Bitcoin is a computerized money which works liberated from any focal control or the oversight of banks or legislatures. Rather it depends on distributed programming and cryptography.
A public record records all bitcoin exchanges and duplicates are hung on servers all over the planet. Anybody with an extra PC can set up one of these servers, known as a hub. Agreement on who claims which coins is arrived at cryptographically across these hubs instead of depending on a focal wellspring of trust like a bank.
Each exchange is freely communicated to the organization and shared from one hub to another. Like clockwork or so these exchanges are gathered together by diggers into a gathering called a block and added forever to the blockchain. This is the conclusive record book of bitcoin.
Similarly you would keep conventional coins in an actual wallet, virtual monetary forms are held in computerized wallets and can be gotten to from client programming or a scope of on the web and equipment devices.
Bitcoins can as of now be partitioned by seven decimal places: a thousandth of a bitcoin is known as a milli and 100 millionth of a bitcoin is known as a satoshi.
In truth there is no such thing as a bitcoin or a wallet, only understanding among the organization about responsibility for coin. A confidential key is utilized to demonstrate responsibility for to the organization while making an exchange. An individual could just retain their confidential key and need nothing else to recover or spend their virtual money, an idea which is known as a "mind wallet".
