Thanks for being very optimistic about Bitcoin. I believe that Bitcoin can be contributing a lot for the society especially in the world of finance and yes this can be doing some good impact for the global economy. However, just like any man-made invention we should not fully rely on only one thing or aspect because the world's problems are so complex and the global economy is not that easy to decipher. In the face of human nature shortcomings, Bitcoin can fall into something which we should be avoided in the first place. Bitcoin still has to surmount the challenge of massive adoption and this is not going to be easy as there can never be a law that can dictate people on what to do and where to go. Certainly, we can never force people to adopt Bitcoin if they don't want to...all of these things here are just voluntary in nature. The speculative fever in 2017 that catapulted Bitcoin into the news and into the consciousness of the many was motivated primarily by "greed" or the possible profits that they (or should I say we) can get and this in itself can be a strength or weakness at the same time. Certainly, it can still be a long, long way before Bitcoin can be a big big force for the global economy and there will always be bumps, humps and challenges along the way.
