Bitcoin Cash (BCH) often sparks curiosity among cryptocurrency enthusiasts and investors alike. While it shares a name and origin with Bitcoin (BTC), its purpose, design, and vision diverge in significant ways. To truly understand Bitcoin Cash, we must first explore the concept of blockchain "hard forks," examine how BCH emerged from Bitcoin, and compare the key differences between these two major digital currencies.
This article will guide you through the essential aspects of Bitcoin Cash, including its technical foundation, operational mechanics, and unique value proposition — all while maintaining clarity and relevance for both newcomers and seasoned crypto participants.
Understanding Hard Forks in Blockchain
Before diving into Bitcoin Cash, it’s crucial to understand what a hard fork is in the context of blockchain technology.
Bitcoin, as the original cryptocurrency, operates on a decentralized network governed by consensus rules. As adoption grew, so did transaction volume — leading to slower processing times and rising fees. With Bitcoin limited to processing only 3–7 transactions per second (compared to tens of thousands on traditional payment networks like Visa), congestion became a serious issue.
This bottleneck led to intense debate within the Bitcoin community: Should the block size be increased to allow more transactions per block?
The disagreement resulted in a hard fork — a permanent divergence in the blockchain where new rules are incompatible with the old ones. Unlike a soft fork, which maintains backward compatibility, a hard fork creates two separate chains: one following the old rules and another adopting new ones.
In this split, holders of the original cryptocurrency automatically receive an equivalent amount of the new coin on the forked chain. This is exactly how Bitcoin Cash (BCH) was born — not as a completely independent project, but as a direct result of ideological and technical disagreements over Bitcoin’s scalability.

What Is Bitcoin Cash (BCH)?
Bitcoin Cash (BCH) emerged on August 1, 2017, when a group of developers, miners, and entrepreneurs broke away from the Bitcoin network to create a version of Bitcoin that prioritized fast, low-cost peer-to-peer transactions.
Also known as Bitcoin ABC (Adjustable Blocksize Cap), BCH was designed to fulfill what many believe was Satoshi Nakamoto’s original vision: a decentralized electronic cash system usable for everyday payments.
While BTC has increasingly been treated as “digital gold” — a store of value — BCH aims to function as digital cash, emphasizing practicality in real-world transactions.
How Does Bitcoin Cash (BCH) Work?
Since Bitcoin Cash originated from Bitcoin’s open-source codebase, it inherits many of the same core features:
- Consensus Mechanism: Like BTC, BCH uses Proof of Work (PoW), allowing miners to validate transactions and secure the network.
- Block Time: The average time to mine a new block is approximately 10 minutes, matching Bitcoin’s rhythm.
- Total Supply Cap: Both cryptocurrencies have a maximum supply of 21 million coins, ensuring scarcity.
- Halving Events: Every 210,000 blocks (roughly every four years), the block reward is cut in half. As of now, the current block reward for BCH mining is 6.25 BCH per block.
These similarities ensure that BCH remains familiar to users and developers already experienced with Bitcoin’s ecosystem.
Key Differences Between Bitcoin (BTC) and Bitcoin Cash (BCH)
Despite their shared roots, BTC and BCH differ significantly in philosophy and technical implementation. Here are the most important distinctions:
1. Block Size and Scalability
The primary innovation of Bitcoin Cash is its larger block size:
- Bitcoin (BTC): Blocks are capped at 1 MB, limiting the number of transactions processed per second.
- Bitcoin Cash (BCH): Block size starts at 8 MB and has been expanded up to 32 MB, allowing far more transactions per block.
This approach enables BCH to scale on-chain, meaning it handles more transactions directly on the blockchain rather than relying on secondary layers like Bitcoin’s Lightning Network.
Larger blocks mean faster confirmation times and reduced network congestion — making BCH better suited for frequent, small-value transactions.
2. Transaction Fees and Speed
Due to its larger capacity, Bitcoin Cash typically offers:
- Lower transaction fees
- Faster processing times
For example, while BTC fees can spike during peak usage (sometimes exceeding $10), BCH fees often remain under $0.01 — making it ideal for microtransactions or cross-border remittances.
This efficiency supports BCH’s goal of becoming a practical medium of exchange rather than just a long-term investment.
3. Use Case and Vision
- Bitcoin (BTC): Viewed primarily as a store of value — often called “digital gold.” Its limited supply and high market cap make it attractive for wealth preservation.
- Bitcoin Cash (BCH): Designed as peer-to-peer electronic cash, aiming to replace traditional payment methods with fast, cheap, and globally accessible transactions.
Many in the crypto community argue that BCH adheres more closely to Satoshi Nakamoto’s original whitepaper vision than BTC does today.
Four Key Features of Bitcoin Cash (BCH)
To summarize, here are the defining characteristics of Bitcoin Cash:
- Built on Bitcoin’s Original Code: Retains core security and decentralization principles.
- Scalable via Larger Blocks: Supports blocks up to 32 MB for higher throughput.
- Uses Proof of Work (PoW): Ensures mining decentralization and network security.
- Fixed Supply of 21 Million Coins: Maintains scarcity and resistance to inflation.
These traits position BCH as a robust alternative for users seeking efficient blockchain-based payments.

Frequently Asked Questions (FAQ)
Q: Is Bitcoin Cash just a copy of Bitcoin?
A: While BCH originated from Bitcoin’s codebase, it has evolved with distinct upgrades — especially in block size and transaction speed — giving it unique functionality.
Q: Can I mine Bitcoin Cash?
A: Yes. Using ASIC miners compatible with SHA-256 hashing algorithms (the same used by BTC), individuals and mining pools can participate in securing the BCH network.
Q: Do I need a wallet to hold BCH?
A: Absolutely. You’ll need a cryptocurrency wallet that supports BCH. Many popular wallets like Electron Cash, Trust Wallet, and Ledger offer full BCH compatibility.
Q: Are Bitcoin Cash transactions irreversible?
A: Like most blockchain transactions, once confirmed, BCH transfers cannot be reversed — emphasizing the importance of verifying addresses before sending funds.
Q: Why did the hard fork happen?
A: The split occurred due to disagreements over scalability solutions. Some believed increasing block size was the best path; others favored off-chain scaling methods like the Lightning Network.
Q: Is Bitcoin Cash more secure than Bitcoin?
A: BTC currently has greater hash power and network security due to its larger market presence. However, BCH still uses strong cryptographic protocols and remains secure against most attack vectors.
Trading Bitcoin Cash via CFDs
You don’t need to own actual BCH to benefit from its price movements. With Contract for Difference (CFD) trading, investors can speculate on BCH’s price without holding the underlying asset.
CFDs allow traders to:
- Go long (buy) if they expect prices to rise
- Go short (sell) if they anticipate a decline
- Use leverage to amplify potential returns (and risks)
This method offers flexibility, especially for those interested in short-term trading strategies or hedging existing crypto positions.
