Bitcoin Cash (BCH) is among the top cryptocurrencies designed to function as digital cash for daily transactions, akin to PayPal or credit cards. It emerged from a hard fork of the original Bitcoin blockchain, prioritizing scalability through larger block sizes.
Key Features of Bitcoin Cash
Block Size Increase:
- BCH expanded Bitcoin’s 1 MB block limit to 8 MB (later upgraded to 32 MB), enabling higher transaction throughput.
- Trade-off: Larger blocks raise operational costs for full nodes and may centralize mining power.
Smart Contracts & Scalability:
- The May 2018 upgrade introduced 32 MB blocks and Ethereum-like smart contract capabilities, further differentiating BCH from Bitcoin.
Decentralized Digital Cash:
- Peer-to-peer transactions.
- Fixed supply and irreversible transactions.
The Bitcoin Cash Hard Fork Explained
A hard fork splits a blockchain into two independent chains with shared history up to the divergence point. BCH’s fork resulted from unresolved debates within the Bitcoin community about scaling solutions:
- SegWit (Segregated Witness): Proposed code adjustment to "virtually" increase block capacity.
- Block Size Hike: Opponents advocated direct increases to 8 MB, leading to the BCH fork.

Why Bitcoin Cash Was Created
Background:
- Bitcoin’s 1 MB block size (introduced circa 2010) began causing bottlenecks by 2015.
- Transaction delays and fees surged as adoption grew.
Community Divide:
- Pro-SegWit: Favored code efficiency.
- Pro-Block Increase: Argued for straightforward capacity expansion via larger blocks.
The impasse culminated in the August 2017 hard fork, birthing Bitcoin Cash. Subsequent upgrades (e.g., 32 MB blocks) and the November 2018 split into BCH ABC and Bitcoin SV further shaped its evolution.
FAQ: Bitcoin Cash Essentials
Q1: How does Bitcoin Cash differ from Bitcoin?
A: Primarily in block size (BCH: 32 MB vs. BTC: 1 MB) and transaction speed/cost.
Q2: What was the Bitcoin SV fork?
A: A 2018 split creating Bitcoin SV ("Satoshi’s Vision"), aiming to revert to Bitcoin’s original protocol.
Q3: Is Bitcoin Cash decentralized?
A: Yes, but larger block sizes may favor institutional miners over individuals.
Buying Bitcoin Cash (BCH)
Purchase BCH on major exchanges like Bitstamp or Robinhood:
- Trade pairs: EUR/BCH, USD/BCH, BTC/BCH.
Note: Always verify regulatory compliance of your chosen platform.
Final Thoughts
Bitcoin Cash remains a pivotal scalability-focused cryptocurrency, though its technical trade-offs spark ongoing debate. For users prioritizing fast, low-cost transactions, BCH presents a viable alternative to traditional payment systems and Bitcoin itself.
