Bitcoin Cash (BCH) emerged from a pivotal moment in cryptocurrency history — a moment defined by technical debate, ideological division, and the quest to scale digital money for real-world use. Born out of a hard fork of the original Bitcoin (BTC) blockchain in August 2017, Bitcoin Cash was created with a clear mission: to restore Bitcoin’s original purpose as a peer-to-peer electronic cash system capable of fast, low-cost transactions.
While Bitcoin has increasingly evolved into a store of value — often compared to “digital gold” — Bitcoin Cash aims to function as “digital cash,” prioritizing everyday usability over scarcity and speculative value.
The Origins of Bitcoin Cash: A Hard Fork Explained
The Bitcoin network launched in January 2009 following the mining of the genesis block, marking the beginning of decentralized digital currency. Designed by an anonymous figure known as Satoshi Nakamoto, Bitcoin introduced a revolutionary way to transfer value without intermediaries. However, as adoption grew, so did challenges related to scalability.
By 2017, the Bitcoin network faced significant congestion. With a maximum block size of just 1MB, the network could process only about seven transactions per second. During periods of high demand, this led to slow confirmation times and rising transaction fees — sometimes exceeding $50 during peak usage.
Two primary solutions emerged within the developer community:
- On-chain scaling: Increase the block size to allow more transactions per block.
- Off-chain scaling: Implement second-layer solutions like the Lightning Network to handle transactions outside the main chain.
The inability to reach consensus resulted in a hard fork — a permanent divergence in the blockchain. On August 1, 2017, nodes that adopted the new rules split from the original Bitcoin chain, creating Bitcoin Cash (BCH) with an initial block size limit of 8MB (later increased to 32MB).
This meant that BCH could confirm more transactions per block, significantly reducing fees and wait times. For supporters, this was a return to Satoshi’s original vision of a usable, decentralized cash system.

Why Bitcoin Cash Exists: Speed, Cost, and Usability
One of the core arguments behind Bitcoin Cash is practicality. If cryptocurrency is to replace traditional payment systems, it must be able to compete with them in speed and cost.
Here’s how Bitcoin Cash compares:
| Metric | Bitcoin (BTC) | Bitcoin Cash (BCH) | Visa (for context) |
|---|---|---|---|
| Transactions Per Second (TPS) | ~7 | ~116 | ~24,000 |
While neither BTC nor BCH comes close to Visa’s throughput, BCH’s larger blocks enable faster processing and lower fees — often less than $0.01 per transaction. This makes it far more viable for micropayments and daily purchases.
Additionally, developers implemented technical improvements such as:
- Replay protection: Prevents transactions on one chain from being duplicated on the other.
- SigHash optimization: Reduces data verification requirements, improving efficiency.
- Adjustable block size: Allows flexibility in handling traffic surges.
These enhancements support Bitcoin Cash’s goal: to be used, not just held.
The Great Debate: BTC vs. BCH — Philosophy and Vision
The split between Bitcoin and Bitcoin Cash wasn’t just technical — it was deeply ideological.
The Case for Bitcoin (BTC)
BTC advocates believe that security and decentralization are paramount. They argue that keeping blocks small ensures that individual users can still run full nodes on consumer hardware, preserving network decentralization. Larger blocks, they warn, could lead to centralization as only well-resourced entities could afford the infrastructure needed to validate them.
Moreover, many see BTC’s limited supply and slow transaction speed as features, not bugs. By functioning as digital gold, Bitcoin becomes a hedge against inflation and a long-term store of value — especially appealing in times of economic uncertainty.
The Case for Bitcoin Cash (BCH)
BCH supporters counter that without usability, Bitcoin loses its purpose. They cite early Bitcoin whitepaper references to “electronic cash” and peer-to-peer payments as evidence that Nakamoto envisioned a currency for spending, not hoarding.
To them, increasing block size is the most straightforward path to scalability. They emphasize that off-chain solutions add complexity and may reintroduce trust elements — contradicting the spirit of decentralization.

Controversy and Confusion: Naming Rights and Identity
A major source of tension has been the name itself. Critics argue that calling it “Bitcoin Cash” creates confusion and misleads newcomers into thinking it’s the “real” Bitcoin. Some view this as opportunistic branding rather than honest differentiation.
Further controversy arose when Craig Wright — an Australian computer scientist who controversially claimed to be Satoshi Nakamoto — endorsed Bitcoin Cash as the true continuation of Bitcoin. His claims were met with widespread skepticism and backlash from both communities.
Later, Wright distanced himself from BCH and launched Bitcoin SV (Satoshi Vision) in November 2018, asserting that BSV better aligned with Nakamoto’s original design. This only deepened the fragmentation within the ecosystem.
Despite these disputes, both BTC and BCH have found their niches:
- Bitcoin (BTC): Preferred for investment, savings, and institutional adoption.
- Bitcoin Cash (BCH): Favored for payments, remittances, and merchant transactions.

Frequently Asked Questions (FAQ)
What is a hard fork in blockchain?
A hard fork is a permanent change to a blockchain’s protocol that makes previously invalid blocks or transactions valid — or vice versa. Nodes running the old software will no longer be compatible with the new chain, resulting in a split.
Can I own both Bitcoin and Bitcoin Cash after a fork?
Yes. When the Bitcoin Cash fork occurred in 2017, anyone who held Bitcoin at the time automatically received an equivalent amount of Bitcoin Cash. Wallets supporting both currencies allowed users to access both balances.
Is Bitcoin Cash more scalable than Bitcoin?
Yes, due to its larger block size (up to 32MB), Bitcoin Cash can process more transactions per block than Bitcoin’s 1MB limit. This results in faster confirmation times and lower fees under normal network conditions.
Does Bitcoin Cash have the same supply cap as Bitcoin?
Yes. Like Bitcoin, Bitcoin Cash has a maximum supply cap of 21 million coins. This scarcity helps maintain its long-term value proposition despite its focus on transactional use.
Why do some people dislike Bitcoin Cash?
Critics argue that larger blocks compromise decentralization by making it harder for individuals to run full nodes. Others object to its use of the “Bitcoin” name, seeing it as misleading or disrespectful to the original project.
Can I use Bitcoin Cash for everyday purchases?
Yes. Many online merchants, gaming platforms, and remittance services accept BCH due to its low fees and fast processing times. Its utility as “digital cash” is actively promoted by its community.

Conclusion
Bitcoin Cash represents a bold attempt to rethink what cryptocurrency can be. While it may never surpass Bitcoin in market dominance or cultural significance, it offers a compelling alternative for those who prioritize usability over pure store-of-value properties.
Whether you see it as a necessary evolution or a controversial offshoot, one thing is clear: there’s more than one way to build digital money. As the ecosystem continues to grow, both BTC and BCH will likely play distinct but complementary roles in shaping the future of finance.
