If u can show them clear evidence about what u have achieved from BTC and how long u hodl the BTC in your wallet to arrived in that amount of money you made, I guess dey will show interest in BTC because dey will enjoy BTC network through transaction. Do u no say many people in the country no BTC? yes, some of the children in the country no BTC, just that dey don't have money to invest in BTC, and before dey go reach 18 years old dey will definitely show interest in BTC investment because by then dey will have money on their own to buy BTC and hodl.

Based on the insecurity wey dey our country, I will not encourage anyone to make people show interest in BTC because u don't no who u will tell about BTC that will set u up with bad guys because our people believe say bitcoiners are millionaires in the country.
