Bitcoin at it's core does what it's supposed to do, be a form of money that isn't under control by a government that can change its value or access with the stroke of a pen.  Smart eople saw it as an opportunity to make money via coordinated manipulation, and the price was way over inflated, that caused greedy people to think they could get rich off it and the price skyrocketed even further.  99% of people owning Bitcoin own it because they think they can sell it for more money later, that's not going to cause stable price action at all.  

Another pump cycle will likely happen.  Too much money to be made for someone not to figure out how to manipulate the price back up and start the mania all over again.
