How is the amount of money of one's country changing in time?

Question

The amount of money is the same or is it changing?If it is changing,is it more or less than before and why?
And what factors are influencing this?
I think one factor is the foreign investments,isn't it?

Answer 1

Money will decrease in value due to inflation. The value of money worldwide is constantly in flux. Currency is bought and sold on the open markets which could also have an impact on it's perceived value or buying power. Foreign investments may have some impact on a specific countries currency value, but I don't see this as a major factor. Foreign investment does bring in currency but the ability to bolster the receiving countries currency may not necessarily be impacted to any noticeable degree.
