It is not an uncertainty a currency system that is governed and controlled by the government must have total control mechanisms in place. It would be insane and absurd if they did not have those mechanisms for control.
I am not sure what any of this means but if it is true and Brazil is trying something like this, I am sure that it is not going to be the end result, they will keep on working for the end result and we are going to see many things change over course of time. I know that it is going to be not so easy for many people but I feel like it is going to be alright.
The best thing we could see right now is to make sure that we are at a stage where having this kind of result will not be too bad, nations should do this to prevent USDT type of companies not to corner the market. Brazil may not be the one we are looking for but it is not a too low country neither, it can get it heard and be an example for some of the other nations as well.
