Well there is one of the way we can think. But unrestricted flow of money thorough out the world will also have drastic affect on the market. There may be less impact for already large economy but for the country with lower economy there will be problem.
Now at the moment the nation that have lower GDP have very restrictive way of flowing money outside the country which make except for genuine business transaction the flow of money going out side the country is narrowed. As a result of that the currency devaluation is controlled. If large sum of money move unrestricted the investment in the cryptocurrency will definitely increase and at the moment the cryptocurrency can not be bought with in those country the money from those country will flow out side the country so fast that there may be a problem.
That is our theory may be it will never happen but we think there is a chance and those triggers will affect the whole world. That is our main thinking.
