Bitcoin is a novel idea that will have its run until it becomes too popular.
The value of bitcoin is that it offers an exclusivity with value. Where most users of the cryptocurrency believe its available to all and can’t understand why more people don’ t get on board, they forget the major barrier to entry : access. When the internet came out, with AOL and dial up etc. It was middle to upper income families that had this luxury. Stock rose faster than Bitcoins value in the last 10 years. Millionaires were created overnight. However, as more and businesses, ie. Kinkos, etc. made it available to the masses, suddenly the barriers to accessing the internet became less and competition flourished. Technology then improved as if overnight. Cell phones, cable etc. The world became smaller and stock in internet services cooled off.

Ultimately bitcoin will be extremely valuable due to its limited amount and early adopters holding on. However, the cryptocurrency era will begin. Just like the internet, technology will move at lightning speed to accommodate the demand, once everyone has access to cryptocurrency. Altcoins, steemit , and reputable coins will triumph. Persons will be able to find a vendor for their currency because everyone will have access.
