Cryptocurrencies have evolved significantly since the inception of Bitcoin (BTC), with numerous forks creating new digital assets that aim to improve or reinterpret the original vision. Among the most notable are Bitcoin Cash (BCH) and Bitcoin SV (BSV)—both born from contentious hard forks of the Bitcoin network. While they share a common origin, each blockchain has taken a distinct path in terms of design philosophy, technical specifications, and community goals. This article explores the core differences between BTC, BCH, and BSV, helping you understand their unique characteristics and long-term implications.
The Origins of BTC, BCH, and BSV
Bitcoin (BTC): The Original Blockchain
Bitcoin, launched in 2009 by the pseudonymous Satoshi Nakamoto, is the first decentralized cryptocurrency. Its blockchain began with the genesis block on January 3, 2009, marking the start of a peer-to-peer electronic cash system.
Initially, miners received 50 BTC as a block reward. This reward halves approximately every four years—or after every 210,000 blocks—in an event known as the "halving." As of now, the network generates a new block roughly every ten minutes, with a hard cap of 21 million BTC in total supply.
Based on the current issuance rate, all bitcoins are projected to be mined by around 2140, making BTC a deflationary asset by design. Over time, BTC has evolved from a niche digital currency into a global store of value—often referred to as "digital gold."
Despite its success, BTC has faced criticism for scalability issues due to its 1MB block size limit, which can lead to slow transaction times and high fees during peak usage. These limitations sparked debates within the community about how best to scale the network—leading to major forks.

Bitcoin Cash (BCH): Scaling Through Larger Blocks
On August 1, 2017, at block height #478558, a group of developers and mining companies—including Bitmain—initiated a hard fork from the Bitcoin blockchain, resulting in Bitcoin Cash (BCH).
The primary motivation behind the split was to address BTC’s scalability challenges. The BCH team believed that increasing the block size was the most effective way to enable faster and cheaper transactions for everyday use.
- Initial block size: Increased from 1MB to 8MB
- Later upgraded to 32MB in May 2018
- Goal: Restore BTC’s original purpose as peer-to-peer electronic cash
By allowing more transactions per block, BCH aimed to reduce congestion and maintain low fees—even during periods of high demand.
However, the BCH ecosystem wasn’t without conflict. In November 2018, another hard fork occurred, splitting BCH into two chains: BCHABC (later renamed BCH) and BCHSV (which became BSV). This division stemmed from disagreements over future development direction—particularly regarding smart contract functionality and block size expansion.
Ultimately, BCH retained broader community support and continued evolving with a focus on usability and fast payments.
Bitcoin SV (BSV): Returning to “Original Bitcoin”
Bitcoin SV (Satoshi Vision) emerged on October 24, 2017, at block height #491407, following a contentious split from the BCH blockchain. Led by figures such as Craig Wright and Calvin Ayre, the BSV movement aimed to return to what they believed was Satoshi Nakamoto’s original blueprint for Bitcoin.
Key principles of BSV include:
- Unlimited block sizes (theoretically scalable to 128MB+ and beyond)
- Emphasis on data storage and enterprise applications
- Rejection of modern scaling solutions like SegWit and Lightning Network
- Advocacy for restoring GPU mining viability to decentralize mining power
The developers argued that large blocks would allow Bitcoin to handle massive transaction volumes while supporting complex data transactions—effectively turning the blockchain into a global data ledger.
Shortly after launch, the BSV team distributed 100,000 BSV tokens, with 95% allocated to ecosystem development and promotion. However, BSV faced controversy when it experienced a 51% attack in 2018—where malicious actors gained control of over half the network's hashing power—leading to double-spending incidents and significant financial losses.
Despite criticism from parts of the crypto community, BSV continues to operate with ambitions of becoming a scalable platform for enterprise-level blockchain applications.

Comparative Overview: BTC vs. BCH vs. BSV
| Feature | BTC | BCH | BSV |
|---|---|---|---|
| Launch Date | Jan 2009 | Aug 2017 | Oct 2017 |
| Block Size | 1MB (with SegWit ~4MB) | Up to 32MB | Dynamically scalable (up to 128MB+) |
| Primary Goal | Store of value | Peer-to-peer cash | Enterprise data ledger |
| Transaction Speed | Moderate (higher fees during congestion) | Fast and low-cost | Very fast with minimal fees |
| Consensus Mechanism | Proof of Work (PoW) | PoW | PoW (slightly modified algorithm) |
| Total Supply Cap | 21 million | 21 million | 21 million |
While all three share the same maximum supply limit, their approaches to achieving utility differ significantly.
BTC prioritizes security and decentralization, often at the expense of speed and cost-efficiency. BCH focuses on being a usable digital currency for daily transactions. BSV pushes the boundaries of scalability, aiming to serve not just payments but also data-heavy applications like record-keeping and microtransactions.
Frequently Asked Questions (FAQs)
Q: What caused the split between BTC and BCH?
A: The main cause was disagreement over how to scale Bitcoin. BTC developers favored off-chain solutions like the Lightning Network, while BCH supporters advocated for larger blocks to increase on-chain capacity directly.
Q: Is BSV considered part of the original Bitcoin vision?
A: Proponents of BSV claim it follows Satoshi Nakamoto’s original whitepaper more closely due to its emphasis on large blocks and on-chain scaling. However, many in the broader crypto community remain skeptical of this claim.
Q: Can I use BCH or BSV for everyday purchases?
A: Yes—both BCH and BSV are accepted by some merchants globally, particularly online retailers and service providers focused on crypto adoption. However, BTC remains the most widely accepted.
Q: Are these coins mined the same way?
A: All three use Proof of Work (PoW), but BSV uses a slightly modified version of SHA-256 designed to resist certain ASIC optimizations. In practice, though, ASIC miners dominate all three networks.
Q: Which one has the highest market value?
A: BTC has the largest market capitalization by far. Among the forks, BCH typically holds a higher valuation than BSV, reflecting broader investor confidence and exchange listings.
Q: Could there be more forks in the future?
A: Hard forks are possible whenever there's deep disagreement within a community. While no major splits are currently imminent for these chains, ideological differences continue to shape their evolution.
Final Thoughts
BTC, BCH, and BSV represent different interpretations of what Bitcoin can be:
- BTC as digital gold—a secure, scarce asset
- BCH as electronic cash—fast and affordable for daily use
- BSV as a scalable data platform—aiming for enterprise adoption
Each chain reflects a unique vision shaped by technical choices and philosophical beliefs. Understanding their differences helps investors and users make informed decisions based on use cases, risk tolerance, and long-term outlook.
Whether you're drawn to BTC’s stability, BCH’s usability, or BSV’s ambitious scalability goals, one thing is clear: the legacy of Bitcoin continues to inspire innovation across multiple fronts.
