Bitcoin Cash (BCH) is a cryptocurrency created in 2017 as a result of a hard fork from the original Bitcoin blockchain. A hard fork represents a significant change in a network’s protocol, splitting the blockchain into two incompatible paths and requiring users and nodes to upgrade to the latest software version. BCH was developed to address growing concerns around Bitcoin’s transaction fees and confirmation times, with the goal of reinstating a decentralized and efficient peer-to-peer payment system.
As a faster and more affordable payment network, Bitcoin Cash aims to fulfill Satoshi Nakamoto’s original vision of electronic cash without relying on financial intermediaries. With transaction fees often below $0.01 and confirmations taking just seconds, BCH offers a practical alternative to Bitcoin, which is often treated more as a store of value than a medium for daily transactions.
An active community of developers and supporters maintains Bitcoin Cash, believing it serves as a necessary and viable alternative to Bitcoin. The network is powered by Bitcoin Cash nodes, which form a distributed ecosystem that validates transactions and secures the blockchain.
Understanding Bitcoin Cash (BCH)
Bitcoin Cash emerged in 2017 in response to increasing dissatisfaction with the Bitcoin network’s scalability. Between 2009 and 2016, transaction fees rose significantly, peaking at $54.64 in December 2017. These issues were largely due to Bitcoin’s 1 MB block size limit, which restricted the number of transactions processed per block and led to network congestion.
BCH was designed to tackle scalability by increasing the block size, allowing more transactions per block and reducing fees. However, not all developers agreed with this approach, leading to a split from the main Bitcoin blockchain. At its inception, Bitcoin Cash could process between 1,000 and 1,500 transactions per block.
The History of Bitcoin Cash
The creation of Bitcoin Cash was the result of intense debate within the Bitcoin community regarding the best path toward scalability. One camp supported increasing the block size, while others preferred keeping blocks small and instead reducing transaction size through methods like SegWit. This disagreement ultimately led to the hard fork, producing two distinct chains: Bitcoin (BTC) and Bitcoin Cash (BCH).
This division was often described as a “civil war” between two competing visions. One faction, supported by entrepreneurs such as Roger Ver and Jihan Wu, promoted Bitcoin ABC (Adjustable Blocksize Cap), which maintained a 32 MB block size. Another group, led by Craig Steven Wright and Calvin Ayre, introduced Bitcoin SV (Satoshi Vision), which increased the block size limit to 128 MB.
Bitcoin Cash itself underwent further splits. Bitcoin SV forked from Bitcoin Cash in 2018, and Bitcoin Cash ABC (BCHA) was rebranded to eCash in 2021. Today, the BSV blockchain remains one of the largest Bitcoin forks, exceeding 2.5 TB in size.
Throughout its history, Bitcoin Cash has continued to increase its block size to improve transaction capacity. The block size was raised to 8 MB in 2018 and to 32 MB in June 2022. These adjustments were intended to help BCH scale more effectively and avoid the high fees and slow confirmations that plagued Bitcoin.
Key Controversies
The 2017 hard fork split the community into two main groups: those who supported Bitcoin Cash with its larger blocks, and those who preferred Bitcoin’s more conservative scaling path. Bitcoin Cash advocates emphasized its use as a medium of exchange, while Bitcoin supporters focused on its role as a store of value.
Critics sometimes refer to BCH as “Bcash” or use other derogatory terms, but supporters argue that it better reflects Bitcoin’s original purpose. Analysts like Brian Kelly have compared the hard fork to a contentious software update—one that lacked full consensus and led to ongoing rivalry between the two camps.
Samson Mow of Blockstream highlighted that the use of the “Bitcoin” name in Bitcoin Cash has been a continued source of tension. Emin Gün Sirer, a Cornell professor, noted that BCH is more focused on utility, while Bitcoin is intensely oriented toward value preservation. These philosophical differences continue to stimulate debate.
The BCH Token
Bitcoin Cash was created to serve as electronic cash for everyday transactions. Its community believes it aligns more closely with Satoshi Nakamoto’s original white paper, which described a peer-to-peer electronic cash system. BCH transactions are fast and cheap, often confirming in the next block with fees amounting to a fraction of a cent.
Like Bitcoin, BCH has a fixed supply capped at 21 million coins and uses a Proof-of-Work (PoW) consensus mechanism. The primary difference is the larger block size—32 MB compared to Bitcoin’s 1 MB—which allows more transactions per block and reduces congestion.
Instead of implementing Segregated Witness (SegWit), Bitcoin Cash adopted Schnorr signatures in 2019 to improve scalability and privacy. The network also uses a Difficulty Adjustment Algorithm (DAA) that recalculates mining difficulty after each block, contributing to a more stable mining experience.
Beyond payments, BCH also supports smart contracts. While not as versatile as Ethereum’s, these smart contracts enable use cases such as token issuance and some decentralized finance (DeFi) applications. This functionality was introduced in a later upgrade, opening the door to further innovation on the Bitcoin Cash blockchain.

The Future of Bitcoin Cash
Although not as prominent as Bitcoin, Bitcoin Cash remains one of the most recognized Bitcoin forks. It is accepted by many merchants and businesses due to its low fees and fast confirmations. However, some experts express concerns about network security, noting that larger blocks could potentially increase vulnerability.
Bitcoin is still considered the most secure blockchain, and its first-mover advantage gives it greater liquidity and adoption. For BCH to grow, it will need to continue differentiating itself from other cryptocurrencies, strengthening its platform, and expanding its use cases.
While it is unlikely to replace Bitcoin, BCH’s unique features and ongoing development could allow it to remain relevant in the diverse world of digital assets.
Is Bitcoin Cash a Good Investment?
When considering investing in Bitcoin Cash, it is important to evaluate its unique attributes and potential use cases. BCH may appeal to those who prioritize fast, low-cost transactions or are interested in the development of smart contracts on a Bitcoin-based platform.
That said, the cryptocurrency market is highly volatile, and all investments carry risk. Diversification and thorough research are essential. consulting with a financial advisor or investment professional is recommended before making any financial decisions.
Interesting Facts About Bitcoin Cash
- Bitcoin Cash itself has experienced several forks, including Bitcoin Cash ABC (now eCash) and Bitcoin SV.
- Bitcoin SV increased its block size to 128 MB but does not support smart contracts.
- Despite its larger block size, BCH blocks rarely exceed 1 MB in practice, which critics point to as a sign of underutilization.
- Some opponents argue that increasing block sizes is only a short-term scaling solution and may introduce long-term security risks.
How to Acquire BCH Tokens
You can buy Bitcoin Cash on many centralized cryptocurrency exchanges. The process usually involves creating an account, completing identity verification, depositing funds, and executing a trade. Always compare exchange rates and fees across platforms, and ensure you withdraw your BCH to a secure cryptocurrency wallet that you control.
