Counterfeiting money successfully can be very lucrative, although it is incredibly illegal. Of the methods of counterfeiting, you can either create new bills, or alter current bills to look like higher denominations. The video above was recorded in Vietnam where a shop worker rubs alcohol across the numbers on what is seemingly a $50 bill. It becomes quickly evident, however, that the bill is actually a $10 note made to look like a $50. Other than the obvious wrong president on the bill, the counterfeiting is actually pretty good.
