Bitcoin Cash (BCH) emerged in 2017 as a hard fork of Bitcoin, designed to address scalability challenges faced by its predecessor. By increasing the block size from 1 MB to 8 MB (and later up to 32 MB), Bitcoin Cash enables faster transaction processing and lower fees, making it more suitable for everyday digital payments. This upgrade attracted significant attention from crypto enthusiasts and developers alike, helping BCH secure a consistent position among the top 20 cryptocurrencies by market capitalization.
Despite its divergence from Bitcoin, Bitcoin Cash retains several core characteristics. Like BTC, it operates on a deflationary model with a maximum supply capped at 21 million coins. It also maintains the same 10-minute block production time and relies on the SHA-256 cryptographic hashing algorithm for mining. These shared foundations ensure network security and decentralization while allowing for improved performance through larger block sizes.
Key Features of Bitcoin Cash and How It Works
At its core, Bitcoin Cash functions similarly to Bitcoin but with critical technical enhancements. Both networks use a Proof-of-Work (PoW) consensus mechanism, where miners validate transactions and secure the blockchain by solving complex mathematical problems. In return, they are rewarded with newly minted BCH tokens and transaction fees.
One of the most significant advantages of Bitcoin Cash is its ability to process more transactions per second due to its expanded block size. While Bitcoin struggles with congestion during peak usage—leading to high fees and slow confirmations—BCH offers a more scalable solution. This makes it particularly appealing for microtransactions and point-of-sale payments in real-world applications.

Unlike Bitcoin, Bitcoin Cash does not implement Segregated Witness (SegWit), a protocol upgrade that separates signature data from transaction data to increase effective block capacity. Instead, BCH takes a more direct approach: increasing the actual block size limit. This design choice reflects the project’s philosophy of on-chain scaling rather than relying on second-layer solutions.
Additionally, Bitcoin Cash supports smart contract functionality through various development frameworks, setting it apart from Bitcoin’s more limited scripting capabilities. This opens doors for decentralized applications (dApps) and programmable money use cases on the BCH network, although adoption in this area remains less widespread compared to platforms like Ethereum or OKX Chain.
Mining Bitcoin Cash: Methods and Profitability
Bitcoin Cash uses the Proof-of-Work consensus model, meaning miners play a crucial role in validating transactions and maintaining network integrity. New blocks are added approximately every 10 minutes, and miners receive BCH rewards plus transaction fees for their efforts.
The mining reward undergoes halving approximately every four years—or after every 210,000 blocks mined—ensuring a controlled issuance schedule aligned with Bitcoin’s monetary policy. As of now, the block reward stands at 6.25 BCH per block, following the most recent halving event.
There are three primary ways to mine Bitcoin Cash:
- Solo Mining: Individuals can mine independently using their own hardware. However, due to the high computational power required and intense competition, solo mining is rarely profitable without access to advanced ASIC (Application-Specific Integrated Circuit) machines and low-cost electricity.
- Mining Pools: Joining a mining pool allows participants to combine their computing power and increase the likelihood of successfully mining a block. Rewards are distributed proportionally based on each miner’s contributed hash rate. While individual payouts are smaller, they occur more frequently, offering greater consistency.
- Cloud Mining: This method involves renting computing power from third-party providers via contracts. It eliminates the need for purchasing and maintaining physical hardware but comes with risks such as potential scams or unprofitable returns if market conditions shift.
To maximize efficiency, miners should use software optimized for SHA-256 algorithms and pair it with high-performance ASIC rigs specifically designed for Bitcoin-based networks.

Frequently Asked Questions (FAQ)
Q: What is the main difference between Bitcoin and Bitcoin Cash?
A: The primary difference lies in block size. Bitcoin Cash increased the block size to 32 MB (from Bitcoin’s 1 MB), enabling faster and cheaper transactions. This change was made to improve scalability and support everyday use as digital cash.
Q: Is Bitcoin Cash a good investment?
A: Investment potential depends on individual goals and market outlook. While BCH has strong fundamentals and a dedicated community, it faces stiff competition from other layer-1 blockchains. Investors should consider its historical performance, adoption trends, and long-term utility before investing.
Q: Can Bitcoin Cash be used for smart contracts?
A: Yes, Bitcoin Cash supports smart contracts through scripting enhancements and development tools like CashScript. However, its ecosystem is less mature than platforms such as Ethereum or OKX Chain.
Q: Does Bitcoin Cash use the same mining algorithm as Bitcoin?
A: Yes, both networks use the SHA-256 hashing algorithm, meaning miners can technically switch between BTC and BCH depending on profitability.
Q: Why did Bitcoin Cash fork from Bitcoin?
A: The fork occurred due to disagreements within the Bitcoin community about how to scale the network. One group favored increasing block size (leading to BCH), while the other supported SegWit and off-chain scaling like the Lightning Network.
Q: How many Bitcoin Cash coins are left to be mined?
A: With a maximum supply of 21 million and a current circulating supply of 19.89 million, approximately 1.11 million BCH remain to be mined over the coming decades.
Final Thoughts on Bitcoin Cash in 2025
Bitcoin Cash continues to serve as a compelling alternative to Bitcoin for users prioritizing fast, low-cost transactions. While it hasn’t achieved the same level of mainstream adoption as some newer blockchains, its robust security model, fixed supply, and active development community provide a solid foundation for future growth.
Whether you're interested in using BCH for payments, investing in its long-term value, or exploring its technical capabilities, understanding its role in the broader crypto landscape is essential.
