Bitcoin Cash (BCH) emerged as a significant cryptocurrency following a contentious hard fork from the original Bitcoin blockchain in August 2017. Created by a coalition of developers, miners, entrepreneurs, and investors, BCH was designed to address scalability concerns and high transaction fees that plagued Bitcoin at the time. It positions itself as a peer-to-peer electronic cash system optimized for everyday transactions.
The Origins of Bitcoin Cash
In 2017, Bitcoin faced mounting challenges related to network congestion. Lengthy transaction confirmation times and rising fees undermined its original vision of offering fast, low-cost payments. This led to intense debate within the Bitcoin community regarding the best path forward—particularly whether to increase the block size limit.
Since Bitcoin operates as a decentralized network, protocol changes require broad consensus. When agreement couldn’t be reached, proponents of larger blocks initiated a hard fork, resulting in the creation of Bitcoin Cash. This new network enabled greater transaction throughput and reduced fees by increasing the block size.
Many in the BCH community believe the project better reflects Satoshi Nakamoto’s initial concept of electronic cash, as described in the original Bitcoin whitepaper. They argue that its design makes it more practical for daily transactions compared to Bitcoin.
How Bitcoin Cash Differs from Bitcoin
Although both networks share a common origin, several technical distinctions set them apart:
- Block Size: Bitcoin Cash increased its block size from Bitcoin’s 1 MB to 8 MB at launch, later expanding to 32 MB in 2018. This allows more transactions per block, improving throughput.
- Difficulty Adjustment: BCH adjusts mining difficulty after every block using a Difficulty Adjustment Algorithm (DAA), unlike Bitcoin’s 2016-block interval.
- SegWit and Schnorr Signatures: Bitcoin Cash did not implement Segregated Witness (SegWit), a solution adopted by Bitcoin to improve scalability. Instead, BCH incorporated Schnorr Signatures in 2019, enhancing privacy and efficiency in transaction signing.
- Consensus and Supply: Both use Proof of Work (PoW) and have a fixed supply of 21 million coins. BCH also maintains a 10-minute target block time.
Notably, during the fork, Bitcoin holders received an equivalent amount of BCH on the new chain, based on their existing BTC balances.
Key Features of Bitcoin Cash
Bitcoin Cash is built for utility and efficiency. Its core characteristics include:
- Fast transaction confirmations and minimal fees
- Support for basic smart contracts and token issuance
- Ongoing development focused on usability and merchant adoption
- A commitment to on-chain scaling rather than second-layer solutions
These features aim to make BCH suitable for use as digital cash for everyday purchases, microtransactions, and remittances.
Bitcoin Cash in Practice
While BCH offers technical advantages for payments, its adoption has been mixed. Some online and physical merchants accept Bitcoin Cash, attracted by its low fees and rapid settlement. However, acceptance is not yet universal, and some merchant listings may be outdated.
Users can store BCH in a variety of wallets, including mobile, desktop, and hardware options. It is crucial to remember that Bitcoin and Bitcoin Cash are separate networks—sending funds between BTC and BCH addresses will result in loss of funds.

The Bitcoin SV Fork
In November 2018, Bitcoin Cash itself underwent a hard fork, leading to the creation of Bitcoin SV (BSV). Driven by Craig Wright and Calvin Ayre, BSV further increased the block size limit to 2 GB. However, it failed to gain significant support, partly due to controversy surrounding Wright’s claim to be Satoshi Nakamoto.
Frequently Asked Questions
What is Bitcoin Cash?
Bitcoin Cash is a cryptocurrency that split from Bitcoin in 2017. It was created to offer faster transactions and lower fees by increasing the block size, making it more practical for daily payments.
How is Bitcoin Cash different from Bitcoin?
The key difference is the block size limit—32 MB for BCH versus 1 MB for BTC. BCH also uses a different difficulty adjustment algorithm and does not implement SegWit. Both have a 21 million coin cap and use Proof of Work.
Can I use the same wallet for Bitcoin and Bitcoin Cash?
No. Bitcoin and Bitcoin Cash are separate networks with different addresses. Always use a wallet that explicitly supports BCH to avoid permanent loss of funds.
Is Bitcoin Cash more scalable than Bitcoin?
In terms of on-chain capacity, yes. Larger blocks allow more transactions per second. However, Bitcoin uses additional solutions like SegWit and the Lightning Network for scalability.
Who supports Bitcoin Cash?
BCH is supported by a community of developers, companies, and users who believe in its vision of electronic cash. It is also listed on major cryptocurrency exchanges.
What is the future of Bitcoin Cash?
Development continues to focus on improving usability, scalability, and merchant adoption. Its future will depend on broader acceptance and use in real-world transactions.
Conclusion
Bitcoin Cash represents an important alternative vision for cryptocurrency—one that prioritizes transactional efficiency and everyday usability. While it has not surpassed Bitcoin in market dominance or security, it remains a relevant player with a dedicated community and clear use case. For those interested in a practical digital cash system, BCH offers a compelling option worth considering.
