Bitcoins have several advantages. First of all it's fast. Operations in bitcoins are much faster than any interbank transfers. It`s also cheap. Transactions in bitcoins do not usually include commissions and if they do, commissions are minimal. There is no inflation. Bitcoin is designed the way so that the number of coins is limited. It was originally conceived that it is impossible to "get" more than 21 million coins. This means that once this number is reached, it will be impossible to create more bitcoins, so inflation is impossible here. And the last but not the least, bitcoin belongs only to you. You own a private key and the corresponding public key, which is the address of the bitcoin-wallet. Nobody can take the money, except for yourself.
