Bitcoin is not money, it's just a virtual currency that is not backed up by anything but users. In a short time he managed to develop very well, but the future is in doubt.
It is a wonder if there exists any major difference between money and currency other than the fact currency is one form of money among other forms of money. It was back in the days that we used to have money backed by gold for instance, but these days, we are having absolutely nothing to back money. From the Peso, Rand and Dollar,etc, it is plain air that is behind them and that explains why the governments across the globe are able to go on printing spree whensoever they feel like it and much more reason why inflation has now become such a huge monster every nation is battling with.
