The digital currency that is currently wide spread on the Online service is Bitcoins which is also known as cryptocurrency. This digital currency was first proposed in the year of 2008. Since then it has been growing in its popularity. This was started initially as a free source project on Source Forge. This system does not have any central body which governs the transactions and exchange rates. It is done through key cryptography system. Though there is a general talk about the volatile exchange rates and high risk losses, the currencies have sustained well in the market and are continuing to grow exponentially. The Bitcoins are secured, protected and stored using digital wallet services known as the Bitcoin Wallets.

Though there are certain constraints involved in using these wallets, they are the primary heart of using a Bitcoin. These wallets must be protected from hijacks and other viruses otherwise there is every possibility of loss or theft of the Bitcoins from the users. Alternate currency systems were proposed and even electronic form of currency was suggested, but nothing gained popularity the way Bitcoins did. The Bitcoin is an international currency so there is no need of bank fees for international transactions. The Bitcoin Wallets can be taken into offline storage media and protected with passwords and other means of authentication in order to avoid unnecessary leakage or loss of the data. The alternate currency system is gaining momentum in the market mainly because of the bitcoin games as the major reason being it has no boundaries and the level of anonymity is maintained. These factors are leading to its growth in spite of the security issues which can be fixed and overcome leading to an enormous success for Bitcoins!
