^ They should give incentives for using CBDC, I think more will try it at least.
Nigeria has cheaper products than other countries have. They can live decently with $200 a week. Although it's enough, it's still a limitation and can be inconvenient to someone who wants to transact huge amounts in cash for businesses. All countries have restrictions on withdrawals of money but this I guess is where they know who in the society is richer and they can come up with statistics.
An average Nigerian citizen earns less than that ($200) as a monthly salary so for to spend wisely it is hard to squander that amount weekly. Concerning things been cheap in Nigeria, I will agree with you that some stuffs here are cheap majorly because we are the sole producers, example is the Agricultural produce when compared to countries that do not grow this stuffs. But when compared to the minimum wage they receive as salary, it cannot curtail the expenses not to talk of other bills to payed. So in a nutshell what is earned to what is bought doesn't makes this stuff cheap. A bag of Rice is ₦50,000 which is above what people earn, so you could see its still hard living off with the little earned.
