Very true, most of our country men are skeptical when it comes to things they don't even know in depth, like "it's a scam", "no product, no assurance". We've been too traditional with the ideal "trade" that we're being left out, and could not keep up with the changes happening around us, I commend you for enlightening your friend, same as what I do when one of my friends dish out skeptical remarks regarding crypto currency, I bish slap them with cold hard facts, and some articles of people who regret being a non-believer. regrettably though that some of them are so stubborn only to find them selves regretting every time I bring them over to withdraw some cash outs (from mining).
