The world of cryptocurrency has evolved dramatically since Bitcoin’s inception in 2009. One of the most fascinating developments in this space is the emergence of Bitcoin forks—alternative versions of the original blockchain that arise from protocol disagreements or innovation attempts. While there have been nearly 100 Bitcoin fork projects since 2008, around 70 remain active today. These forked cryptocurrencies offer unique features, from increased block sizes to enhanced privacy and new consensus mechanisms.
In this guide, we’ll explore some of the most notable Bitcoin fork coins, including their technical foundations, market performance, and ongoing challenges. Whether you're a long-time crypto enthusiast or new to digital assets, understanding these forks can deepen your knowledge of blockchain evolution and help inform smarter investment decisions.
What Are Bitcoin Forks?
A Bitcoin fork occurs when a blockchain splits into two separate chains due to changes in its underlying protocol. This can happen for various reasons: improving scalability, introducing new features, or resolving community disputes. There are two main types:
- Soft forks: Backward-compatible upgrades.
- Hard forks: Permanent divergences requiring all nodes to upgrade.
Hard forks often result in a new cryptocurrency being distributed to existing BTC holders—commonly referred to as an "airdrop" or "forked coin."
Key Bitcoin Fork Coins in 2025
Bitcoin Cash (BCH)
Bitcoin Cash (BCH) emerged on August 1, 2017, at block height 478,559, making it the first major hard fork of Bitcoin. Designed as a scalability solution, BCH increased the block size limit from 1MB to 8MB (later expanded further), enabling faster and cheaper transactions.
Unlike Bitcoin, BCH does not support Segregated Witness (SegWit), as developers believed large blocks made it unnecessary. The mining algorithm remains SHA-256, meaning ASIC miners and mining pools used for BTC can also mine BCH. Some pools even offer automatic BTC/BCH switching based on profitability, enhancing miner flexibility.
Development is supported by multiple teams, including Bitcoin ABC and Bitcoin Unlimited, promoting decentralization of control.
Market Insight: BCH reached an all-time high of $4,070 but currently trades around $289. Despite controversy over whether it represents “true Bitcoin,” it remains one of the most recognized Bitcoin alternatives.
While BCH enjoys broader adoption than many other forks, its post-fork security remains a concern. Splitting hash power reduces overall network strength, increasing vulnerability to attacks like 51% takeovers.
Bitcoin Gold (BTG)
Bitcoin Gold (BTG) launched with a different mission: democratizing mining. By changing the proof-of-work algorithm to Equihash, BTG shifted from ASIC-dominated mining to GPU-based mining, aiming to prevent centralization by large mining farms.
It retained Bitcoin’s 1MB block size and added SegWit support but introduced Emergency Difficulty Adjustment (EDA) to stabilize mining during fluctuating hash rates.
Price Movement: BTG peaked near $500 shortly after launch but now trades at approximately $27.70.
Despite its egalitarian ideals, BTG faces criticism over technical shortcomings. It lacks robust replay attack protection and has not undergone comprehensive code audits. Additionally, community trust has waned due to inconsistent development and unresolved security concerns.

Lightning Bitcoin (LBTC)
Lightning Bitcoin (LBTC) forked at block height 499,999 and stands out for adopting Delegated Proof-of-Stake (DPoS) instead of traditional Proof-of-Work (PoW). Inspired by EOS, LBTC uses 101 elected super nodes to validate transactions—significantly boosting speed and efficiency.
This shift allows LBTC to process thousands of transactions per second while separating voting rights from block production. If a node behaves maliciously, it can be voted out quickly, reducing risks associated with centralized mining power.
Market Performance: LBTC once hit $1,259 but now trades around $3.20—a stark decline reflecting low adoption and limited ecosystem growth.
The primary risk for LBTC lies in code reliability. Any critical bug could destabilize the network, especially given its smaller developer base and community engagement compared to larger projects.
Bitcoin Private (BTCP)
Bitcoin Private (BTCP) resulted from a merged fork between Bitcoin and ZClassic (ZCL) in March 2018. It introduced zk-SNARKs, a zero-knowledge proof technology originally developed by Zcash, offering strong transaction privacy.
Users who held BTC or ZCL at the time received BTCP at a 1:1 ratio per coin—meaning someone with 10 BTC and 10 ZCL would receive 20 BTCP.
Privacy Advantage: BTCP is considered one of the most private Bitcoin-derived coins, combining BTC’s brand recognition with advanced anonymity features.
However, governance issues have plagued BTCP. Core developer Reid Chilton accused fellow team members of misappropriating funds, leading to his removal. Today, two competing Telegram groups circulate conflicting updates, creating confusion among users and eroding trust.
This fragmentation highlights the importance of transparent leadership and unified communication in decentralized projects.
Super Bitcoin (SBTC)
Super Bitcoin (SBTC) forked at block 498,888 in December 2017 with ambitions far beyond simple scaling. Led by prominent figure Li Xiaolai—often dubbed “China’s Bitcoin billionaire”—SBTC aimed to integrate advanced technologies like smart contracts, the Lightning Network, and zero-knowledge proofs.
With an 8MB block size and a total supply of 21.21 million coins (210,000 more than BTC), SBTC allocated the extra coins through a pre-mine managed by a foundation for ecosystem development and early contributor incentives.
Market Trajectory: SBTC once reached $1,526 but now trades near $3.20.
The pre-mined allocation remains controversial. Critics argue it undermines decentralization and could enable insider profiteering, despite claims that funds are used for public benefit.
Frequently Asked Questions (FAQ)
What is a Bitcoin fork?
A Bitcoin fork is a split in the blockchain caused by changes in the network’s protocol. It results in two separate chains—one following the old rules and one under new ones—often creating a new cryptocurrency distributed to existing BTC holders.
Which Bitcoin fork is the most successful?
Bitcoin Cash (BCH) is widely regarded as the most successful fork due to its high visibility, exchange listings, merchant adoption, and sustained development efforts compared to other spin-offs.
Why do Bitcoin forks lose value after launch?
Many forks experience initial hype followed by rapid sell-offs ("dumping") as recipients treat them as free money. Without strong use cases or active development, prices tend to decline over time.
Can I still claim coins from past Bitcoin forks?
Most major forks occurred between 2017–2018. If you held BTC during those events and used a self-custody wallet (not an exchange), you might still be able to claim forked coins—but doing so carries security risks if private keys are exposed.
Are Bitcoin forks safe to invest in?
Forks vary greatly in legitimacy and longevity. Projects with transparent teams, audited code, and real-world utility pose lower risks. However, many forks lack long-term vision and suffer from poor governance—exercise caution.
How do I tell if a fork is legitimate?
Look for clear documentation, open-source code repositories (e.g., GitHub), community discussion forums, and announcements from reputable wallets or exchanges supporting the fork.
