Uhhh, no it's their broad statute that covers fraud:
"419. Any person who by any false pretence, and with intent to defraud, obtains from any other person anything capable of being stolen, or induces any other person to deliver to any person anything capable of being stolen, is guilty of a felony, and is liable to imprisonment for three years.
If the thing is of the value of one thousand naira or upwards, he is liable to imprisonment for seven years.
It is immaterial that the thing is obtained or its delivery is induced through the medium of a contract induced by the false pretence.
The offender cannot be arrested without warrant unless found committing the offence
The parent to yours was spot on. The fraud associated with bitcoin et al; is no different than any other really. It's just the globalization of it and the semi-anonymity that makes it ripe for abuse. That's why the whole thing is so silly when people point out the lack or regulations and centralization as a benefit. It's the main neon sign drawback.
