I wonder if he knows how to do that since he doesn't seem to be too experienced with Bitcoin or signing messages and stuff. Also, let him enjoy his time if he really had bought Bitcoins and has them in profit, and even if he is lying, what's the harm in that? It's a discussion board and let him discuss his success and happiness even if it's a made up story which I think it isn't.
Actually I have no problem with any achievement of stories from forum members about Bitcoin adoption, but more and more we've seen there's always one thread created in this board about Bitcoin adoption in their local country. That's a way to grab easy merit in this forum, you can check on the other threads if you not believing me.
Yeah there's nothing harm about it, but if it's a made up story I believe any merit sources will click ignore on his profile since he doesn't have a good motive.
