About Bitcoin Cash (BCH)
What Is Bitcoin Cash (BCH)?
Bitcoin Cash (BCH) is a decentralized peer-to-peer electronic cash system designed for fast, low-cost global payments. It was created in August 2017 as a hard fork of Bitcoin after disagreements within the Bitcoin community about scaling and transaction fees.
The split occurred at Bitcoin block 478,558, resulting in two separate networks: Bitcoin (BTC) and Bitcoin Cash (BCH). Supporters of Bitcoin Cash favored larger blocks to fit more transactions on-chain and preserve a "digital cash" use case.
Bitcoin Cash shares Bitcoin's Proof-of-Work model and 21 million supply cap, but differs in block size limits and scaling philosophy.

How Bitcoin Cash Works
Bitcoin Cash works similarly to Bitcoin, with protocol-level differences focused on throughput:
- Larger Block Size
At launch, BCH increased the block size limit above Bitcoin's then-effective limits, and later upgrades increased capacity further. Larger blocks can enable:
- More transactions per block
- Higher throughput
- Lower on-chain transaction fees during normal conditions
This design emphasizes on-chain scaling rather than relying primarily on second-layer payment networks.
- Proof-of-Work (PoW)
BCH uses Proof of Work secured by the SHA-256 hashing algorithm, like Bitcoin. Miners compete to produce blocks and earn block rewards and transaction fees. Mining is competitive and generally requires specialized ASIC hardware.
- Fixed Supply and Halving
Bitcoin Cash has a fixed maximum supply of 21 million coins. Like Bitcoin, BCH undergoes periodic halving events that reduce the block subsidy over time, continuing until issuance approaches zero.
What Makes Bitcoin Cash Unique?
Bitcoin Cash is often described as:
- Focused on low-fee, on-chain payments
- Designed to support microtransactions
- More permissive about block size increases than BTC
- Oriented toward merchant payments and payments usability
Supporters argue BCH is better suited for daily payments due to lower fees and simpler on-chain settlement in typical conditions.
Critics argue that larger blocks can increase storage and bandwidth requirements, potentially raising the cost of running a full node, and that adoption has been lower compared to Bitcoin.
BCH Tokenomics
BCH tokenomics broadly follow Bitcoin's issuance model:
- Maximum supply: 21 million BCH
- Consensus: Proof-of-Work (SHA-256)
- Issuance: reduced over time via halvings
Use Cases of Bitcoin Cash
Common BCH use cases include:
- Peer-to-peer payments
- Merchant payments (online and in-store)
- Remittances and cross-border transfers
- Microtransactions
- Token issuance and experimentation
Bitcoin Cash has also seen privacy-enhancing tools and techniques in its ecosystem, including CashShuffle and CashFusion.
Hard Fork History
Bitcoin Cash has experienced additional splits over time. Notable events include:
- November 2018: a split that resulted in Bitcoin Cash (BCH) and Bitcoin SV (BSV)
- November 2020: a split related to funding and development policy debates (often associated with Bitcoin Cash ABC, later rebranded)
Despite forks, the BCH network has continued under the Bitcoin Cash name.
How Bitcoin Cash Is Secured
Bitcoin Cash security relies on:
- Proof-of-Work mining
- Distributed node validation
- The SHA-256 hashing algorithm
Because BCH uses SHA-256, miners can shift hash power between BTC and BCH depending on profitability and market dynamics. In general, higher hash rate increases resistance to certain attacks.
Risks and Considerations
Key considerations include:
- Lower adoption relative to Bitcoin in many markets
- Historical chain splits and governance disputes
- Competition from Layer 2 payment networks (e.g., Lightning Network) and other L1 chains
- Mining centralization concerns
- Lower brand dominance compared to BTC
Why Bitcoin Cash Matters
Bitcoin Cash represents a different approach to Bitcoin's scaling debate, prioritizing on-chain scaling and payments usability over second-layer solutions.
For users who want low-fee, direct on-chain transfers, BCH aims to function as practical digital cash.
Where Can You Buy Bitcoin Cash (BCH)?
BCH is widely listed on major centralized cryptocurrency exchanges. Availability, supported pairs, and payment methods vary by jurisdiction.
Major Centralized Exchanges (CEX)
BCH is commonly listed on exchanges such as:
Common trading pairs include BCH/USDT, BCH/USD, BCH/EUR, and BCH/BTC (availability varies).
Storage Options After Purchase
After buying BCH, it can be stored:
- On an exchange (custodial)
- In software wallets that support Bitcoin Cash
- On hardware wallets such as Ledger and Trezor
You can view transactions and addresses using a BCH block explorer such as Blockchair.
