Bitcoin will never end unless we don't have connection anymore.
Bitcoin surely never die, and if we die bitcoin will still remain, if the worlds end bitcoin will still remain in blockchain , internet connection will never die as well this is one of the needs of the entire world. So I Think it's hard to say that bitcoin will die or will end . Maybe if there is so many users will invest in bitcoin , the chance of obtaining bitcoin will becoming much harder and slower than before.
It doesn't look like it's going to end any moment now because more and more people are looking for more knowledge about bitcoin and are thus investing as and when they get to know and this has created a consistent demand for it on the market and in turn given it a consistent growth over the entire year 2017.
