Altcoins never going to be the crypto CURrENCY people say. Only way altcoins survive is when the business USES the token themselves: business must create its own demand or don't have an ICO!

EOS creates demand for itself, so it will not die. GAS has its own demand, it will not die. Kora Network creates its own demand, it will not die. Only ICOs who make you need their token to use their service/business will survive...otherwise, don't buy into an ICO if the token won't sustain itself
