Bitcoin is a crypto currency and worldwide payment system. It is the first decentralized digital currency as the system works without a central Bank or single administrator.

header 1) No one single entity controls this currency

       Confusing? Yeah most people think too so at first. The general concept of currency and money is that a bank controls it , that there are rises and falls in it's value based on the global market, and that you can physically hold it. Bitcoin defies all of these. It is, in fact , controlled by everyone who uses Bitcoin as the software used for this currency logs and validates activities of the bitcoins across the globe

      Did you know why May 22 is celebrated as Bitcoin pizza day ?

          At that time , the worth of 10,000 BTC was $41.

bold3) The inventer of Bitcoin is a mystery

           Yes, that's correct! The inventer of Bitcoin is still unknown.

          Since the inception of Bitcoin in 2009, there have been several speculations about who the father of Bitcoin is.
            The bitcoin white paper was made open to the public under the pseudonym of Satoshi Nakamoto. The identity of "Satoshi" is still a mystery yet to be solved.

Some even suggest that Samsung , Toshiba, Nakamichi , and Motorola together created Bitcoin.
