only the strongest altr will survive. Etheruem, litecoin perhaps will survive because the community is emotionally attached to it, and the dev is very operative.Altcoins have come to stay just like bitcoins but there are a few that are undoubtedly going to stand the test of time based on good reasons and the level of development.
Agree. Only the altcoins with a strong community and development are most likely to survive in the future. As of today, there are a wide array of altcoins which deliver promising features, and most of all, strong community support. This applies to coins especially in the top 10 ranks in market cap, but there are other which are outside that range which have managed to deliver the goods over the course of years.
As such, I believe that altcoins like Ethereum, Litecoin, Dash, Monero, NEO, Cardano, Gamecredits, and ZCash will most likely survive for many years to come. They have real uses cases in the mainstream world, and once they implement scalability upgrades, then I'm sure that they'll increase in usage and popularity within a short time frame. Technology is changing fast, and only those coins which can keep with the latest standards will be the ones that will make strides in the future. Just my thoughts
