The world of cryptocurrency has evolved significantly since Bitcoin (BTC) first emerged in 2009. As the pioneer digital currency, BTC laid the foundation for a decentralized financial future. However, over time, disagreements within the community over scalability, block size, and development direction led to several high-profile forks—resulting in new cryptocurrencies like Bitcoin Cash (BCH) and Bitcoin SV (BSV). While all three share common roots, they differ in technical design, philosophy, and long-term vision.
This article explores the core distinctions between BTC, BCH, and BSV, helping you understand their unique characteristics, historical context, and practical implications for users and investors.
The Origins of Bitcoin and Its Major Forks
Bitcoin (BTC) was launched in 2009 with a 1MB block size limit designed to ensure network security and decentralization. As transaction volume grew, this limit caused congestion and higher fees—sparking debate about how best to scale the network.
These debates eventually led to hard forks: permanent changes to the blockchain’s protocol that create a new, separate chain. Two of the most notable outcomes are Bitcoin Cash (BCH) and Bitcoin SV (BSV).

Bitcoin (BTC): The Original Digital Currency
BTC runs on the original blockchain, with its genesis block mined on January 3, 2009. It operates under strict protocol rules:
- Block time: Approximately 10 minutes
- Block size: Effectively limited by consensus (originally 1MB, later enhanced via SegWit)
- Supply cap: 21 million coins
- Mining reward: Starts at 50 BTC per block; halves every 210,000 blocks (~4 years)
This halving mechanism ensures scarcity and controlled issuance. At the current rate, the final BTC is expected to be mined around the year 2140.
BTC prioritizes security and decentralization over raw transaction throughput. To address scalability, it adopted solutions like the Lightning Network—an off-chain layer for fast, low-cost payments.
Despite its limitations in transaction speed, BTC remains the most widely adopted and valuable cryptocurrency, often referred to as "digital gold."
Bitcoin Cash (BCH): Scaling On-Chain Transactions
In August 2017, a faction of developers and miners initiated a hard fork at block height #478558, creating Bitcoin Cash (BCH). Their primary motivation? To return to what they saw as Satoshi Nakamoto’s original vision of peer-to-peer electronic cash—capable of handling everyday transactions without delays or high fees.
Key features of BCH include:
- Larger block sizes: Initially increased to 8MB, later raised to 32MB
- On-chain scaling: Emphasis on increasing block capacity rather than relying on second-layer solutions
- No SegWit: BCH rejected Segregated Witness, believing it introduced complexity without sufficient benefit
By expanding block size, BCH allows more transactions per block, reducing fees and confirmation times during peak usage.
However, BCH itself underwent another split in November 2018, dividing into BCHABC (later simply BCH) and BSV, due to disagreements over future development paths.
Bitcoin SV (BSV): Restoring the Original Protocol
Bitcoin SV—where “SV” stands for Satoshi Vision—emerged from a hard fork of BCH on November 15, 2018 (not October 2017 as sometimes misreported), at block height #556767. Led by Craig Wright and supported by CoinGeek and other entities, BSV aimed to restore what its proponents believe is the true Bitcoin protocol as envisioned by Satoshi Nakamoto.
BSV's core principles include:
- Massive block sizes: Blocks can scale up to 128MB or more, enabling high-throughput applications
- Stable protocol: Minimal changes to the original codebase to ensure predictability for enterprise use
- Enterprise focus: Designed for businesses needing reliable, scalable blockchain infrastructure
After the fork, the BSV team released 100,000 BSV tokens, with 95% allocated to ecosystem development and support.
While BSV shares BTC’s proof-of-work consensus model, it uses slightly modified algorithms optimized for large-scale mining operations. However, centralization concerns have arisen due to a small number of mining pools controlling most of the hash rate.
In 2019, BSV faced criticism when it experienced a double-spend attack—where attackers exploited low network difficulty to reverse transactions—resulting in financial losses and damaged credibility.

Comparative Overview: BTC vs. BCH vs. BSV
| Feature | BTC | BCH | BSV |
|---|---|---|---|
| Launch Date | 2009 | August 1, 2017 | November 15, 2018 |
| Block Size | ~1–4 MB (with SegWit) | Up to 32 MB | Up to 128+ MB |
| Transaction Speed | Slower during congestion | Faster than BTC | Very fast |
| Fees | Higher during peak times | Lower than BTC | Typically lowest |
| Development Focus | Security & decentralization | Peer-to-peer cash | Enterprise scalability |
| Consensus Mechanism | Proof-of-Work | Proof-of-Work | Proof-of-Work |
While all three use proof-of-work mining, their differing philosophies shape how they're used:
- BTC is primarily seen as a store of value.
- BCH positions itself as digital money for daily transactions.
- BSV targets developers and enterprises building on blockchain.
Frequently Asked Questions (FAQ)
Q: What caused the split between BTC and BCH?
A: The main issue was scalability. BTC maintained a small block size to preserve decentralization, while BCH supporters wanted larger blocks to allow more transactions on-chain and lower fees.
Q: Is BSV the same as BTC?
A: No. While BSV claims to follow Satoshi’s original blueprint, it is a separate blockchain with different rules, governance, and technical specifications.
Q: Which is better for sending money quickly?
A: BCH and BSV generally offer faster confirmations and lower fees than BTC during high traffic periods due to larger block sizes.
Q: Can I mine all three cryptocurrencies?
A: Yes, but they require different equipment setups. BTC and BCH use similar hashing algorithms (SHA-256), so miners can switch between them. BSV also uses SHA-256 but has less mining competition.
Q: Are any of these coins at risk of disappearing?
A: While market dynamics change, BTC remains dominant. BCH and BSV have smaller communities but continue active development. Long-term survival depends on adoption and utility.
Q: Why did BSV suffer a double-spend attack?
A: Due to a drop in network hash rate, attackers were able to gain majority control temporarily and rewrite parts of the blockchain—highlighting risks associated with lower mining decentralization.

Final Thoughts
BTC, BCH, and BSV each represent different visions of what blockchain technology should become. BTC emphasizes security and scarcity. BCH focuses on usability as digital cash. BSV aims for massive scalability for commercial applications.
Understanding these differences helps investors make informed decisions based on their goals—whether that’s holding long-term value, making frequent payments, or exploring enterprise blockchain opportunities.
As the crypto space continues to evolve, staying informed about protocol changes, community sentiment, and technological advancements will remain crucial for navigating this dynamic landscape.
