Bitcoin Cash (BCH) is one of the most notable hard forks in the history of blockchain technology. Emerging from a fundamental disagreement within the Bitcoin community, BCH was created to restore Bitcoin’s original vision as a peer-to-peer electronic cash system. Unlike alternative scaling solutions, Bitcoin Cash pursued on-chain scaling through larger block sizes, setting it apart from Bitcoin (BTC) in both philosophy and technical design.
This article explores the complete development journey of Bitcoin Cash — from its ideological roots and contentious fork to its technological upgrades and market presence today.
The Origins of Bitcoin Cash: A Response to Bitcoin’s Scaling Crisis
The story of Bitcoin Cash begins with the limitations of the original Bitcoin network. In 2008, Satoshi Nakamoto released the Bitcoin whitepaper titled “Bitcoin: A Peer-to-Peer Electronic Cash System,” envisioning a decentralized digital currency for everyday transactions. Initially, Bitcoin blocks had no strict size limit and could theoretically reach up to 32MB, but this posed risks such as network spam and denial-of-service (DDoS) attacks.
To ensure stability, Satoshi implemented a 1MB block size cap. While effective at maintaining security in the early days, this restriction became problematic as user adoption surged. By 2015–2017, the network regularly faced congestion, leading to high transaction fees and slow confirmation times — undermining Bitcoin’s utility as a payment method.

Two competing visions emerged within the community:
- Small-block proponents (led by Bitcoin Core developers) favored off-chain scaling via Segregated Witness (SegWit) and the Lightning Network.
- Large-block advocates argued that true scalability required increasing block size directly on the blockchain.
This ideological rift culminated in a hard fork on August 1, 2017, giving birth to Bitcoin Cash (BCH).
The Hard Fork: Birth of a New Cryptocurrency
On August 1, 2017, at block height 478,558, miners supporting larger blocks initiated a hard fork from the Bitcoin blockchain. Every holder of BTC at the time received an equal amount of BCH on a 1:1 basis, totaling a maximum supply of 21 million BCH.
The newly formed Bitcoin Cash chain introduced several key changes:
- Removal of Segregated Witness (SegWit)
- Block size increased from 1MB to 8MB
- Later upgraded to support 32MB blocks
These modifications allowed for significantly higher transaction throughput and lower fees, reinforcing BCH’s role as a medium of exchange rather than just a store of value.
Notably, the cryptocurrency was initially labeled BCC — a naming choice that caused confusion due to an existing token using the same ticker. The community quickly adopted BCH as the standard symbol.
Major Milestones in Bitcoin Cash Development
2017: Launch and Immediate Adoption
Following the fork, major exchanges like OKX, Bitfinex, and Kraken listed BCH within days. Miners migrated hash power to secure the new chain, ensuring network stability.
2018: The New York Agreement Fallout
The SegWit2x proposal — which aimed to implement SegWit and later increase block size — was canceled amid controversy. This failure reinforced support for BCH among those who believed on-chain scaling was essential.
2019–2020: Protocol Upgrades and Tokenization
Bitcoin Cash implemented several upgrades:
- May 2019 Fork: Enabled Schnorr signatures and improved smart contract functionality.
- November 2020 Upgrade: Introduced Unlimited Scaling Protocol (USP) enhancements and better replay protection.
Developers also began exploring token creation standards like Simple Ledger Protocol (SLP), allowing users to issue custom tokens on the BCH chain.
2021–2025: Merchant Adoption and Global Use Cases
Despite market volatility, Bitcoin Cash gained traction in countries with limited banking infrastructure. Real-world use cases include:
- Cross-border remittances in Africa and Southeast Asia
- Micropayments for digital content
- Point-of-sale transactions via mobile wallets
How Bitcoin Cash Differs from Bitcoin
| Feature | Bitcoin (BTC) | Bitcoin Cash (BCH) |
|---|---|---|
| Block Size | 1MB (effective with SegWit ~4MB) | Up to 32MB |
| Transaction Speed | Slower during peak times | Faster due to larger blocks |
| Fees | Higher during congestion | Consistently low |
| Primary Use Case | Digital gold / Store of value | Peer-to-peer electronic cash |
While BTC has evolved into a digital reserve asset, BCH remains committed to Nakamoto’s original vision: fast, cheap, and reliable transactions for daily use.
Market Performance and Current Status (as of 2025)
As of 2025, Bitcoin Cash maintains a strong position in the cryptocurrency market:
- Price: $481.26
- 24-Hour Trading Volume: $225.25 million
- Market Cap: $9.57 billion
- Ranking: #9 on major crypto tracking platforms
- Circulating Supply: 19.89 million BCH
- Max Supply: 21 million BCH
These figures reflect sustained investor interest and ongoing utility in real-world applications.

Frequently Asked Questions (FAQs)
Q: What is Bitcoin Cash?
A: Bitcoin Cash (BCH) is a cryptocurrency created in 2017 through a hard fork of the Bitcoin blockchain. It aims to serve as peer-to-peer electronic cash by supporting larger block sizes for faster and cheaper transactions.
Q: Is Bitcoin Cash a scam or legitimate project?
A: Bitcoin Cash is a legitimate cryptocurrency with active development, mining support, and exchange listings. It emerged from genuine philosophical differences within the Bitcoin community regarding scalability.
Q: Can I use Bitcoin Cash for payments?
A: Yes. Many merchants worldwide accept BCH for goods and services, especially in regions with underdeveloped financial systems. Wallets like Electron Cash and Badger Wallet facilitate easy spending.
Q: Why did Bitcoin Cash split from Bitcoin?
A: The split occurred because some developers and miners believed that increasing block size was the best way to scale Bitcoin. Others supported off-chain solutions like SegWit and Lightning Network, leading to irreconcilable differences.
Q: Will Bitcoin Cash ever surpass Bitcoin in value?
A: While possible in theory, BTC currently holds dominant market position, brand recognition, and institutional adoption. BCH focuses more on usability than competing directly on price.
Q: How is the security of Bitcoin Cash ensured?
A: Like Bitcoin, BCH uses Proof-of-Work (PoW) consensus. Miners validate transactions and secure the network using computational power. Though it has less hash rate than BTC, it remains robust against attacks.
The Future of Bitcoin Cash
Looking ahead, the future of Bitcoin Cash hinges on three factors:
- Merchant Adoption: Expanding point-of-sale usage globally.
- Developer Innovation: Enhancing smart contract capabilities and token standards.
- User Education: Clarifying its role versus BTC and other cryptocurrencies.
With continued focus on low-cost transactions and financial inclusion, BCH remains relevant in the evolving digital economy.
