Bitcoin has accomplished a lot over the last few years and deserves a lot of credit for it but has not achieved its goal yet. Bitcoin is set to achieve global protection whereby everyone will accept its use in terms of payment methods and apply it to their business and transactions.
No one expect that this Bitcoin will be as big as it is now. In fact, people who had bitcoin before spend it unwisely. It's value just realized when price started to spike. And through out the years, people have seen so much potential and the goal already never ends. The only goal is when all the people around the world will discover and used it as for the day to day basis.
