The answer seems obvious to me. Bitcoin was created as an experiment, and to exploit the creativity of the creative programmers. It was given to us with various caps and restrictions to prevent it ever becoming the dominant payment service in the world. The creators were the central banks and financial elite, and they kept back a million Bitcoin as a security for future manipulation and control, or maybe it was just an investment. The project has been massively successful, and is now being used by the financial organisations for their own purposes. We are lucky to be riding on the tail of this success, and will be able to reap the benefits as it starts to find  its planned level.
