ICOs don't have a chance to protect their tokens because of the Etherdelta and Folkdelta. Many people sell tokens very cheap prices there. So ICOs also have a bad time because of them.
