What is Bitcoin Cash?

Bitcoin Cash (BCH) is a cryptocurrency that was created in August 2017 as a fork of Bitcoin. A fork happens when a blockchain splits into two separate chains, often due to disagreements among developers and miners. Bitcoin Cash was designed to process more transactions per second than Bitcoin, aiming to be a practical digital cash for everyday payments.

As of September 29, 2026, Bitcoin Cash has a market capitalization rank of 18, with a circulating supply of 20,096,069 BCH. Its market cap rank indicates it is among the larger cryptocurrencies by total value, though it is much smaller than Bitcoin.

How Bitcoin Cash Works

Bitcoin Cash operates on a blockchain, which is a public ledger of all transactions. Like Bitcoin, it uses a proof-of-work consensus mechanism, where miners compete to add new blocks of transactions to the chain. Miners are rewarded with newly issued BCH and transaction fees.

The key difference between Bitcoin Cash and Bitcoin is the block size limit. Bitcoin has a block size limit of 1 megabyte (MB), while Bitcoin Cash increased it to 8 MB at launch and later to 32 MB. A larger block size allows more transactions to be included in each block, which can increase the network’s transaction throughput and reduce fees during periods of high demand.

Bitcoin Cash also made other technical changes, such as not adopting the Segregated Witness (SegWit) upgrade and enabling a different difficulty adjustment algorithm to respond faster to changes in mining power. These changes were intended to make BCH more suitable for fast, low-cost payments.

What is BCH Used For?

BCH is primarily used as a medium of exchange. It can be sent and received peer-to-peer without intermediaries, often with lower fees than Bitcoin. Common uses include:

• Payments: Some merchants accept BCH for goods and services, both online and in physical stores.
• Remittances: People use BCH to send money across borders quickly and cheaply compared to traditional remittance services.
• Store of value: Like other cryptocurrencies, some holders treat BCH as an investment, though its price is volatile.
• Microtransactions: The low fees make BCH suitable for small transactions, such as tipping online content creators.

BCH can be stored in various wallets, including software wallets, hardware wallets, and online exchanges. It can be bought or sold on many cryptocurrency exchanges.

Notable History

The creation of Bitcoin Cash was the result of a long-standing debate within the Bitcoin community about how to scale the network. Some believed that increasing the block size was the best way to handle more transactions, while others favored off-chain solutions like the Lightning Network. When no consensus was reached, a group of developers and miners initiated a hard fork on August 1, 2017, creating Bitcoin Cash.

Since then, Bitcoin Cash has undergone several upgrades, including increases in block size and improvements to its difficulty adjustment. In November 2018, a contentious hard fork split Bitcoin Cash into two chains: Bitcoin Cash ABC (now simply Bitcoin Cash) and Bitcoin SV (BSV). This split further divided the community.

Over the years, Bitcoin Cash has faced challenges in gaining widespread adoption. While it has a dedicated community and is accepted by some merchants, it has not reached the level of usage or recognition of Bitcoin.

Risks and Criticisms

Bitcoin Cash faces several risks and criticisms:

• Centralization: Larger blocks can lead to fewer nodes being able to store the full blockchain, potentially making the network more centralized among a small number of large miners.
• Security: A smaller network hashrate compared to Bitcoin makes BCH more vulnerable to 51% attacks, where a group of miners could control the network.
• Adoption: Despite its focus on payments, BCH has not achieved widespread merchant adoption, and its use in commerce remains limited.
• Competition: BCH competes with many other cryptocurrencies that offer fast and cheap transactions, including Litecoin, Dash, and stablecoins.
• Price volatility: Like all cryptocurrencies, BCH’s price can be highly volatile, which makes it less ideal as a stable unit of account.

How Bitcoin Cash Compares to Alternatives

Bitcoin Cash is often compared to Bitcoin and other payment-focused cryptocurrencies. Here is a comparison table:

Feature	Bitcoin (BTC)	Bitcoin Cash (BCH)	Litecoin (LTC)
Block size limit	1 MB (with SegWit)	32 MB	1 MB (with SegWit)
Average block time	10 minutes	10 minutes	2.5 minutes
Primary focus	Store of value	Payments	Payments
Consensus	Proof of Work	Proof of Work	Proof of Work
Market cap rank (as of Sep 29, 2026)	1	18	Not provided

Bitcoin Cash differentiates itself from Bitcoin by prioritizing on-chain scalability for payments. However, Bitcoin remains the dominant cryptocurrency by market cap and adoption. Litecoin, another early altcoin derived from Bitcoin's codebase, also focuses on faster transactions but with a different technical approach.

Other alternatives include stablecoins like Tether (USDT) and USD Coin (USDC), which are pegged to fiat currencies and offer price stability, making them popular for payments and transfers. However, stablecoins rely on centralized issuers and are not decentralized like BCH.

Conclusion

Bitcoin Cash is a cryptocurrency that emerged from a desire to make Bitcoin more suitable for everyday payments. It offers faster and cheaper transactions than Bitcoin by using larger blocks, but it faces challenges in adoption, centralization, and competition. As of September 29, 2026, it holds a market cap rank of 18, indicating it is a significant but not leading cryptocurrency. Whether BCH achieves its goal of becoming a widely used digital cash remains to be seen.
