Some set of people in Nigeria really don't understand what bitcoin is all about they still feel Bitcoin is same thing as Ponzi scheme, when ever you tell some set of people about Bitcoin especially those around 40 to 50 years they just thinks it's a scam and they will tell you not to talk about such a thing again.
I won't actually blame them because a lot of Ponzi schemes has really dealt with them especially that age bracket of 40 and 50 years above, I know some set of people of that age that took some ponzi scheme so serious and they where even referring people and it later crash so telling them anything related to online investment is just totally a scam to them.
However those young people in Nigeria that are still seeing Bitcoin as a scam are very low in teams of hustling, as a Nigeria youth you should know about Bitcoin and how it works, the young people that I will understand if they don't know about Bitcoin is those that are staying in the village but as long as you are a youth staying in Nigeria cities or town you should know about Bitcoin.
People should just learn how to do research about things it helps a lot.
