Bitcoin (BTC), is the first and most well-known cryptocurrency. It operates on a decentralised network using blockchain technology to enable peer-to-peer transactions without intermediaries. Bitcoin is often referred to as digital gold due to its limited supply—capped at 21 million coins—and its role as a store of value.

Transactions on the Bitcoin network are verified through a proof-of-work (PoW) consensus mechanism, which involves miners solving complex mathematical problems to add new blocks to the blockchain. This process ensures security and integrity while controlling the issuance of new bitcoins.

Bitcoin's primary use case is as a digital currency for transferring value, but it also serves as an investment asset and a hedge against inflation. With widespread acceptance and growing institutional interest.
