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?
Bro, do not think about that at the moment. The popularity of bitcoin and crypto currency, only gaining momentum, not taking into account the situation on the market at the moment. Just live here and now. 
Not thinking about your future is not the best course of action, is it? We all hope for the best but you have to always consider your eventual exit strategies, because if the market does crash eventually, you will not be able to wish it away.
