Just came to my mind today. What are the things that could end bitcoin's life? What are the threats that bitcoin could face? Are there famous people who want to end bitcoins aside from the government officials? And how can we avoid and survive those?
You can't do anything to prevent it, really, and there will likely never be a way to actually stop Bitcoin from dying in the normal sense. There will always be something trying to edge Bitcoin into a death spiral and there's nothing that can be done about something like that other than continuing to do what you do already and encouraging others to do the same. bitcoin only dies when everyone else abandons it as well.
