Bitcoin Cash (BCH) remains one of the most talked-about digital assets in the cryptocurrency ecosystem. Designed as a peer-to-peer electronic cash system, BCH aims to deliver fast transactions, low fees, and scalable blockchain infrastructure — all critical components for everyday use as digital money. As interest in decentralized payment solutions grows, understanding Bitcoin Cash’s technology, market position, and real-world utility becomes increasingly valuable.
This guide dives deep into everything you need to know about Bitcoin Cash in 2025 — from its origins and technical framework to how it compares with Bitcoin and where to securely engage with the network.
What Is Bitcoin Cash (BCH)?
Bitcoin Cash (BCH) is a decentralized, permissionless cryptocurrency that operates on a public blockchain. It was created to fulfill the original vision of Bitcoin as described in Satoshi Nakamoto’s whitepaper: a digital cash system enabling fast, low-cost global payments without intermediaries.
Unlike traditional financial systems that rely on banks or payment processors, Bitcoin Cash allows users to send and receive value directly, with transactions verified by a distributed network of miners. One of its defining features is an increased block size limit — currently set at 32MB — allowing more transactions per block and significantly reducing congestion and fees.

The Origins of Bitcoin Cash: A Response to Scaling Challenges
Bitcoin Cash emerged in August 2017 as a result of a hard fork from the original Bitcoin blockchain. The split occurred due to growing disagreements within the Bitcoin community over how to scale the network to handle increasing transaction volume.
At the heart of the debate were two competing visions:
- Small block proponents believed that keeping blocks small (1MB at the time) preserved decentralization by making it easier for individual users to run full nodes.
- Large block advocates argued that increasing block size was essential to keep transaction fees low and maintain Bitcoin’s usability as a payment method.
When Bitcoin implemented Segregated Witness (SegWit) — a solution that increased capacity by changing how data is stored — a faction of developers and miners rejected the change. They believed it was too complex and compromised on-chain scalability. Instead, they pushed for a simpler fix: larger blocks.
Thus, Bitcoin Cash was born through a hard fork, creating a new blockchain with upgraded block size limits while maintaining compatibility with Bitcoin’s early design principles.
How Does Bitcoin Cash Work?
Like Bitcoin, Bitcoin Cash uses Proof-of-Work (PoW) consensus to secure its network. Miners compete to solve cryptographic puzzles and validate transactions, earning newly minted BCH coins and transaction fees as rewards.
Key technical features include:
- 32MB block size: Enables thousands of transactions per second under optimal conditions.
- Adjustable mining difficulty: The difficulty retargets after each block (DAA algorithm), helping maintain consistent block times even during hash rate fluctuations.
- No SegWit: Transaction data remains fully on-chain, preserving simplicity and transparency.
- Replay protection: Prevents transactions on one chain from being duplicated on the other after forks.
These upgrades make Bitcoin Cash particularly suitable for micropayments and high-frequency transactions — use cases where traditional cryptocurrencies often struggle due to high fees or slow confirmations.
How Is Bitcoin Cash Different From Bitcoin?
While both share common roots, several key differences set Bitcoin Cash apart:
| Feature | Bitcoin (BTC) | Bitcoin Cash (BCH) |
|---|---|---|
| Block Size | 1MB (with SegWit up to ~4MB) | Up to 32MB |
| Primary Use Case | Digital gold / Store of value | Peer-to-peer electronic cash |
| Transaction Fees | Often higher during peak usage | Consistently low |
| Scaling Approach | Off-chain (e.g., Lightning Network) | On-chain scaling |
| Philosophy | Security and decentralization first | Usability and accessibility first |
Bitcoin Cash prioritizes usability for daily transactions, while Bitcoin has increasingly positioned itself as a long-term store of value.

How Many Bitcoin Cash Coins Are in Circulation?
Bitcoin Cash has a maximum supply cap of 21 million coins, matching Bitcoin’s scarcity model. This fixed supply ensures resistance to inflation and supports long-term value retention.
As of 2025, over 19.7 million BCH are already in circulation, with new coins issued approximately every 10 minutes through mining rewards. The block reward undergoes halving roughly every four years; the most recent occurred in 2024, reducing miner rewards from 6.25 to 3.125 BCH per block.
This predictable issuance schedule reinforces investor confidence and aligns with sound monetary principles.
How Is Bitcoin Cash Secured?
Security in the Bitcoin Cash network relies on the same robust Proof-of-Work mechanism used by Bitcoin. The computational power required to attack the network makes malicious activity economically unfeasible for most actors.
Additional safeguards include:
- Decentralized mining pool distribution
- Frequent difficulty adjustments to prevent chain stagnation
- Open-source codebase subject to continuous community review
Despite being smaller than Bitcoin in terms of market capitalization, Bitcoin Cash maintains a strong hashrate, often shared with other PoW chains through merged mining — further enhancing its resilience.
How Do You Mine Bitcoin Cash?
Mining Bitcoin Cash involves using specialized hardware (ASICs) to perform calculations that verify transactions and add them to the blockchain. Miners who successfully create a new block are rewarded with newly minted BCH and transaction fees.
Steps to start mining:
- Acquire ASIC mining equipment compatible with SHA-256 algorithm
- Join a mining pool or mine solo
- Install mining software (e.g., CGMiner, BFGMiner)
- Configure wallet address for payouts
- Begin mining operations
Profitability depends on electricity costs, hardware efficiency, and current BCH price. Many miners also participate in merged mining, where they simultaneously secure multiple blockchains (like BCH and BTC) without extra computational cost.
Where Can You Buy Bitcoin Cash?
Bitcoin Cash is widely available on major cryptocurrency exchanges around the world. Users can purchase BCH using fiat currencies (USD, EUR, etc.) or trade it against other cryptocurrencies like BTC or ETH.
Popular platforms offering BCH trading include:
- Global exchanges with high liquidity
- Mobile apps supporting self-custody wallets
- Peer-to-peer marketplaces for direct transactions
After purchasing, it's recommended to store BCH in a secure wallet — either hardware-based or software-based with strong encryption.

Frequently Asked Questions (FAQ)
What is the main purpose of Bitcoin Cash?
Bitcoin Cash aims to serve as fast, affordable digital cash for everyday transactions. It focuses on on-chain scalability to ensure low fees and quick confirmations, making it practical for real-world spending.
Is Bitcoin Cash a fork of Bitcoin?
Yes, Bitcoin Cash originated from a hard fork of the Bitcoin blockchain in August 2017. This split created two separate cryptocurrencies: Bitcoin (BTC) and Bitcoin Cash (BCH), each with its own network and development path.
Can I use Bitcoin Cash for payments?
Absolutely. Numerous merchants and online services accept BCH for goods and services. Its low transaction fees and fast processing times make it ideal for both domestic and cross-border payments.
