I think a lot of altcoins will survive.
What is future to you? 1 year, 5 years 20 years? and what are you calling survive?
I think all coins who are now over a 1 million marketcap will be also popular in the future, some more some less.
Instead of getting in this never ending debate, i will follow simple rule that coins that are on Poloniex and Bittrex are the well known coins and they have good volume and popularity and they will survive for a long term maybe for 2 to 5 years or even more. For the rest of the coin, if they can go through a year or so, it would be great achievement for them.
