There are various business you can get into as a coper that will fetch you money. I will highlight some here

Online Network Business: ONB are so many out there today. Those that are fully Fiat currency base and those in crypto currency. As a youth Corp member, you have access to hundreds of like mind who are ready to go into network business with you once they see the genuineness in it. ONB is the most lucrative business any one with proper mind can get into and make a significant difference before the end of the service year.
However, ONB need a proper check, a proper research to know which is good enough to put your money into. You wouldn't want you or your friends to lose their money. I have a corper friend who never had any experience in network business before but he has made well over a million naira from investing in one of these ONB. He started with as little as 8500 naira September this year. He is truly a testimony.

Agric Product stocking: instead of saving up your alawi, why not organise 10 like minds to contribute 5k each, ensure you collect your early and invest it in stocking agric products. Around February March this year, palm oil sells for 4500 naira in my place. Today, it's 22000 naira.
5000 naira then will buy 11 gallons of palm oil. If you sell it a month ago, you will have 2420000 naira.
This is just palm oil, what about yams, groundnut, etc.

Online importation business: Despite the dollar naira problem, you can still invest in importation business as a youth Corp. You just have to create a network of friends. Know what they need, get to aliexpress, eBay, wholesale, etc and find them, know their prices, convert to dollar, introduce it to them and add your own profit and import it for them.
