Bitcoin Gold (BTG) is a cryptocurrency designed to be decentralized and accessible to a broader range of users. It was created as a hard fork of the Bitcoin blockchain in 2017, aiming to address issues related to mining centralization and the dominance of Application-Specific Integrated Circuits (ASICs) in the mining process.

Bitcoin Gold uses the Equihash-BTG proof-of-work algorithm, which allows for mining using common graphics processing units (GPUs) rather than specialized ASICs. This approach is intended to democratize and decentralize the mining process, making it more accessible to individuals and smaller operations.

To use Bitcoin Gold, users need a secure wallet to store the tokens. They can then access cryptocurrency exchanges like Binance, Coinbase, or Kraken to buy and sell BTG. The transactions are recorded on the Bitcoin Gold blockchain, which operates on a peer-to-peer network without a central authority.

Despite its goals, Bitcoin Gold has faced challenges, including 51% hashing attacks and delisting from some exchanges due to security concerns and disputes over damages. The cryptocurrency's market performance has also been volatile, with significant price fluctuations over time.

The development roadmap for Bitcoin Gold includes a focus on interoperability, applications, infrastructure, and the lightning network. The project aims to shift from a board-based governance structure to a decentralized autonomous organization (DAO) model, with ongoing updates to its core technology and tools.
