The One Naira Initiative is a Nigerian based Nationwide Initiative to help each other out. It's a platform created so that the citizens of Nigeria can actually help one another as opposed to looking forward to the Government for everything.
The mode of operation is by donations, it's just like your everyday usual contributions to your various cooperative societies. The only difference being that you don't have a specific amount or time for your contributions and it's willful not compulsory. It's people helping each other out after all.
That been said, it's helping yourself by helping others too. You are not saving up donations like your normal contributions but donating to help someone else achieve a better life. This can be to aid their Education or Business or Fund a Start Up or any other thing. Same way others donate towards your own Education or Business.
