there are no situation bitcoin will die even the creator of bitcoin they would stop it because many people are getting curious about btc and btc is gaining more popular in any country so there is no possibility that bitcoin will die, erase, gone, disappear in markets many people even me are believe that bitcoin will rise up and all people will amaze on it.
There is actually one, as you know, if there is no internet, bitcoin disappears as well. Because blockchain can't work without internet and it's amust for ongoing system in bitcoin transfers.
If people lose faith in the security of the network for one reason or another then bitcoin could die. no matter how many times i look at the numbers i always have this idea in my head that an address could finally be cracked with a super computer ie one of satoshis old addresses, this would obviously be catastrophic .
