The Nigerian currency is called Naira and means a lot to Ibos. It seems that for some people the Naira is even more important than God. They don't use electronic payment and always pay cash. Nigeria is a cash nation. That is why money permanently comes to the fore. The state doesn't collect many taxes and offers no assistance to its citizens at all. To care about your future lies in the hands of every individual. Whenever the individual needs help the family and friends will support - that is their traditional way, the government does not care.
At celebrations a lot of time is spent for donation. Unlike the Germans who donate secretly the Ibos donate in public. The highest donor would be called out so that he can be sure to get the gratitude and respect of the people.
During occasions like wedding ceremonies or other anniversaries it is tradition that the celebrants must dance. While they are dancing male guests come close and spray money on them. This tradition is one reason why even new banknotes become dirty very soon.
