Bitcoin, also known as BTC, is a decentralized digital currency that was invented by an unknown person or group of people under the name Satoshi Nakamoto. It is, by far, the most widely known and used cryptocurrency in the world.

As a digital currency, Bitcoin is not controlled by any central authority, such as a government or financial institution. Instead, it relies on a distributed network of computers that record and verify transactions through a technology called blockchain.

One of the key features of Bitcoin is its limited supply, with a maximum of 21 million bitcoins that will ever be created. This scarcity has helped fuel its value over time, with Bitcoin becoming increasingly recognized as a store of value like gold.
