And I think that's the exact point where the O.P of this thread is driving to, that is, those who only speak of the good side of Bitcoin and not the negative sides so as to create balance in whoever pick interest in it and decide to invest in it. Because I have a friend of mind who approach me last week telling me of his interest to invest the money he intend to use for his traditional marriage in Bitcoin rather than leaving in bank, that like how much profit can he get for  investing $500 after 2 months time. And I just have to be plain to him that Bitcoin is not like a Ponzi scheme where you could invest "X" amount of dollar today and except to earn a reward or profit of "Y" amount in either weekly or monthly, which in most cases likely to end up being a scam. But I was able to tell him that Bitcoin is a volatile digital currency whose price value likely to rise or fall, depending on the demand & supply, and a good option for a long term investment & other benefits, but how much he could make in 2 months time is what I dont know, as he could likely make profit or lose. And since then I'm yet to hear his final decision.
