You can never really know with crypto currencies, not just them but everything in the future. You see and read all of the great minds on this planet Earth saying that Bitcoin and other digital currencies are the future of the payments, but how do they know? Just because Bill Gates says so doesn't mean that it will truly be like that. Don't get me wrong, I'm totally rooting for that because I have invested a pretty penny into Bitcoin, but everything is just a speculation and conspiracy theories. I will tell you what I would like it to be, but that doesn't mean that it will happen. I'd like Bitcoin to be the one of maybe five digital currencies in the following five years, also the leading coin and its value to be around half a million.
