Despite Bitcoins impressive annualized returns since its inception in 2009, the reality is that the currency is still in its infancy and no one knows whether it will really become globally accepted or whether it will eventually disappear. This uncertainty surrounding Bitcoins future is reflected in its price volatility.
Exactly and still a large number of people believe that the price of bitcoins is being manipulated by the creators and the big holders ( which I agree might not be true ) and hence they can't just trust on it.
I introduced bitcoins to a few friends of mine, well with a personal interest of mine, as I wanted them as referrals for a gambling site, but they simply told me after a week that the price is just increasing and decreasing too much and it seems like a ponzi, now how do I explain them its not.
