I might say yes it could possibly happen since several countries are starting to ban them, BUT, if were gonna keep on promoting btc or advertising them and teach more poeple to use it we could still empower btc and help btc to regain its value.
It is nearly impossible or you can say out of question for bitcoin to die. The massive support it is having all over the globe, will not let it die or even disappear for a while. Bitcoin is not banned by all countries, some powerfula nd highly developed countries are with it.
