$BTC

Bitcoin (BTC) is a decentralized cryptocurrency based on a blockchain network. Its structure consists of blocks, where each block contains a set of verified transactions. Each block is linked to the previous one through a cryptographic hash, forming a continuous and immutable chain. Distributed nodes validate and store the complete chain, ensuring transparency and security. Mining, through proof of work (Proof of Work), allows new blocks to be added to the network, incentivizing participants with rewards in BTC. Additionally, Bitcoin uses public and private keys to control the ownership and transfer of coins securely and anonymously.
