BITCOIN CASH VS BITCOIN: KEY DIFFERENCES EXPLAINED
Understand the main differences between Bitcoin and Bitcoin Cash, including speed, scalability, and usage.
Bitcoin Cash (BCH) is a decentralised digital currency that emerged from a hard fork of Bitcoin (BTC) on 1 August 2017. The fork was the result of ongoing debates within the Bitcoin community over how to scale the network and increase transaction throughput. Bitcoin Cash was designed to be a peer-to-peer electronic cash system with faster and cheaper transactions in comparison to Bitcoin.
Following the original vision laid out in the Bitcoin whitepaper by Satoshi Nakamoto, Bitcoin Cash aims to serve everyday buyers and sellers, rather than acting solely as a store of value. It maintains Bitcoin’s fundamental principles such as decentralisation and cryptographic security while implementing key changes to overcome limitations faced by Bitcoin.
The primary distinction between Bitcoin Cash and Bitcoin is the block size. Bitcoin Cash increased the block size from 1MB (as used by Bitcoin in 2017) to 8MB initially, and later to 32MB, allowing more transactions to be included per block. This helps reduce transaction delays and fees – issues that had become more pronounced on the Bitcoin network as adoption grew.
Like Bitcoin, Bitcoin Cash uses the Proof-of-Work (PoW) consensus mechanism, where miners solve complex cryptographic puzzles to validate transactions and secure the network. It has a capped supply of 21 million coins, mirroring the scarcity model of Bitcoin.
Due to the shared history, both Bitcoin and Bitcoin Cash have many similarities at the protocol level, but diverge significantly in their strategic direction, scaling ideologies, and intended use cases.
In the years following the hard fork, Bitcoin Cash has seen varying levels of adoption, particularly among users prioritising fast, low-cost transactions. The network has also undergone its own forks, including splits between Bitcoin Cash ABC and Bitcoin SV (Satoshi’s Vision), reflecting continued debates over its future development.
Despite speculation and fluctuating market performance, Bitcoin Cash remains an active Top 30 cryptocurrency by market capitalisation and retains a loyal community of developers, miners, merchants, and users championing on-chain scalability in line with its founding goals.
Bitcoin (BTC) and Bitcoin Cash (BCH) share a common origin but differ significantly in several technical and functional aspects. Understanding these differences is crucial for anyone considering usage, investment, or involvement in either cryptocurrency.
1. Block Size and Scalability
One of the most significant differences between Bitcoin and Bitcoin Cash is block size. When Bitcoin Cash forked in 2017, it increased the block size limit from 1MB to 8MB. As of now, Bitcoin Cash supports up to 32MB blocks. This increase enables BCH to process more transactions per block, resulting in faster confirmations and lower fees.
Bitcoin, on the other hand, has kept its block size relatively small (around 1-2MB) but introduced Segregated Witness (SegWit) and the Lightning Network as off-chain scaling solutions. While BCH focuses on on-chain scalability through larger blocks, BTC seeks to scale via second-layer protocols.
2. Transaction Speed and Fees
Larger blocks on the BCH network mean more transactions can be confirmed in each block. This typically results in faster transactions and minimal fees, often less than a cent. Bitcoin transactions can become congested, especially during peak periods, leading to higher fees and longer confirmation times.
For users prioritising quick and inexpensive transfers, such as peer-to-peer payments or remittances, Bitcoin Cash offers a practical advantage. Bitcoin, in contrast, has evolved to function more as a digital store of value or “digital gold,” which doesn’t necessitate high transaction throughput.
3. Philosophy and Community
The philosophical divergence between the two communities also drives development. Bitcoin’s focus is largely on security, reliability, and maintaining a robust investment-grade asset. Its development is conservative and cautious, often opting for incremental improvements.
Bitcoin Cash places greater emphasis on usability for everyday payments. Proponents argue that the original intent of Bitcoin was to serve as electronic cash and that increasing transaction capacity directly on-chain is the best way to stay true to that vision.
4. Development Approach
Bitcoin’s development is subject to rigorous peer review and coordination via Bitcoin Core, its dominant developer group. BCH development is more fragmented but decentralised, with contributions from groups such as Bitcoin ABC and Bitcoin Unlimited. This leads to more frequent protocol changes and upgrades in BCH, though sometimes at the cost of cohesion.
5. Hash Rate and Security
Due to its higher market value and larger miner community, Bitcoin enjoys significantly more hashing power, making its network more secure against attacks. Bitcoin Cash has a lower hash rate, but still enough to ensure general security on its network. However, its lower hash rate has made Bitcoin Cash more susceptible to reorganisation attacks in theory, especially during periods of low mining activity.
6. Market Perception and Adoption
Market perception plays a large role. Bitcoin is widely considered the flagship cryptocurrency, and its limited supply and longer track record contribute to its “digital gold” image. Institutional investors, regulators, and exchanges largely focus on BTC over BCH.
Bitcoin Cash is often supported by platforms favouring faster retail transactions, including some point-of-sale systems and merchant platforms. While its market capitalisation and visibility may be lower, it serves a defined niche of the cryptocurrency market effectively.
Both Bitcoin and Bitcoin Cash have carved out distinct roles in the cryptocurrency ecosystem, reflecting their differing technological choices and adoption strategies. Understanding the respective use cases of each can help inform investment, development, or payment decisions.
Use Cases for Bitcoin (BTC)
- Store of Value: Bitcoin is often compared to gold, finding use primarily as a long-term investment vehicle. Many investors hold BTC as a hedge against inflation and as a non-sovereign asset.
- Institutional Investment: BTC is favored by large funds, publicly-traded companies, and institutional platforms due to its liquidity, regulatory clarity, and established market presence.
- Digital Hedge Asset: Bitcoin's decentralised nature appeals to those seeking alternatives to fiat currencies, especially in uncertain economic climates.
Use Cases for Bitcoin Cash (BCH)
- Everyday Payments: With its emphasis on quick, low-cost transactions, BCH is well suited to small, frequent payments. Merchants and users in regions with high remittance needs have taken particular interest in BCH.
- Point-of-Sale Systems: Various service providers support Bitcoin Cash for retail transactions, including QR code payments in physical stores and e-commerce integrations.
- Unbanked Regions: BCH has adoption in areas where traditional banking access is limited. Its ability to process payments cheaply without intermediaries is an attractive feature in underserved economies.
Future Outlook
Bitcoin is likely to maintain its dominance as a store of value and an institutional asset. Ongoing upgrades like Taproot, second-layer adoption with the Lightning Network, and increasing institutional inflows continue to bolster its long-term trajectory.
Bitcoin Cash, while no longer among the top five cryptocurrencies by market cap, retains strong grassroots support and adoption in niche areas. It may continue to grow in regions where transaction affordability is a priority. Its future will depend on continued development, community consensus, and real-world merchant adoption.
In summary, Bitcoin and Bitcoin Cash are not in direct competition but rather serve complementary roles. BTC acts as a robust digital asset for saving and institutional allocation, while BCH shines in everyday commerce and low-fee use cases. Choosing between them depends on the specific needs and preferences of users and investors alike.
