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.
agreed, it can take a hit, but cryptocurrencies are here to stay. And the governments know it, so I doubt they will ban it...the sooner they can find a way to regulate it though, the quicker it will become the new standard.
