Cryptocurrency also known as Bitcoin PR is a digital currency created in 2009. It follows the ideas set out in a white paper by the mysterious Satoshi Nakamoto, whose true identity has yet to be verified. Bitcoin offers the promise of lower transaction fees than traditional online payment mechanisms and is operated by a decentralized authority, unlike government-issued currencies.
It is the first digital currency, which can also be used to buy merchandise anonymously. And, it is said that soon it can become a world wide economy. So, after having such type of advantages, why would not one prefer it? I think it just depends on you, like in what way you think about the currency.
