First advise to give in to introduce them to this forum, because this is a platform intended by the bitcoin creator to engaged all bitcoin users to discuss all around the world, from here, they will be guided the right way, advised and given useful links and kits to start up with as a newbie, provided that they are willing to learn,
I love the fact that you added provided they are willing to learn, because not everyone to me you invite to the forum, for them not to be a nuisance to the naija local board and the forum at large, by loitering everywhere with AI garbage post.
But honestly speaking, if a newbie wants to learn about Bitcoin without getting scammed, doing his or her own research is the best, so that he wouldn't be ignorant on certain things, because ignorance is what mostly gets newbie investor scammed.
And finally, another thing that would be helpful is if he have an experience Bitcoin investor around, that would show him through all the necessary steps to navigate his or her way around.
