It's organized through a network known as a blockchain, which is basically an online ledger that keeps a secure record of each transaction and bitcoin price all in one place.

Every time anyone buys or sells bitcoin, the swap gets logged. Several hundred of these back-and-forths make up a block.

No one controls these blocks, because blockchains are decentralized across every computer that has a bitcoin wallet, which you only get if you buy bitcoins.

True to its origins as an open, decentralized currency, bitcoin is meant to be a quicker, cheaper, and more reliable form of payment than money tied to individual countries.

But even for those who don't discover using their own high-powered computers, anyone can buy and sell bitcoins at the bitcoin price they want, typically through online exchanges like Coinbase or LocalBitcoins.

Satoshi Nakamoto, bitcoin's enigmatic founder, arrived at that number by assuming people would discover, or "mine," a set number of blocks of transactions daily.

Every four years, the number of bitcoins released relative to the previous cycle gets cut in half, as does the reward to miners for discovering new blocks.

The reward right now is As a result, the number of bitcoins in circulation will approach 21 million, but never hit it. Bitcoin - Dollar im Vergleich.
