altcoins always survive. Maybe 3 years later we will use altcoins when we shopping grocery or buy car. I hope new ICOs will be more creative and they will process fast. Because some project has too long process time.
I believe that altcoin will definitely survive. The value of Bitcoin is currently much lower than last year. This is a great opportunity to buy bitcoins for a bargain and buy alt coins at the same time, and I still believe that the value of Bitcoin will skyrocket and the Alt coin value may increase.
