In theory, there is a remote possibility, but on practice we can see that btc is just getting better every time and the community is increasing. Since people keep using it, btc will not die.
I think bitcoin will disappear or not it depends on the users. I thought for sure users continue to use the bitcoin bitcoin will not die or dissapear
