Why not ask if cryptocurrency will end? Why these blokes so focused on the "end of Bitcoin" if the mining of the said coin has not been completed yet. It will take more than 100 years from now, before all Bitcoins will be mined. Why hasten the end of Bitcoin? You also mentioned Doge wondering if it will go on top? Goes to show you are not that well versed in Cryptocurrency and the trends. You saw what? A "great downfall"? Ehem, that is called a correction and we Bitcoin traders and investors know that these things happen and we do not panic unlike the weak hands. Are you a weak hand? Talking about the end of Bitcoin makes you look like one.
