Previously, in times of crisis, capital works were started to put a nation back to work and stimulate the economy. In recent times, interest rates have been used to control the economy, and in the past, when a country was tied to the gold standard, gold was confiscated and then revalued higher effectively devaluing the underlying currency.
One way to stimulate the economy would be to control how cash works. If Central Banks are successful and ban the use of physical cash, forcing everyone to use digital money, another feature of digital cash could be time erosion.
One way to encourage the public to spend and stimulate the economy is to have a digital currency that erodes in value if it is not spent.
how'd u think it will progress?
