If altcoins cannot survive in this market, they would not survived until now... You cannot make conclusion just by only see the price in the market. The volume of altcoins in the market is still high. So many peoples still use altcoins either for trading, holding or pay something...
That's positive because there are many altcoins which are having great potential to survive because of its great uses and benefits that may brings to the community. Some example of it are ethereum, bitcoincash and litecoins that until now still exist because of its great potential to help country economic growth like bitcoin platforms has itself.
