Do you think someday bitcoin will end or will be replace by other cryptocurrencies?
Is it too late to invest?
Is there a chance that bitcoin will be down?
Look at you man, the way you asking itself tells the story of bitcoin. No, there is no way that bitcoin will come to end because bitcoin is increasing in the first place. There is no currency other than bitcoin which will be worth multi billion dollar market cap which bitcoin is having. So there are less chances of happening that. The money doesn't go off from the market in single shot so bitcoin stays as it is forever.
