Should I advise you? This kind of discussion should be written in your local thread for effective discussion.
Agreed. I have no idea what OP is talking about exactly, and as is typical for members here, very little details are supplied as to what's supposed to be the topic.
My thoughts too although, I think OP don’t want a more local view to the thread but rather, a global take on this, a wholistic approach based on what is obtainable everywhere in the world to relate with how its been done in his or her country and what effects is supposed to have.
OP, the design and refacing of a countries currency has been a habitual method that is even constitutional, for some countries is after a decade, some after two decades. There are several reasons why a country redesigns their currency note, it can be for a facelift, it can be to discouraged people that have looted the currency and hoarded it for a very long time, it can as well to be to fight against counterfeit notes that might be out there in circulation.
A very nice argument mate, of course it’s constitutional and these ought yo be done without having so much of a negative impact on the country. Meanwhile, do developing nations and the underdeveloped country really need this? I mean, it takes a lot of money on expenditure and hardly any profit in return.
Although, this be the case when, it’s not done gradually and calls for an immediate flushing of the old currency.
