Bitcoin Cash (BCH) is a peer-to-peer electronic cash cryptocurrency that emerged on August 1, 2017, as a hard fork of Bitcoin.
The fork arose from the “Block Size Wars” — a long-running dispute over how to scale Bitcoin, with proponents of this new chain arguing that increasing block size from 1MB to 8MB (later 32MB) stayed truer to Satoshi Nakamoto’s original vision of “peer-to-peer electronic cash” than Layer 2 approaches like the Lightning Network.
Launched by miners including ViaBTC and the Bitcoin ABC developer group, BCH quickly became one of the largest cryptocurrencies by market cap.
In 2018, the network split again into BCH and Bitcoin SV, led by Craig Wright.
Today, BCH maintains larger block sizes and cheaper transactions than BTC, and remains most used for remittances and everyday payments rather than as a store of value, though as of mid-2026, its network security has come under real strain (more on that below).

Origin & History of Bitcoin Cash (BCH)
| Date | Event |
|---|---|
| 2015–2017 | “Block Size Wars” split the Bitcoin community over scaling strategy |
| Aug 1, 2017 | Hard fork activates at block 478,559; launches with 8MB blocks |
| Dec 2017 | Price peaks near $4,000 during the crypto bull run |
| Nov 2018 | Second civil war splits the chain into BCH (ABC) and Bitcoin SV |
| Nov 2020 | BCHN wins miner support in a further contentious split; eCash (XEC) rebrand follows in 2021 |
| Apr 2024 | Second halving cuts the block reward to 3.125 coins per block |
| Feb 2026 | Network hashrate peaks near 5 EH/s ahead of anticipation of tightening supply |
| Apr 2026 | Third halving event; hashrate drops sharply from roughly 3.6 EH/s to a trough near 1.5 EH/s as reduced mining rewards push out less efficient miners |
| Jul 2026 | Price trades in the low-to-mid $200s, with market cap around $4.1B — down significantly from earlier-2026 levels amid broad altcoin weakness |

How It Works
| Feature | BCH | BTC | Litecoin (LTC) |
|---|---|---|---|
| Block Size | 32 MB | 1 MB (SegWit) | 1 MB |
| TPS | ~100–200 | ~7 | ~56 |
| Block Time | ~10 minutes | ~10 minutes | ~2.5 minutes |
| Avg. Fee | $0.001–$0.01 | $1–$50+ | $0.01–$0.05 |
| Supply Cap | 21 million | 21 million | 84 million |
| Smart Contracts | Limited (CashTokens) | Lightning only | No |
| Network Hashrate (2026) | ~1.5–3 EH/s, down sharply post-halving | Multiple hundred EH/s | N/A (different algorithm) |
| Primary Use | Electronic cash | Store of value | Payments |
In Simple Terms
- Bigger blocks, more capacity: The scaling approach here was simply raising the block size limit, keeping fees low without a second layer at the cost of higher storage requirements for node operators.
- Electronic cash philosophy: The design prioritizes being spendable digital money over being digital gold, following the original Bitcoin whitepaper’s title directly.
- Near-zero fees: Sending $100 typically costs under a cent, making it genuinely practical for remittances and micropayments.
- CashTokens (2023): Adds native fungible and non-fungible token support directly on-chain, without a separate smart contract layer.
- A widening security gap: Post-2026-halving, hashrate has fallen sharply, a real and growing concern, since lower hashrate means lower cost to attack the network relative to BTC’s vastly larger security budget.
Real-World Examples
| Scenario | Implementation | Outcome |
|---|---|---|
| Remittance use | Used for cross-border payments in countries with high inflation or currency controls | Popular where low fees matter more than store-of-value narratives |
| Merchant adoption | BitPay, CoinGate, and others added payment processing | Thousands of merchants globally accept it |
| CashTokens launch (2023) | Fungible tokens and NFTs launch natively | A small but real token ecosystem begins to form |
| 2026 halving | Block reward cut activates in April 2026 | Hashrate drops from ~3.6 EH/s to ~1.5 EH/s, raising real security questions |

Advantages
| Advantage | Detail |
|---|---|
| Near-zero fees | Consistently sub-cent fees regardless of congestion |
| On-chain scaling | No Layer 2 complexity — transactions settle directly |
| Fast, predictable confirmations | Same 10-minute blocks as BTC, but cheaper |
| CashTokens | Native token protocol without complex smart contracts |
| Long track record | Operating continuously since 2017 |

Disadvantages & Risks
| Risk | Detail |
|---|---|
| Falling hashrate | Post-2026-halving hashrate sits well below its early-2026 peak, a real and current security concern, not just a historical footnote |
| Lost mindshare | BTC won the dominant “Bitcoin” narrative; this chain is widely treated as an altcoin despite the shared history |
| Contentious history | Repeated splits (Bitcoin SV, eCash) have fragmented the community and diluted the brand |
| Development fragmentation | Competing client implementations create coordination friction |
| Limited smart contracts | CashTokens remains far more limited than Ethereum- or Solana-style DeFi |
Risk Management Tips:
- Ensure your wallet clearly distinguishes this from BTC addresses before sending or storing.
- Verify exchange support before depositing; some platforms have delisted it.
- Watch hashrate trends as a genuine security signal, not just a technical curiosity — the post-2026-halving decline is a real factor to weigh.
Frequently Asked Questions
Can it do smart contracts?
In a limited way — CashTokens (2023) adds native token support, but it can’t execute Turing-complete programs the way Ethereum’s EVM can.
Is the network less secure than Bitcoin’s?
Yes, meaningfully so. Its hashrate is a small fraction of BTC’s, and it dropped further after the April 2026 halving — a real, current gap rather than just historical trivia.
