I would say that paper currency is the greatest scam ever to enslave mankind.
Bankers charge interest for a thing which has been created out of thin air.
The paper currency gradually decreases in its value due to inflation over time.
So naturally people tend to move towards cryptos which are free from inflation and the bankers and big economists once again want to pull back people to the traditional enslaving system.
Now the choice is yours.
Enslavery or Financial Freedom?
Think Wise and Twice.
Paper money is bad, since the end of bretton woods system in 1976, there are some countries that benefit from this situation. Powerful countries that it's currencies are easily traded internationally,obtain the wealth of other countries just by printing paper money. The world must use the same currency. But I think its not a scam, it's just have been manipulated by strong countries.
