Bitcoin Cash (BCH) emerged in 2017 as a notable fork from Bitcoin. Initially sharing the same blockchain and data, BCH began operating independently post-fork, following a distinct development path. This article explores its origins, features, and market behavior.
The Origins of Bitcoin Cash
The creation of Bitcoin Cash stems from the long-standing scalability debate within the Bitcoin community. By 2016, rising cryptocurrency adoption led to increased transaction volume on the Bitcoin network. This surge resulted in significant congestion, higher fees, and delayed processing times, sometimes stretching to several days.
Two primary solutions were proposed:
- Increasing the block size to allow more transactions per block.
- Implementing off-chain solutions like the Lightning Network and Segregated Witness (SegWit).
The first approach aimed to expand capacity directly, akin to adding lanes to a highway. The second focused on efficiency improvements through layer-two technologies.
The Birth of Bitcoin Cash
Unable to reach consensus, the Bitcoin community split. On August 1, 2017, a team supported by major mining players like Bitmain mined the first block of a new chain. This event marked the birth of Bitcoin Cash.
BCH increased the block size to 8MB, enabling it to handle over eight times more transactions than Bitcoin. It also opted not to support SegWit. Since the split, the two chains have evolved separately, with different development teams and roadmaps.
How Bitcoin Cash Differs from Bitcoin
While sharing Bitcoin's core principles—such as a Proof-of-Work consensus mechanism, a 21 million coin supply cap, and halving events—BCH introduced several key changes:
- Block Size: BCH uses an 8MB block size, compared to Bitcoin's 1MB, allowing for greater throughput.
- Difficulty Adjustment: BCH employs a dynamic difficulty adjustment algorithm to stabilize block times, regardless of network participation.
- Community Adoption: Bitcoin maintains broader global recognition and institutional investment, whereas BCH has a smaller, though dedicated, community.
Market Performance and Volatility
Following its launch, BCH's price surged from around $500 to nearly $4,100 during the late 2017 bull market. Its market capitalization briefly reached 20% of Bitcoin's. However, the subsequent bear market hit BCH harder; it fell over 55 times from its peak, while Bitcoin declined by less than 6 times. This illustrates BCH's higher volatility.
BCH also played a pivotal role in the 2020 halving cycle, rallying 182% in 58 days and igniting bullish momentum across the market.
The 2020 Fork and Bitcoin SV
In 2018, another significant fork occurred, leading to the creation of Bitcoin SV (BSV). This version increased the block size limit to 128MB. Both BCH and BSV have maintained positions in the top cryptocurrencies by market cap.
Recent Developments: The 2024 BCH Fork
The BCH network has announced another upgrade scheduled for November 2024. This update aims to integrate InterPlanetary File System (IPFS) compatibility and introduce a new coinbase rule that allocates 8% of block rewards to a development fund.
Community Response and Concerns
This proposal has sparked debate. Some community members view the reward allocation as a reduction in miner income. Developers argue it is necessary for sustainable funding and ongoing project maintenance.
Implications for Users
Major cryptocurrency exchanges have announced support for the fork. Users holding BCH at the time of the snapshot will receive new forked tokens, similar to an airdrop.
To avoid complications, it is advised not to transfer BCH on or near the snapshot date, as many platforms will suspend deposits and withdrawals during that period.
A Word of Caution
While forks can bring new opportunities, they also carry risks. The long-term viability of a new chain depends on community support, development activity, and market adoption. Participants should carefully evaluate these factors before making decisions.

Frequently Asked Questions
What is a blockchain fork?
A fork occurs when a blockchain splits into two separate paths due to a change in protocol or a disagreement among participants. It can result in two versions of the blockchain with shared transaction history up to the split point.
How can I receive forked tokens from the BCH upgrade?
If you hold BCH in a supported exchange or non-custodial wallet at the time of the snapshot, you will automatically receive the new tokens. No additional action is typically required.
Is Bitcoin Cash more scalable than Bitcoin?
Due to its larger block size, Bitcoin Cash can process more transactions per second on-chain. However, Bitcoin uses layered solutions like the Lightning Network to achieve scalability, leading to different philosophical approaches.
What are the risks of investing in a forked asset?
New forked assets often face volatility, uncertain development futures, and lower liquidity. There is also a risk of chain instability or reduced security if miner support declines.
Will the new BCH fork have value?
The value of a new forked token is determined by market demand, utility, and community support. It is not guaranteed and can be highly speculative.
Where can I safely store BCH during a fork?
Using a major, supportive exchange that has announced snapshot support is often safest for users seeking to claim forked tokens. Alternatively, ensure your private wallet is compatible and secure.
