I think Ethereum and Litecoin will be the 2 altcoin that could survive this Cryptocurrency market as it has been used in my daily life, this makes investors completely reassured about this 2 altcoin as it Being pumped very well
I agree with you
But there is one more longest coin in Cryptocurrency market that is dogecoin
The price is very stable.
But all atlcoin may survive in the marketcap so why are you worried about? If we still using altcoins so it is possible will survive and still going on our market because they're believe those coins. We must did something lucrative in our altcoin to make it big and be still exist in our digital currency.
