WOW
There in Mongolia are 3 Million of People, how they will become job related to cryptocurrency?
If the current currency solutions available to the typical Mongolian are cumbersome, expensive, or un-safe, then it is perfectly sensible to expect that 'hundreds or thousands of jobs' could be created by the availability of a better solution, and in a population of 3 million it is probably a low-ball estimate.
After studying thing for a time, my belief is that most monetary solutions available to most typical citizens of most nations are designed and implemented by people who are using their creation to their own advantage. That does not preclude the solution being useful to the average citizen and it makes practical sense to engineer this to a degree, but the focus is going to be to confer advantage to those who own the system and those who 'work for the owners of the system.'
Of course we are currently in a situation where there is kind of a world-wide 'reserve currency' system in use. Namely, the U.S. dollar (also sometimes referred to, with some good reasons, as the 'petrodollar'.) This is what I've studied the most, and I believe that my assertions about the motivation and design of this solution are as stated above are at least significantly valid. Many countries, and particularly those which are targeted for the exploitation of their natural resources, have subservient solutions which are inevitably designed to benefit the more 'global' solution. An observable artifact tends to be interest in a nation on the part of such entities as the IMF, World Bank, etc.
I would caution that 'the petrodollar' is by no means the worst possible solution and people should think hard before abandoning it for the next thing which comes along. I suspect that the petrodollar is on it's last legs and the proverbial 'powers that be' are both fairly well aware of this and have been working on replacement plans for a while. It is a near certainty that the replacement plans will favor the designers and tie up some of the loose ends which they find bothersome, cumbersome, and inefficient for their purposes in our current solution(s). This will probably be the defining feature of 'globalism', or at least a very big aspect of it.
