Bitcoin Cash Definition: Bitcoin Cash (BCH) is a cryptocurrency created in August 2017 through a hard fork of Bitcoin, intended to function as “peer-to-peer electronic cash” with larger block sizes (32MB vs Bitcoin’s 1MB) enabling cheaper, faster transactions. The fork resulted from years of debate within the Bitcoin community: one faction wanted Bitcoin to remain “digital gold” with small blocks and high-security settlements, while another wanted Bitcoin to function as everyday payments with larger blocks and lower fees. BCH represents the latter vision. BCH uses the same proof-of-work consensus as Bitcoin and has a similar 21 million supply cap. However, BCH has significantly less hashrate than Bitcoin (~3% of BTC’s mining power), creating security concerns. BCH itself later split into Bitcoin Cash and Bitcoin SV in 2018 due to further ideological disagreements.
What Is Bitcoin Cash?
Bitcoin Cash was born from “the block size wars” — a years-long debate over Bitcoin’s future direction. Bitcoin’s 1MB block size limit meant only about 7 transactions per second could be processed. As Bitcoin grew popular, transaction fees climbed dramatically (sometimes $50+ per transaction in 2017), making small payments impractical.
One side argued: Bitcoin should be digital gold — store of value for large settlements, accepting high fees as the cost of maximum security. The other side argued: Bitcoin should be electronic cash for everyday payments — larger blocks would enable cheap transactions at the cost of some decentralization. When the debate couldn’t be resolved, the larger-blocks faction forked to create Bitcoin Cash.
How Bitcoin Cash Differs from Bitcoin
The technical and practical differences:
- Block size: BCH started with 8MB blocks (8x Bitcoin’s 1MB) and has since increased to 32MB. This enables ~200 transactions per second versus Bitcoin’s ~7 TPS.
- Transaction fees: BCH fees are typically $0.001–$0.01 versus Bitcoin’s $1–$50 depending on congestion. This makes BCH practical for small payments where Bitcoin would be cost-prohibitive.
- Mining difficulty adjustment: BCH uses a different difficulty adjustment algorithm that responds faster to hashrate changes, attempting to maintain stable block times.
- Same supply cap: Both Bitcoin and BCH have 21 million maximum supply with similar halving schedules.
- Security difference: BCH has roughly 3% of Bitcoin’s mining hashrate, making it more vulnerable to 51% attacks (though no successful attack has occurred to date).
Worked example: A small business wants to accept cryptocurrency. Customer pays $10 for coffee. On Bitcoin: $2–10 transaction fee, takes 10–60 minutes for confirmation, impractical. On Bitcoin Cash: $0.001 transaction fee, 10-minute confirmation, practical. Same security model (proof-of-work, similar economics) but different practical tradeoffs.
Why Is Bitcoin Cash Important for Traders?
BCH represents a specific philosophical position on what Bitcoin should be. Holders of BCH believe payments use case is essential and that Bitcoin failed by prioritizing store-of-value over transactional utility. ETH advocates favor Layer 2 solutions; BCH advocates favor Layer 1 scaling.
Practically, BCH has not achieved the adoption its creators hoped for. Most “Bitcoin payments” volume has moved to other solutions (Lightning Network on Bitcoin, stablecoins for stable-value payments, or other altcoins). BCH primarily exists as an alternative for ideological adopters and Bitcoin holders who received BCH “for free” during the 2017 fork.
On PrimeXBT, BCH CFDs offer exposure to a major Bitcoin fork with payments-focused philosophy. BCH exhibits volatility of 70–120% annualized, often correlating with Bitcoin but with additional volatility from its smaller market cap.
Key Takeaways
- Bitcoin Cash (BCH) is a 2017 hard fork of Bitcoin designed for “peer-to-peer electronic cash” with larger 32MB blocks (vs Bitcoin’s 1MB).
- BCH enables cheaper transactions ($0.001 vs Bitcoin’s $1–50) and higher throughput (~200 TPS vs Bitcoin’s ~7 TPS).
- BCH and Bitcoin share the same 21 million supply cap and proof-of-work consensus, but follow different philosophical paths.
- BCH has ~3% of Bitcoin’s mining hashrate, making it less secure against 51% attacks (though none have occurred successfully).
- On PrimeXBT, BCH CFDs offer 70–120% annualized volatility — correlated with Bitcoin but with extra volatility from smaller market cap.
