Bitcoin never dies, it never will, in my opinion. If you are wondering why, bitcoin is indispensable when there are so many investors and money in it. Its lack of control and decentralization make it an excellent choice.
It's like you're saying that you could predict the market 100% accurate. Honestly, we couldn't ignore the possibility that it might die, or the right thing to say is to be devalued, though I agree that in the near future, Bitcoin will not reach that state, to be called "dead". It's not even new that people will call bitcoin that way because of the bear market. Every time Bitcoin's price dumps all the way down of half of its ATH, they spread FUDs even though they don't own Bitcoin, how ironic.
