Maybe a bitcoin will die in the absence of a bitcoin enthusiast and there's no internet network in the world, in that case maybe bitcoin will die, and nobody can stop it all, even a Satoshi Nakamoto is possible. will not stop that.
Maybe not just internet, in general Bitcoin could disappear if know one is asking for demand of Bitcoin, but if we think for an specific instances Bitcoin could die if the owner is gone, specially if he/she didn't share all the details on how to access their account, that's are some probable cause that can disappear or die bitcoin
