When it comes to cryptocurrencies, few debates have sparked as much discussion as the one between Bitcoin (BTC) and Bitcoin Cash (BCH). Both digital assets share a common origin, but their paths diverged in a historic moment on 1 August 2017, when Bitcoin Cash emerged as a hard fork of the original Bitcoin blockchain. This split wasn’t just technical—it represented a philosophical divide over how cryptocurrency should evolve. In this article, we’ll explore the key differences between Bitcoin and Bitcoin Cash, from block size and scalability to price performance and future potential.
Origins and Launch Dates
Bitcoin holds a unique position in the digital asset world—it’s the original cryptocurrency, launched on 3 January 2009 by the pseudonymous Satoshi Nakamoto. As the first decentralized digital currency, Bitcoin introduced blockchain technology to the world and laid the foundation for thousands of alternative cryptocurrencies.
Bitcoin Cash, on the other hand, entered the scene nearly eight years later on 1 August 2017. It was created not as a new invention, but as a response to growing dissatisfaction with Bitcoin’s ability to scale. While Bitcoin had become globally recognized, its network began struggling with slow transaction speeds and high fees during periods of high demand.

This timing difference is crucial: Bitcoin had already built a massive user base, brand recognition, and institutional trust by the time BCH arrived. Bitcoin Cash, despite its technical improvements, started at a disadvantage in terms of market perception and adoption.
The Core Dispute: Block Size and Scalability
The most significant technical difference between Bitcoin and Bitcoin Cash lies in block size, which directly impacts transaction speed and network scalability.
Bitcoin’s Approach: SegWit and the Lightning Network
Bitcoin maintains a block size limit of 1 MB (effectively increased through Segregated Witness, or SegWit). This constraint allows Bitcoin to process roughly 7 transactions per second (TPS)—a number that pales in comparison to traditional payment systems like Visa, which handles thousands of transactions per second.
To address this limitation, the Bitcoin community adopted two primary solutions:
- SegWit: A soft fork that separates signature data from transaction data, increasing block capacity without changing the size limit.
- Lightning Network: A second-layer protocol that enables off-chain transactions through payment channels. These microtransactions are settled later on the main blockchain, reducing congestion.
While these solutions have improved efficiency, critics argue they add complexity and shift transaction processing away from the base layer.
Bitcoin Cash’s Solution: Bigger Blocks
Bitcoin Cash took a simpler, more direct approach: increase the block size. Initially launched with an 8 MB block size, BCH quickly upgraded to 16 MB by late 2017 and then to 32 MB in 2018. This allows the network to handle significantly more transactions per block—potentially up to 100 TPS under optimal conditions.
The philosophy behind BCH is clear: keep transactions fast and cheap by scaling on-chain. Proponents believe this aligns better with Satoshi Nakamoto’s original vision of peer-to-peer electronic cash.
Price Performance: Market Value and Volatility
Despite its technical advantages, Bitcoin Cash has never matched Bitcoin in market value. The price gap reflects not just technological differences but also investor sentiment, brand strength, and network effects.
| Year | Bitcoin (BTC) | Bitcoin Cash (BCH) |
|---|---|---|
| 2017 | $12,952 | $2,557 |
| 2018 | $3,865 | $160 |
| 2019 | $7,285 | $152 |
Closing prices at year-end for BTC and BCH.
As of recent data, Bitcoin trades around $9,000–$11,000, while Bitcoin Cash hovers between $350–$400. During the 2017 bull run, BTC peaked near $20,000**, while BCH reached an all-time high of about **$4,000—impressive for a new asset, but still far behind BTC.
The reason? Bitcoin is “digital gold.” It’s seen as a store of value, a hedge against inflation, and a benchmark for the entire crypto market. Bitcoin Cash, while functional as digital cash, lacks the same level of institutional backing and global recognition.
Smart Contracts and Ecosystem Development
Initially, neither Bitcoin nor Bitcoin Cash was built for complex smart contracts like those on Ethereum. However, both networks have evolved to support limited programmable functions.
Bitcoin Smart Contract Features:
- Multi-signature wallets: Require multiple private keys to authorize a transaction.
- Escrow services: A third party holds funds until conditions are met.
- Time-locked transactions: Funds are released only after a specific date.
- Testamentary scripts: Automatically transfer funds to heirs if the wallet remains inactive.
Bitcoin Cash Enhancements:
Bitcoin Cash goes further by supporting more advanced smart contract capabilities through:
- CashScript: A high-level programming language that compiles into Bitcoin Script, making it easier to build decentralized applications (dApps).
- Wormhole Protocol: Enables token creation and issuance on the BCH blockchain, similar to ERC-20 tokens on Ethereum.
These tools allow developers to create tokens, NFTs, and dApps directly on the BCH chain—giving it an edge in utility over standard Bitcoin transactions.
Mining Mechanics and Profitability
Both BTC and BCH use the Proof-of-Work (PoW) consensus mechanism and the SHA-256 hashing algorithm, meaning miners can technically switch between them using the same hardware.
However, there’s a critical difference in difficulty adjustment:
- Bitcoin: Adjusts mining difficulty every 2016 blocks (~two weeks).
- Bitcoin Cash: Adjusts every 6 blocks (~one hour).
This frequent adjustment makes BCH mining more responsive to changes in network hash rate, allowing miners to maintain profitability even during sudden shifts in competition. For smaller mining operations, this smooth adjustment reduces equipment strain and extends hardware lifespan.

Frequently Asked Questions (FAQ)
Q: Is Bitcoin Cash just a copy of Bitcoin?
No. While Bitcoin Cash shares Bitcoin’s transaction history up to the fork date, it has different technical rules—especially regarding block size and scalability. It's an independent cryptocurrency with its own development roadmap.
Q: Can Bitcoin Cash replace Bitcoin?
Unlikely in the near term. Bitcoin has stronger brand recognition, wider adoption, and greater institutional support. BCH may serve as efficient digital cash, but BTC remains the dominant store of value.
Q: Why did the Bitcoin community split?
The split occurred due to disagreements over scalability. Some believed larger blocks were necessary for fast, cheap transactions; others favored off-chain solutions to preserve decentralization and security.
Q: Which is better for everyday payments?
Bitcoin Cash generally offers lower fees and faster confirmations, making it more suitable for daily transactions. However, merchant acceptance is still far more widespread for Bitcoin.
Q: Does Bitcoin Cash have a future?
Yes. With ongoing development in smart contracts and tokenization via Wormhole and CashScript, BCH continues to innovate. Its focus on usability keeps it relevant in the evolving crypto landscape.
Q: Are both coins secure?
Both networks are secure due to their PoW consensus and active mining communities. However, Bitcoin’s larger hash rate makes it more resistant to potential attacks than BCH.
Price Predictions and Future Outlook
In early 2020, Bitcoin was valued at around $7,000**, while Bitcoin Cash traded near **$160. By February, BTC approached $9,300**, and BCH rose to **$370, showing renewed investor confidence.
Experts predicted that by the end of 2020:
- Bitcoin could reach $20,000
- Bitcoin Cash might hit $500
While these targets were eventually surpassed in later bull markets, the trend highlights growing optimism for both assets—albeit at different scales.
Looking ahead, Bitcoin is expected to maintain its dominance as the flagship cryptocurrency. Meanwhile, Bitcoin Cash aims to solidify its role as fast, low-cost digital cash, especially in regions where financial inclusion is a priority.

Final Thoughts
Bitcoin and Bitcoin Cash represent two visions of what cryptocurrency can be: one as digital gold, prioritizing security and scarcity; the other as electronic cash, emphasizing speed and affordability. Neither is inherently superior—their value depends on use case and user preference.
For investors and users alike, understanding these differences is key to making informed decisions in the dynamic world of digital assets.
