Altcoin will survive still have strong altcoin they are next to bitcoin like xlm , monero, ethereum, neo all this coins are ready to compete with bitcoin and will survive it
Those people who says that altcoins will not going to survive doesn't really help in any case. They just make the condition worst. In order to make the altcoin survive, we should support it, invest with it, and live with it. We have the power to control and predict its future. That makes me believe that it will not going to vanish someday.
