Bitcoin is similar, although it is significantly more traceable and expensive than cash. Traceability can be critical to certain transactions. If someone wants to buy illegal goods like illicit drugs, cash is ideal because it does not produce a record of the transaction that can easily by traced or associated with the payor or payee.
Bitcoins have value because they are useful and because they are scarce. As they are accepted by more merchants, their value will stabilize. See the list of Bitcoin-accepting sites. When we say that a currency is backed up by gold, we mean that there's a promise in place that you can exchange the currency for gold.
