In my opinion, bitcoin wont die. It wont happen . Because nowadays many people started to prefer bitcoin over fiat currencies because of its wonderful features. Bitcoin's price can crash if many countries ban the usage of bitcoin. Or if any hacking or anything similar to that happens, definitely its price will crash. But it wont die.
And for bitcoins to die the price should go down slowly and eventually die, while here the case is completely opposite, the price is just rising and rising and there are more and more sites and service that now appreciates bitcoins, if I am not wrong a big company named CPA lead started to accept bitcoins as the payment method.
