An old parable said that making predictions is like driving at night. What you can see is limited. It depends on the reach of the headlamp. That said, we can only make rather accurate prediction for a short period, maybe less than five years. More than that, the light cannot reach the road, thus only darkness.
No one knows the end of Bitcoin, or will it end/continue? What I can say is just in less than five years, there's a strong probability that Bitcoin will still exist.
