Bitcoin isn't attached to a state or government, so itu doesn't have a central issuing authority or regulatory body, bassically, that means there's no organizational deciding when to make more bitcoins, digiring out how many to produce, kering track of where they are, so how does bitcoin work as a currency ?
Firat of all there is no way that anyone can make bitcoins. And there are only 21 million bitcoins in the world. Bitcoin is a platform in the blockchain. Blockchain is like the OS of your pc and Bitcoin is the application. And just like our money, bitcoin has no physical body its all about the "trust" you put into it. Real world money is just a piece of paper, again its all about the "trust".
