Bitcoin transaction is very fast and completely transparent. Every transaction is protected with digital sign of the payer. This private key prevents unauthorised access to the transaction. Loss of bitcoins by means of loss of the private key cannot be recovered. Bitcoin transactions are stored in public ledgers so they can be viewed by anyone. However the owner of the account is not revealed until anyone provides information online. Prime responsibility of account holder is to protect the privacy. Bitcoin is a new currency that is developed recently and it is a new approach that has not been attempted in the past.
