Both.  Bitcoin brought blockchain technology more to the open,  but I think blockchain will stay much longer.  It has numerous and diverse areas where this stemming technology can be applied and we haven't even scratched the surface yet.  I am currently reading a project where blockchain technology is applied to better lives of senior citizens in China by providing them healthcare options,  predictions for susceptibility to diseases,  checkups and body parameters monitoring and a whole lot more.  I think this project (HiNounou) is pushing boundaries and helping us see that it isn't only millenials that can use this tech.
