Bitcoin Cash (BCH) emerged from a hard fork of Bitcoin in August 2017, driven by developers, investors, and miners seeking improved scalability and lower transaction fees. Positioned as a peer-to-peer electronic cash system, BCH prioritizes faster transactions and affordability, aligning with Satoshi Nakamoto’s original vision for decentralized payments.
Key Features of Bitcoin Cash
1. Enhanced Scalability
- Larger Block Size: BCH increased Bitcoin’s 1MB block limit to 8MB (2017) and later 32MB (2018), enabling more transactions per block.
- Faster Confirmations: Targets a 10-minute block time, similar to Bitcoin, but with reduced congestion.
2. Low-Cost Transactions
BCH minimizes fees, making it viable for micropayments and everyday use—addressing Bitcoin’s rising fees in 2017.

3. Consensus and Mining
- Proof of Work (PoW): Like Bitcoin, BCH uses PoW but adjusts mining difficulty per block (vs. Bitcoin’s 2016-block interval).
- Supply Cap: Fixed at 21 million coins, with halvings every 210,000 blocks (~4 years).
4. Technical Upgrades
- Schnorr Signatures: Implemented in 2019 for improved privacy and efficiency.
- No SegWit: BCH rejected Segregated Witness, favoring block-size increases.
Bitcoin Cash vs. Bitcoin
| Aspect | Bitcoin (BTC) | Bitcoin Cash (BCH) |
|---|---|---|
| Block Size | 1MB (SegWit-adjusted) | 32MB |
| Fees | Higher during congestion | Consistently low |
| Adoption | Dominant market presence | Niche use cases |
Adoption and Challenges
While BCH is accepted by select merchants, adoption lags behind Bitcoin. Critics highlight security trade-offs from larger blocks, though proponents argue it better fulfills Bitcoin’s original use case.
The Bitcoin SV Fork (2018)
A contentious split created Bitcoin SV (BSV), advocating 2GB blocks. Despite backing from Craig Wright, BSV garnered limited support due to controversies.
Storing Bitcoin Cash
Popular wallets include:
- Hardware: Ledger, Trezor
- Software: Trust Wallet, Electrum Cash
- Mobile: Bitcoin.com Wallet, Coinomi
Note: BTC and BCH operate on separate blockchains—never interchange addresses.
FAQs
1. Is Bitcoin Cash faster than Bitcoin?
Yes, BCH’s larger blocks reduce congestion, enabling quicker confirmations.
2. Why did Bitcoin Cash fork from Bitcoin?
Disagreements over scaling solutions (block-size increases vs. SegWit) led to the split.
3. Can I use Bitcoin Cash for daily purchases?
While feasible, merchant adoption is sparse compared to Bitcoin.
4. How does BCH’s mining difficulty adjust?
Unlike Bitcoin’s 2016-block interval, BCH recalculates difficulty after every block.
5. What’s the max supply of BCH?
Capped at 21 million, mirroring Bitcoin’s scarcity model.
Conclusion
Bitcoin Cash remains a notable Bitcoin alternative, emphasizing affordability and speed. However, its smaller ecosystem and ongoing scalability debates limit mainstream parity with BTC.
For enthusiasts, BCH represents a compelling experiment in balancing decentralization with practical usability.
