Bitcoin Cash (BCH) is a decentralized digital currency that emerged as a solution to some of the scalability challenges faced by Bitcoin (BTC). Designed to function as peer-to-peer electronic cash, BCH enables fast, low-cost transactions without relying on traditional financial intermediaries. Born from a hard fork of the Bitcoin blockchain in August 2017, Bitcoin Cash has since evolved into a distinct cryptocurrency with its own development path, community, and use cases.
In this comprehensive guide, we’ll explore the origins, technical mechanics, tokenomics, and real-world applications of Bitcoin Cash—helping you understand why it remains a notable player in the evolving cryptocurrency landscape.
The Origins of Bitcoin Cash
The creation of Bitcoin Cash was driven by a fundamental disagreement within the Bitcoin community about how to scale the network effectively. As Bitcoin gained popularity, transaction congestion increased, leading to slower processing times and higher fees. To address this, two primary solutions emerged:
- Increasing block size: Allow more transactions per block by raising the 1MB limit.
- Off-chain scaling: Implement second-layer solutions like the Lightning Network to process transactions outside the main chain.
Supporters of larger blocks believed that on-chain scalability was essential for Bitcoin to fulfill its original purpose as a digital cash system. When consensus couldn’t be reached, a faction of developers, miners, and investors initiated a hard fork on August 1, 2017, resulting in the birth of Bitcoin Cash (BCH).
A hard fork occurs when a blockchain splits into two separate chains due to incompatible protocol changes. Nodes running the new rules can no longer communicate with those on the old chain, creating two independent networks—each with its own transaction history and native currency.

Bitcoin vs. Bitcoin Cash: Key Differences
While both BTC and BCH share the same early blockchain history, they have diverged significantly in design and philosophy.
Block Size and Transaction Speed
- Bitcoin (BTC): Maintains a 1MB block size (increased via SegWit to ~4MB effectively), limiting transaction throughput.
- Bitcoin Cash (BCH): Features an 8MB base block size, expandable up to 32MB, allowing for significantly more transactions per block.
This larger capacity means BCH can process transactions faster and with fewer delays during peak usage periods.
Transaction Fees
Due to lower congestion, Bitcoin Cash typically offers lower transaction fees than Bitcoin. While BTC fees can spike during high demand—sometimes exceeding $10–$20—BCH fees often remain below $0.01, making it more practical for everyday payments.
Use Case and Vision
- Bitcoin (BTC): Widely viewed as “digital gold”—a store of value and long-term investment.
- Bitcoin Cash (BCH): Positioned as “peer-to-peer electronic cash,” optimized for daily spending and micropayments.
This philosophical split defines their respective development roadmaps: BTC focuses on security and scarcity, while BCH prioritizes usability and accessibility.
How Does Bitcoin Cash Work?
Like Bitcoin, Bitcoin Cash operates on a Proof-of-Work (PoW) consensus mechanism. This ensures network security through decentralized mining, where participants compete to validate transactions and add new blocks to the blockchain.
Mining Process
Miners use powerful computing hardware to solve complex cryptographic puzzles. The first miner to find a valid solution broadcasts it to the network for verification. Once confirmed:
- A new block is added to the BCH blockchain.
- The winning miner receives a block reward in newly minted BCH.
- Transaction fees from included transactions are also collected.
This process maintains decentralization, prevents double-spending, and secures the network without relying on a central authority.
All nodes in the network maintain a full copy of the blockchain, ensuring transparency and consistency across the system.
BCH Tokenomics: Supply, Halving, and Scarcity
Bitcoin Cash mirrors Bitcoin’s deflationary economic model, designed to preserve value over time.
Fixed Supply
- Maximum supply: 21 million BCH
- Circulating supply (as of 2025): Approximately 19.5 million
This capped supply creates artificial scarcity, similar to precious metals like gold, supporting long-term value retention.
Halving Events
Every 210,000 blocks (roughly every four years), the block reward is cut in half—a process known as halving. This slows down new coin issuance and reduces inflationary pressure.
| Halving Stage | Block Reward |
|---|---|
| Genesis | 50 BCH |
| After 1st | 25 BCH |
| After 2nd | 12.5 BCH |
| Current (3rd) | 6.25 BCH |
The next halving is expected around 2028, reducing the reward to 3.125 BCH per block.
As of 2025, BCH’s market capitalization sits around $4.5 billion, with an all-time high price of **$3,909** reached in August 2021.

Who Created Bitcoin Cash?
Bitcoin Cash was not the work of a single individual but rather a collective effort led by key figures in the crypto space:
- Haipo Yang: CEO of ViaBTC and lead developer behind the BCH fork. A respected figure in the mining and exchange communities.
- Roger Ver: Early Bitcoin investor and vocal advocate for BCH, often referred to as “Bitcoin Jesus” for his promotional efforts.
- Jihan Wu: Co-founder of Bitmain, one of the largest manufacturers of ASIC mining equipment.
These individuals championed larger block sizes as essential for true financial freedom and mass adoption. Their vision attracted support from miners, developers, exchanges, and users who shared concerns about Bitcoin’s growing centralization and fee structure.
It’s important to note that while these leaders provided direction, the success of BCH relied heavily on community consensus and decentralized participation.
Frequently Asked Questions (FAQ)
Q: Is Bitcoin Cash the same as Bitcoin?
A: No. While they share a common origin, Bitcoin Cash branched off via a hard fork in 2017 with larger blocks and lower fees, aiming to be used more like cash.
Q: Can I spend Bitcoin Cash in real stores?
A: Yes. Several merchants and online platforms accept BCH for goods and services, especially in regions embracing cryptocurrency payments.
Q: Is Bitcoin Cash secure?
A: Yes. It uses the same proven Proof-of-Work mechanism as Bitcoin and benefits from a robust mining network.
Q: What happens after all 21 million BCH are mined?
A: Miners will rely solely on transaction fees for rewards, similar to Bitcoin’s future model. The network is designed to remain secure even after block rewards end.
Q: Why did the Bitcoin Cash fork happen?
A: It resulted from disagreements over scalability—specifically whether to increase block size or rely on off-chain solutions like the Lightning Network.
Q: Is Bitcoin Cash a good investment?
A: Like all cryptocurrencies, it carries risk due to price volatility. However, its fixed supply and utility as digital cash may appeal to long-term investors.
Why Bitcoin Cash Still Matters in 2025
Despite facing competition from newer blockchains and stablecoins, Bitcoin Cash maintains relevance due to its core strengths:
- Low-cost global transfers
- Fast confirmation times
- Decentralized payment infrastructure
- Strong ideological foundation in financial sovereignty
For users seeking an alternative to traditional banking systems or high-fee networks, BCH offers a functional, battle-tested option rooted in Satoshi Nakamoto’s original whitepaper vision.
