This is a very informative post.
I agree with you...
Talking about the changing world order without talking about a disruptive technology such as Bitcoin is to omit the most critical aspect of the changing world order.
I personally do not see Bitcoin becoming a global reserve currency for the sole reason that it is unstable...
Bitcoin has experienced extreme fluctuations in value and that puts a lot of merchandise tied to it at risk...
World reserve Currencies being tied to the supremacy of a state is the past... And while it would certainly be the case that a lot of history is repeated, disruptive technologies make it impossible to completely repeat history.
