How and why would the end of bitcoin (and any other cryptocurrency) occur? Value decrease? Legality issues? Different technology/ideas to supersede it?
I think the biggest cause of Bitcoin death is government. When Bitcoin is involved in many illegal activities, the government will not let it work anymore. Besides, the simpler cause is that the Bitcoin organization stops providing and exploiting Bitcoin.
All the above causes are hypotheses. I believe that Bitcoin is not so easy to die
