$BTC Bitcoin (BTC) is a type of cryptocurrency, which is a digital or virtual form of currency that uses cryptography for security. It's decentralized, meaning it operates without a central authority like a government or financial institution. Bitcoin transactions happen directly between users over a peer-to-peer network and are recorded on a public ledger called the *blockchain*.

Here are some key things to know about Bitcoin:

1. *Decentralized Nature*:

- Bitcoin operates without a central bank or intermediary.

- It is maintained by a network of computers (called miners) that validate and secure transactions.

2. *Blockchain Technology*:

- Every Bitcoin transaction is verified and recorded on the blockchain, which is a transparent, immutable, and distributed ledger.

- The blockchain prevents double-spending and ensures that every transaction is authentic.

3. *Mining*:

- New Bitcoins are generated through a process called mining, where miners solve complex mathematical problems to validate transactions and add them to the blockchain.

- Miners are rewarded with new Bitcoins for their work, which makes mining an essential part of the Bitcoin network.

4. *Limited Supply*:
