The halving events of Bitcoin (BTC), Bitcoin Cash (BCH), and Bitcoin SV (BSV) are pivotal moments in the cryptocurrency ecosystem. These events not only influence supply and demand dynamics but also reshape mining economics, market sentiment, and long-term network sustainability. In this comprehensive analysis, we explore the origins of these three major cryptocurrencies, their divergent design philosophies, and the profound implications of their upcoming halvings.
The Origins of BTC, BCH, and BSV
In 2008, Satoshi Nakamoto introduced the Bitcoin whitepaper, Bitcoin: A Peer-to-Peer Electronic Cash System, laying the foundation for a decentralized digital currency. The first block—known as the genesis block—was mined on January 3, 2009. Initially embraced by tech enthusiasts, Bitcoin gradually gained mainstream attention as user adoption and price surged.
However, by late 2013, network congestion became apparent. With a 1MB block size limit and an average of one block every 10 minutes, Bitcoin could process only about 4–7 transactions per second—far below the capacity needed for global payments. High fees and delayed confirmations sparked debates over scalability.
The Great Bitcoin Split
In 2015, the community split into two camps: those advocating for on-chain scaling through larger blocks, and others supporting off-chain solutions like Segregated Witness (SegWit) and the Lightning Network. After years of contention, a hard fork occurred on August 1, 2017, at block height 478,558. This gave birth to Bitcoin Cash (BCH), which increased the block size to 8MB (later expanded to 32MB) to enable faster, cheaper transactions.
BCH continued evolving with biannual upgrades, aiming to support smart contracts via re-enabled opcodes. However, ideological differences resurfaced in 2018 when Craig Wright—claiming to be Satoshi Nakamoto—opposed these changes. He advocated for restoring what he called the “original Bitcoin protocol” with massive on-chain scaling.
This led to another split in November 2018, creating Bitcoin SV (BSV). BSV removed fixed block limits entirely, eventually increasing block sizes up to 2GB during its "Genesis" upgrade. Its vision is to become a global public ledger capable of handling enterprise-level data storage and applications.

Today, BTC, BCH, and BSV represent three distinct visions: digital gold (BTC), peer-to-peer electronic cash (BCH), and a scalable data ledger (BSV).
Design Philosophies: Divergent Paths
Bitcoin (BTC): Digital Gold
BTC prioritizes decentralization and security over scalability. By maintaining a 1MB block size (post-SegWit effectively ~4MB), it ensures that running a full node remains accessible even on low-end hardware. To address congestion, BTC adopted SegWit in 2017 and launched the Lightning Network, enabling off-chain micropayments.
Despite these innovations, growth in Lightning Network adoption has been slow. As of recent data:
- Capacity: ~945 BTC
- Nodes: Over 12,000
- Payment channels: ~36,000
While functional for small transactions, Lightning has yet to achieve mass adoption. Consequently, BTC struggles with high fees during peak usage and is increasingly viewed not as "electronic cash" but as digital gold—a store of value rather than a payment medium.
Bitcoin Cash (BCH): Reviving Electronic Cash
BCH takes a different approach—scaling on-chain by increasing block sizes to 32MB. This allows more transactions per block, reducing fees and confirmation times. Additionally, BCH re-enabled several opcodes to support basic smart contracts and token creation.
Despite early momentum, development teams like Wormhole disbanded, slowing progress on dApps. Recent trends suggest BCH is refocusing on its core strength: fast, low-cost payments.
Global adoption reflects this shift:
- Over 2,557 crypto ATMs support BCH withdrawals or deposits (~34% of all crypto ATMs)
- Ranked fifth in ATM availability
- Still far behind BTC’s near-ubiquitous presence in over 7,470 ATMs
While growing, BCH's payment utility remains secondary to BTC in public perception.
Bitcoin SV (BSV): The Infinite Ledger
BSV pushes scalability further by removing block size caps entirely. After upgrading to 2GB blocks in July 2019, it set records for largest blocks mined. The goal? To create a worldwide public data ledger suitable for enterprise applications.
BSV emphasizes regulatory compliance and aims to attract businesses seeking a stable, auditable blockchain environment. However, concerns persist:
- Centralized control due to concentrated mining
- Price volatility linked to speculative trading
- Controversial leadership under Craig Wright
Still, BSV’s vision positions it as a competitor to platforms like Ethereum and Cosmos—not just as currency but as infrastructure.

BTC Halving: Supply Shock and Market Impact
Bitcoin’s monetary policy is algorithmically fixed: every 210,000 blocks (~4 years), the block reward halves. This deflationary mechanism caps total supply at 21 million BTC, making it resistant to inflation.
Historically, halvings have preceded bull markets:
- 2012 Halving: Price rose 82% within a year
- 2016 Halving: Price surged from $651 to $2,518 (3x increase) in 12 months
Market anticipation often drives prices upward before the event. But what drives this cycle?
Supply-Demand Dynamics
When supply decreases (due to lower mining rewards), prices tend to rise—assuming steady or growing demand. However, reality is more nuanced:
- Investors may front-run the halving, creating short-term bubbles
- Post-halving sell-offs can occur if expectations are priced in
- Long-term value depends on network adoption and trust
Miner Economics
Miners earn income from two sources: block rewards and transaction fees. Post-halving:
- Block rewards drop by 50%
- Mining becomes less profitable unless price rises
- High-cost miners may shut down operations
This triggers a feedback loop:
- Falling profitability → miner exodus → hash rate drops
- Lower hash rate → difficulty adjusts downward
- Remaining miners regain profitability → stability returns
The break-even price (or "shutdown price") for miners rises post-halving since they earn half the coins for the same electricity cost.
Key factors affecting mining costs:
- Electricity rates
- Hardware efficiency
- Network difficulty
- Block reward

BCH and BSV Halvings: Timing Differences Matter
All three networks use SHA-256, allowing miners to switch between them based on profitability. However, their halving dates differ slightly:
- BCH: April 8, 2020
- BSV: April 9, 2020
- BTC: May 2020
This timing gap creates temporary imbalances:
- BCH and BSV miners see rewards cut first
- If prices don’t double immediately, miners migrate to BTC
- Reduced hash rate on BCH/BSV increases risk of 51% attacks
Both BCH and BSV use DAA (Difficulty Adjustment Algorithm) that recalibrates difficulty every block based on recent hash power. This helps stabilize block times despite rapid miner movement.
Eventually, once all three networks halve, mining rewards rebalance across chains based on market prices and transaction volumes.
Frequently Asked Questions
Q1: What is a cryptocurrency halving?
A halving is an event where the mining reward for validating transactions is cut in half. It occurs at regular intervals to control inflation and maintain scarcity.
Q2: Why does halving affect price?
Reduced supply growth can create upward pressure on price if demand remains constant or increases—a classic supply-demand imbalance.
Q3: Do all cryptocurrencies halve?
No. Only those with deflationary monetary policies like BTC, BCH, and BSV undergo halving. Others may have fixed emissions or inflationary models.
Q4: Is mining still profitable after halving?
It depends on Bitcoin price relative to operational costs. Efficient miners in low-electricity-cost regions usually survive; others may exit or upgrade equipment.
Q5: Could halving lead to centralization?
Yes. As profitability drops, smaller miners may consolidate into large pools or shut down, increasing centralization risk in mining power distribution.
Q6: How do halvings impact everyday users?
Initially, users might see higher transaction fees due to miner reliance on fees over rewards. Long-term effects depend on adoption and network resilience.
