What Is Bitcoin Cash (BCH)?
Bitcoin Cash (BCH) is a peer-to-peer electronic cash cryptocurrency that was created in August 2017 as a hard fork of Bitcoin. The fork emerged from a fundamental disagreement within the Bitcoin community over how to scale the network to handle more transactions. Proponents of Bitcoin Cash argued that increasing the block size limit was the correct path to achieving fast, cheap, on-chain payments — the original vision outlined in Satoshi Nakamoto's whitepaper.
Bitcoin Cash increased the block size from Bitcoin's 1MB limit to 8MB at launch, later expanding to 32MB. This allows BCH to process significantly more transactions per block compared to Bitcoin, resulting in lower fees and faster confirmation times when the network is active. The trade-off is a larger blockchain that requires more storage and bandwidth to run a full node.
The Block Size Debate and the Fork
The dispute that created Bitcoin Cash centered on Bitcoin's scalability problem. As Bitcoin grew in popularity through 2016 and 2017, the mempool became congested and transaction fees spiked to tens of dollars — making small payments economically unviable. Two camps emerged: those who favored increasing the block size (on-chain scaling) and those who preferred off-chain solutions like the Lightning Network.
When the Bitcoin community settled on the SegWit2x path and Lightning Network development, a group of miners, developers, and businesses led by Roger Ver and Jihan Wu activated the Bitcoin Cash hard fork on August 1, 2017. Every Bitcoin holder at the time received an equal amount of BCH — a common mechanism in hard forks. Bitcoin Cash then underwent a further split in November 2018, producing Bitcoin SV (BSV), led by Craig Wright.
Bitcoin Cash Tokenomics
BCH shares Bitcoin's core monetary policy: a fixed maximum supply of 21 million coins and a halving schedule approximately every four years that reduces the block reward by 50%. BCH uses the same proof-of-work consensus mechanism as Bitcoin, with SHA-256 mining. This means BCH competes with Bitcoin for mining hashrate, which has historically been a point of vulnerability during periods of low BCH price relative to BTC.
The BCH halving schedule runs in parallel with Bitcoin's, and mining economics closely track the BCH/BTC price ratio. When this ratio falls, miners tend to switch back to Bitcoin, which can temporarily reduce BCH network security until difficulty adjusts. You can explore how mining economics work in our Bitcoin mining economics guide.
Use Cases and Adoption
Bitcoin Cash is designed primarily as a medium of exchange — digital cash for everyday transactions. It has seen meaningful merchant adoption in some regions, particularly through initiatives like Bitcoin.com's wallet ecosystem and merchant directories. BCH transaction fees are typically a fraction of a cent, making it viable for small payments that would be impractical on Bitcoin's base layer.
BCH also introduced smart contract capabilities through CashScript and the Simple Ledger Protocol (SLP) for token creation, though these ecosystems have not achieved the scale seen on Ethereum. DeFi activity on BCH remains limited compared to major smart contract platforms. For users focused purely on fast, cheap crypto payments, BCH competes with Litecoin and XRP in the payments-focused crypto segment.
Where to Trade Bitcoin Cash
BCH is listed on virtually every major cryptocurrency exchange. For spot trading with high liquidity, Coinbase, Kraken, and Binance are the primary venues. BCH is also widely available on regional exchanges and peer-to-peer platforms, reflecting its positioning as an accessible payments currency.
Trading volume for BCH is generally lower than for top-ten assets like Solana or Cardano, which can mean wider spreads during volatile periods. Always check the order book depth before entering large positions. Our order book depth guide explains how to evaluate liquidity before trading.
Price History and Market Position
BCH reached its all-time high of approximately $4,355 in December 2017, during the initial fork-driven excitement and the broader crypto bull market. It has since traded well below that level, and its market cap dominance relative to Bitcoin has declined significantly. Critics argue this reflects the market's verdict that Bitcoin's Lightning Network and security-first approach won the scaling debate.
Supporters counter that BCH's low-fee transactions provide genuine utility that Bitcoin's base layer cannot replicate affordably, and that its on-chain payment use case remains relevant. BCH continues to rank in the top 20 cryptocurrencies by market capitalization and maintains active development and community support.
Technical Analysis and Trading BCH
BCH tends to follow Bitcoin's price direction but with amplified moves — both upside and downside. It often outperforms BTC during aggressive altcoin season conditions and underperforms during flight-to-safety periods when capital concentrates in Bitcoin. Traders monitoring the BCH/BTC ratio can identify relative strength shifts. Our relative strength guide covers this kind of pair analysis in depth.

Summary
Bitcoin Cash represents one of crypto's most significant ideological forks — a genuine attempt to build peer-to-peer electronic cash at scale. Whether it succeeds in the long run depends on merchant adoption, continued development, and the broader market's appetite for payment-focused cryptocurrencies. It remains an important part of crypto history and continues to serve users who prioritize low-cost on-chain transactions. Keep up with BCH developments and the broader market on our DennTech blog.
Bitcoin Cash's long-term case rests on the premise that eventual global adoption of cryptocurrency for everyday transactions requires a base layer capable of handling that volume affordably — a premise that small-block advocates reject in favor of layer 2 solutions like the Lightning Network. This fundamental disagreement about Bitcoin's destiny remains unresolved, and BCH represents the minority view that won a contentious battle for the Bitcoin name before losing the broader market share war. BCH's continued development, merchant adoption tooling, and active developer community mean it has not faded despite being dramatically outperformed by Bitcoin in market cap terms over the same period.
BCH is available on Coinbase, Kraken, Binance, and most major exchanges. It tends to outperform during periods when Bitcoin transaction fees spike and the scaling debate re-enters public discourse. Our DennTech blog covers BCH developments and the ongoing Bitcoin scaling narrative.
