Bitcoins

       Bitcoins are the digital currency which are held in digital wallet. Transactions are taken over internet and digital certificates are used.These are produced by a computer program that solves mathematical problems.

      Bitcoin can be used to buy things electronically. In that sense, it’s like conventional dollars, euros, or yen, which are also traded digitally.

      However, bitcoin’s most important characteristic, and the thing that makes it different to conventional money, is that it is decentralized. No single institution controls the bitcoin network. This puts some people at ease, because it means that a large bank can’t control their money.
