Since last year, The first bigbang of bitcoin history so many people was engaged in bitcoin and until right now. I dont think so bitcoin will ends because if there was people who use or trade and invest bitcoin is still alive.Only bitcoin user can say bitcoin ends..
I believe we just need to keep on using it, as long as bitcoins continues to circulate in the market and throughout the internet, more and more people will adapt to it and so as investors and retailers. But knowing bitcoin and its reliability as a currency I think it is self sufficient enough to promote itself. That is why its value is so high nowadays even being not advertised and continuously attacked by the mainstream media.
