Bitcoin Cash (BCH) has been one of the most debated cryptocurrencies since its emergence in 2017. Born from a hard fork of the original Bitcoin (BTC) blockchain, it sparked intense discussions about scalability, decentralization, and what it truly means to be “Bitcoin.” In this comprehensive guide, we’ll explore the origins of Bitcoin Cash, its purpose, how it differs from BTC, and whether it can be considered the “real” Bitcoin.
Our goal is to present an objective, well-researched analysis that helps you understand the technical and philosophical foundations of BCH—without pushing any investment agenda. Let’s dive in.
Understanding Blockchain Forks: The Foundation of Bitcoin Cash
Before we explore Bitcoin Cash itself, it's essential to understand blockchain forks, as they are central to BCH’s creation.
In cryptocurrency, a fork refers to a change in a blockchain’s protocol. There are two main types:
- Soft Forks: Backward-compatible updates. Older nodes can still interact with the network after the update.
- Hard Forks: Non-backward-compatible changes. All participants must upgrade to the new rules, or they risk operating on a separate chain.
Bitcoin Cash is the result of a hard fork that occurred on August 1, 2017. This split happened because of a fundamental disagreement within the Bitcoin community about how to scale the network.

What Is Bitcoin Cash?
Bitcoin Cash (BCH) is a peer-to-peer electronic cash system created as a hard fork of Bitcoin. Its primary goal was to restore Bitcoin’s original vision as a fast, low-cost payment network—something many believed BTC had lost due to rising fees and slow transaction times.
When Bitcoin Cash launched, every holder of Bitcoin received an equal amount of BCH at no extra cost. Since then, the two networks have evolved independently.
Despite sharing Bitcoin’s early history, BCH has taken a different technological path—most notably through larger block sizes.
Why Was Bitcoin Cash Created?
By mid-2017, Bitcoin faced a major scalability crisis:
- Transaction backlog: Thousands of unconfirmed transactions.
- High fees: Some fees exceeded $40 per transaction.
- Slow confirmations: Transactions sometimes took days to process.
These issues stemmed from Bitcoin’s 1MB block size limit, which restricted the number of transactions per block (approximately every 10 minutes). With only enough space for about 4–7 transactions per second, Bitcoin struggled to compete with traditional payment systems like Visa, which handles over 25,000 transactions per second.
The debate over how to fix this split the community into two camps:
- Increase block size → Proponents believed bigger blocks would allow more transactions, lower fees, and faster processing.
- Improve efficiency without increasing block size → Advocates supported solutions like SegWit (Segregated Witness) and the Lightning Network, which compress transaction data and move some transactions off-chain.
Bitcoin Cash emerged from the first camp—those who wanted larger blocks.
The Core Difference: Block Size Expansion
The defining feature of Bitcoin Cash is its larger block size:
- Bitcoin (BTC): 1MB blocks (increased to ~4MB with SegWit).
- Bitcoin Cash (BCH): Started at 8MB, later increased to 32MB.
Larger blocks mean more transactions can be processed per block, leading to:
- Lower transaction fees
- Faster confirmation times
- Higher throughput
For example, BCH typically charges fractions of a cent per transaction—even during peak usage.
This design choice aligns with the belief that on-chain scaling is the most straightforward and secure way to make cryptocurrency usable for everyday payments.

Criticism of Larger Blocks
While increasing block size seems like a simple fix, critics argue it comes with trade-offs:
- Centralization risk: Larger blocks require more storage and bandwidth. Over time, this could exclude smaller nodes and miners, concentrating power in the hands of large mining farms.
- Network strain: Nodes in regions with slower internet may struggle to download and verify large blocks quickly.
- Security implications: If fewer nodes can participate, the network becomes less decentralized—and thus less resilient.
The Bitcoin Core team argued that off-chain scaling (like the Lightning Network) preserves decentralization while improving speed and cost. They prioritized keeping the network accessible to individual users running full nodes on consumer hardware.
Bitcoin Cash supporters counter that usability comes first—and that practicality should not be sacrificed for ideological purity.
The 2018 Bitcoin Cash Fork: A Community Divided
Ironically, just over a year after splitting from Bitcoin, the Bitcoin Cash community faced its own hard fork in November 2018.
The split was driven by ideological differences between two factions:
- Bitcoin ABC (supported by Roger Ver and Bitmain): Favored moderate upgrades and staying close to Satoshi’s original vision.
- Bitcoin SV (Satoshi Vision) (led by Craig Wright): Claimed to restore what Wright said was Nakamoto’s true intent, including plans for massive block sizes (up to 128MB or more).
The result? Another hard fork: BCH split into BCH and BSV.
Market sentiment largely favored BCH over BSV. To date, BCH maintains a significantly higher market capitalization and broader exchange support.
Is Bitcoin Cash the Real Bitcoin?
This is the million-dollar question—and the answer depends on your definition of “real.”
From a technical standpoint:
- BCH shares Bitcoin’s early blockchain history.
- It uses similar consensus rules (Proof-of-Work).
- It aims to be digital cash for daily use.
From a philosophical standpoint:
- BTC supporters see Bitcoin as digital gold—a store of value with strong security and decentralization.
- BCH supporters view it as electronic cash—meant for spending, not hoarding.
So, is BCH the real Bitcoin?
No—not in the sense of being the original or dominant chain. BTC remains the most widely adopted, valuable, and recognized cryptocurrency. However, BCH is a legitimate evolution of Bitcoin’s codebase with a clear mission: fast, cheap, peer-to-peer payments.
It’s not “fake,” but it’s also not BTC.
Key Differences Between BTC and BCH
| Feature | Bitcoin (BTC) | Bitcoin Cash (BCH) |
|---|---|---|
| Block Size | ~1–4 MB | Up to 32 MB |
| Primary Use Case | Store of value ("digital gold") | Peer-to-peer payments ("digital cash") |
| Transaction Fees | Higher ($1–$50 during peaks) | Extremely low (< $0.01) |
| Scaling Approach | Off-chain (Lightning Network) | On-chain (larger blocks) |
| Community Focus | Security & decentralization | Usability & transaction capacity |
Frequently Asked Questions (FAQ)
Q: Can I still use Bitcoin Cash for everyday purchases?
Yes. While adoption isn’t as widespread as BTC, several merchants accept BCH for goods and services—especially in tech-savvy communities and online stores focused on crypto payments.
Q: Did Bitcoin Cash succeed in fixing Bitcoin’s scalability issues?
Technically, yes. BCH handles more transactions per second at lower costs than BTC. However, lower adoption limits its real-world impact compared to its potential.
Q: Who created Bitcoin Cash?
Bitcoin Cash wasn’t created by a single person. It was initiated by a coalition of miners, developers, and investors—including Bitmain co-founder Jihan Wu and investor Roger Ver—who supported larger blocks.
Q: Is Bitcoin Cash more decentralized than Bitcoin?
Not necessarily. While both networks rely on Proof-of-Work, BCH’s larger blocks may favor well-resourced mining operations, potentially increasing centralization over time.
Q: Can I mine Bitcoin Cash?
Yes. BCH uses the same SHA-256 algorithm as BTC, so ASIC miners designed for Bitcoin can also mine BCH—though profitability depends on difficulty and price.
Q: What happened to the “Bitcoin” name claim?
Early BCH advocates referred to it as “Bitcoin,” arguing BTC had deviated from Satoshi’s vision. However, due to market recognition, “Bitcoin” now universally refers to BTC.
Final Thoughts: Where Does Bitcoin Cash Stand Today?
Bitcoin Cash remains a top-tier cryptocurrency by market cap and continues to advocate for on-chain scaling. While it hasn’t replaced BTC as the dominant digital currency, it serves as an important alternative for those who prioritize low-cost transactions and believe in larger-block philosophies.
It’s not the “real” Bitcoin in terms of market dominance or origin—but it is a meaningful chapter in the ongoing evolution of blockchain technology.
Whether you see it as a necessary innovation or a failed experiment depends on your values: security and scarcity versus speed and affordability.
