Bitcoin can be considered simply as the adaptation of the traditional monetary system to the digital world. While BTC in the account can be converted into different currencies through ATMs located in the USA, Turkey and different European countries, shopping can be done from shops using Bitcoin payment system.
Another similarity between real currencies and BTC is the need for wallets to store. Bitcoins stored in these wallets, called virtual wallets, are kept safe in wallets protected against theft by encryption. It is enough to protect the password created to prevent it from being stolen.
For BTC transfer, the address information of the wallets is used. Bitcoin transfer is made after signing with asymmetric encryption in transfer transactions made over wallet addresses. The transfer is announced on each network and is included in the blockchain to prevent the use of more than one BTC at the same time.
