Well, don't be harsh on me haha. theres literally no investment you can make with 100,000N; I have tried to think about it but i cannot process it thoroughly.

Do you want to go into retail sales? Factor in inflation and low spending power; do you think it is sustainable idea?
Do you want to try crypto currency investment? convert it and its $140+, what are you going to buy with that amount in the crypto space that won;t be funny, btc? eth ?
Do you want to save it into Vbank (one of the best savings bank in the country)? even  at that  savings works best with high deposits

In situations like this with 100k; just buy food or save with vbank (the interest rate would wow you, you can read up on this)
