I don't think that bitcoin will die.... but it could split as per the outline of the main events that could unify or divide bitcoin (
https://www.bloomberg.com/news/articles/2017-07-10/bitcoin-risks-splintering-as-civil-war-enters-critical-month):
By July 21: SegWit2x software is released and supporters begin using it.
July 21 to July 31: The community monitors how many miners deploy SegWit2x:
If more than 80 percent deploy it consistently, that should signal community-wide adoption of SegWit and the avoidance of a split, at least for now.
But if a majority do not deploy, expect anxiety within the community to grow as the focus shifts to the Aug. 1 deadline.
Aug. 1: UASF is deployed by its supporters, who begin checking if bitcoin transactions are compliant with SegWit.
If a majority of miners still do not deploy SegWit2x or otherwise accept SegWit, and if UASF supporters do not back down, then two versions of bitcoin’s blockchain could come into existence: a UASF-backed one where only SegWit transactions are recognized, and another where all trades -- SegWit and non-SegWit -- are recognized.
If a split occurs, bitcoin will likely begin existing on both blockchains in parallel, resulting in two versions of the cryptocurrency. Expect traders to quickly re-price the value of both, likely leading to massive volatility.
so based on these, bitcoin won't die but could split and one chain or both might have devalued coins until one chain becomes more superior than the other.... and so, we'll have to wait and see what'll happen next, just hope for the best.
