I don't quite understand why you're worried. I think you should think about the fact that your relative is already an adult and has the right to choose a hobby. By the way, football is a normal male hobby. If he makes money, then he understands how everything works in sports betting. I can give you a link to 1xbet-apk-nigeria.com. This is a new sports betting site in Nigeria. I use it myself for extra income and entertainment. Maybe your brother will be interested in it too. And you will show that you appreciate his hobbies.
