Bitcoin is now popular, and many countries have used it for payment purposes. But the way to grow better and more perfect is still very long for Bitcoin to do now. For example there are still some countries that do not trust this work Bitcoin, of course this is a very complicated work for Bitcoin do today. So in my opinion, Bitcoin is not finished yet to achieve its good purpose, so continue the best Bitcoin!
For me, I think bitcoin already reached its goal as you obeserved bitcoin is very popular cryptocurrency investment world wide and it uses also as payment in online transactions with the highest number of investors.
It is true that it is used for exchanges and acquisitions and known by many but has never yet reached its true value
