Bitcoin vs Bitcoin Cash vs Bitcoin SV: The Three Bitcoin Variants
2026-09-23
Three cryptocurrencies carry the Bitcoin name, but each one exists because its community disagreed on what Bitcoin should become. Bitcoin (BTC) remains the original chain and the largest cryptocurrency by market cap.
Bitcoin Cash (BCH) forked in 2017 to pursue bigger blocks and cheaper payments. Bitcoin SV (BSV) split from Bitcoin Cash in 2018 to push block sizes even further and position itself as an enterprise data ledger.
Here is what separates them, why each fork happened, and how they compare today.
Key Takeaways
- Bitcoin prioritises security and decentralisation with a conservative block size, relying on Layer 2 solutions like the Lightning Network for scaling transaction throughput.
- Bitcoin Cash forked in August 2017 to increase the block size to 32 MB, targeting faster and cheaper on chain payments without relying on off chain layers.
- Bitcoin SV forked from Bitcoin Cash in November 2018 with the goal of restoring what its proponents call the "original Satoshi vision," pushing block sizes to multiple gigabytes for enterprise scale data applications.
What Is Bitcoin (BTC)?
Bitcoin is the original cryptocurrency, launched in January 2009 by the pseudonymous developer Satoshi Nakamoto. It operates as a peer to peer electronic cash system secured by proof of work mining using the SHA 256 algorithm.
The total supply is capped at 21 million BTC, with new coins entering circulation through mining rewards that halve approximately every four years.
Bitcoin's base layer processes approximately seven transactions per second with a block size limit originally set at 1 MB.
The introduction of Segregated Witness (SegWit) in August 2017 effectively increased block capacity to around 4 MB of block weight by separating signature data from transaction data. This was a technical compromise: increase throughput without raising the raw block size limit.
For higher volume payments, Bitcoin relies on Layer 2 solutions like the Lightning Network. The Lightning Network creates off chain payment channels that can process thousands of transactions per second at near zero fees, settling final balances back to the Bitcoin base layer.
This layered approach keeps the base chain lightweight and accessible for node operators worldwide, which supporters argue preserves decentralisation.
Bitcoin's market position is dominant. It holds the largest market cap in crypto, serves as the primary trading pair across exchanges, and has been adopted as a reserve asset by institutions and governments.
Its primary narrative has shifted over the years from digital cash to digital gold: a store of value and inflation hedge.
What Is Bitcoin Cash (BCH)?
Bitcoin Cash forked from Bitcoin on 1 August 2017 at block height 478,558. The fork was the result of years of debate within the Bitcoin community over how to scale the network, commonly referred to as the "Blocksize War."
One faction argued for keeping blocks small and scaling through Layer 2 solutions. The other argued that increasing the block size directly was simpler, faster, and more aligned with Satoshi's original whitepaper vision of peer to peer electronic cash.
Bitcoin Cash chose the bigger blocks path. The initial fork raised the block size limit to 8 MB, which was later increased to 32 MB.
This allows Bitcoin Cash to process significantly more transactions per block than BTC, with theoretical throughput exceeding 100 transactions per second onchain.
Transaction fees on BCH are typically a fraction of a cent, making it more practical for everyday payments and microtransactions.
BCH shares the same SHA 256 mining algorithm and 21 million supply cap as Bitcoin. The key philosophical difference is that Bitcoin Cash positions itself as a medium of exchange first.
Its supporters argue that a currency must be usable for daily transactions to achieve mainstream adoption, and that Layer 2 solutions add unnecessary complexity. The project is governed by multiple independent development teams rather than a single core group.
What Is Bitcoin SV (BSV)?
Bitcoin SV (Satoshi Vision) forked from Bitcoin Cash on 15 November 2018, following an internal dispute within the BCH community over the network's future direction.
The fork was led by Craig Wright, an Australian computer scientist who has claimed to be Satoshi Nakamoto, and Calvin Ayre, a tech entrepreneur.
The split is often called the "Hash War" because both sides competed for mining power to establish their chain as the legitimate continuation of Bitcoin Cash.
BSV's defining feature is its approach to block size. Rather than setting a fixed cap, BSV has removed block size limits entirely, allowing blocks to scale to multiple gigabytes.
The network has produced blocks exceeding 4 GB. The goal is to handle not just payment transactions but also enterprise data, tokenisation, and smart contracts at massive scale, all on the base layer with no need for Layer 2 solutions.
BSV positions itself as an enterprise blockchain and data ledger rather than primarily a payments network. Its proponents argue that only unbounded block sizes can support the transaction volumes needed for global adoption across industries.
Critics counter that extremely large blocks require expensive hardware to run full nodes, which concentrates network operation among a small number of well funded entities and reduces decentralisation.
BSV has also faced controversy due to Wright's unproven claims of being Bitcoin's creator, which has led to scepticism and delistings from several major exchanges over the years.

How Do BTC, BCH, and BSV Compare Technically?
All three networks share the same foundational DNA: SHA 256 proof of work, a 21 million coin supply cap, and approximately 10 minute block times. The differences emerge in block size policy, scaling philosophy, and network priorities.
Bitcoin's effective block weight of 4 MB (via SegWit) keeps node requirements low. Running a full Bitcoin node is possible on a basic home computer with modest bandwidth, which supporters argue is essential for censorship resistance and trustless verification.
The trade off is limited base layer throughput, compensated by the Lightning Network and other Layer 2 protocols.
Bitcoin Cash's 32 MB block size strikes a middle ground. It offers substantially more on chain capacity than BTC while keeping node requirements within reach of small businesses and dedicated individuals.
BCH does not rely on Layer 2 for everyday transactions and instead opts for direct on chain scaling with incremental block size increases as demand grows.
Bitcoin SV takes the most aggressive position. With no enforced block size cap, it prioritises raw throughput above all else.
This approach can handle massive transaction volumes on the base layer but requires significantly more storage, bandwidth, and processing power to operate a full node. The result is a network where mining and node operation are concentrated among fewer, larger participants.
Because all three share SHA 256, miners can switch between BTC, BCH, and BSV depending on profitability. Bitcoin commands the vast majority of total SHA 256 hash rate, which gives it the strongest security guarantee.
BCH and BSV operate with significantly less hash power, making them theoretically more vulnerable to 51% attacks, though no successful attack has disrupted either network to date.
How Do Their Use Cases Differ?
Each variant has evolved toward a distinct market position. Bitcoin's trajectory points toward digital gold: a store of value, portfolio hedge, and reserve asset.
Institutional adoption through spot ETFs, corporate treasury holdings, and sovereign reserve discussions all reinforce this narrative. Everyday payments happen on Layer 2, while the base layer prioritises security and settlement finality.
Bitcoin Cash occupies the digital cash lane. Its low fees and fast confirmations make it functional for point of sale payments, remittances, and tipping.
Several payment processors and merchant platforms accept BCH, and its community emphasises real world usability over speculative value storage.
Bitcoin SV targets enterprise and data applications. Beyond payments, the network is designed to store data records, supply chain logs, and tokenised assets directly on chain.
Its vision extends beyond currency into a general purpose data infrastructure layer, though adoption in this segment remains limited compared to its ambitions, and reduced exchange access has constrained its market reach.
BTC vs BCH vs BSV Price and Market Position
The market has delivered a clear verdict on relative value. Bitcoin trades in the range of $63,000 to $64,000 at time of writing, with a market cap exceeding $1.2 trillion. It is the undisputed market leader and the benchmark against which all other cryptocurrencies are measured.
Bitcoin Cash trades around $200, with a market cap of approximately $4 billion. It maintains a position in the top 25 cryptocurrencies by market cap and carries consistent exchange liquidity across all major platforms.
Bitcoin SV trades around $14 to $15, with a market cap of approximately $290 million. It has been delisted from several major exchanges over the years and carries significantly lower liquidity and trading volume than either BTC or BCH.
The price gap between the three tells the story of market confidence. BTC commands a roughly 300x premium over BCH and a roughly 4,000x premium over BSV.
BTC and BCH are both available for trading on Bitrue alongside a broad selection of digital assets and traditional finance instruments through a single regulated platform.
Conclusion
Bitcoin, Bitcoin Cash, and Bitcoin SV represent three different answers to the same question: how should a decentralised digital currency scale? Bitcoin chose conservative base layer design with Layer 2 innovation. Bitcoin Cash chose bigger blocks for direct onchain payments.
Bitcoin SV chose unbounded blocks for enterprise scale data. The market has favoured Bitcoin's approach by an overwhelming margin, but each variant continues to operate with its own community, development roadmap, and vision for the future of peer to peer digital value.
