Bitcoin is a digital or virtual currency which allows people to send money online instantly but much more importantly anonymously. To start using Bitcoin you will first need to sign up for a free Bitcoin Wallet at one of the many sites that offer one, and once you have a Bitcoin Wallet then you can purchase Bitcoins and start using them as the way you move money around online.
Many US facing betting sites, bingo, casino and poker sites now accept Bitcoin as it has proven to be 100% reliable and a way for anyone based in the US to be able to fund their gambling site accounts quickly and without any fuss of hassle.
Much like any other currency you can use the value of Bitcoin does fluctuate, and that is one of the other benefits you can have of using Bitcoin as the value can increase against you own home currency and as such any winnings you achieve and have sent to your Bitcoin Wallet may increase in value based on the current exchange rate, however the opposite is also true.
