BitCoin is like the internet. It can't die out, as long as there's people on the network, and still accepting it, it'll stay alive.
Yeah, its living is now with the living of internet , if internet is alive and is working there then it will mean that bitcoin is also there and is not died, bitcoin has a lot of good features and people do not want to reject it and want to benefit from that currency.
i think you are correct, internet is going to be around all the time and i think because of that bitcoin is never going to die, i hope it will destroy banks
