The recent surge in Bitcoin’s network hash rate has sparked widespread discussion across the cryptocurrency community. As mining difficulty adjusts to accommodate growing computational power, questions arise about its broader implications—not only for Bitcoin miners but also for alternative Proof-of-Work (PoW) blockchains like Bitcoin SV (BSV). This article explores the mechanics behind Bitcoin’s difficulty adjustment, the current trends in mining activity, and how these factors may be influencing BSV’s sudden price rally.
Understanding Bitcoin’s Mining Difficulty Mechanism
Bitcoin operates on a decentralized network where miners compete to solve complex cryptographic puzzles in order to validate transactions and add new blocks to the blockchain. To maintain network stability, a new block is designed to be mined approximately every 10 minutes.

To ensure this consistent block time despite fluctuating computational power, Bitcoin automatically adjusts its mining difficulty every 2,016 blocks—roughly every two weeks. When more miners join the network and hash rate increases, the difficulty rises to keep block production steady. Conversely, if miners leave the network, difficulty decreases.
In early January 2025, Bitcoin’s mining difficulty was adjusted upward by approximately 7% on January 15, marking the second such increase that month. Just 13 days earlier, on January 2, difficulty had already risen by 6.6%. This trend reflects a sustained increase in global hash rate since the second half of 2019, with only rare exceptions—such as a brief 7.1% difficulty drop on November 18, 2019.
This continuous rise signals strong miner confidence and significant capital investment in mining infrastructure. However, it also intensifies competition, raising operational costs and squeezing profit margins—especially for less efficient miners.
Mining Dominance and Geographic Distribution
Despite regulatory shifts in recent years, mining pools historically dominated by Chinese operators continue to hold a substantial share of global hash rate. These operations benefit from access to low-cost electricity and large-scale hardware deployment, giving them a competitive edge over counterparts in North America and Europe.
As difficulty climbs, only those with optimized setups—efficient machines, cheap power, and scalable operations—can remain profitable. This economic pressure is increasingly pushing marginal miners out of the Bitcoin network, especially those relying on older equipment like the Bitmain Antminer S9.
However, rising difficulty on Bitcoin doesn’t mean these machines are obsolete altogether.
The BSV Opportunity: Revival of Legacy Hardware
Bitcoin SV (BSV), a hard fork of Bitcoin Cash launched in 2018, has emerged as an attractive alternative for miners using older ASIC models. With its lower network difficulty compared to Bitcoin and a recent spike in market price, BSV has become profitable again for S9 miners who previously had to shut down due to unprofitability.
At the time of writing in mid-January 2025, BSV experienced a dramatic price surge—rising nearly 150% within 24 hours around January 14. Prices peaked above $400 before settling around $320, placing it competitively close to Bitcoin Cash (BCH), which traded at $342. This represents a roughly $200 increase from BSV’s price just one week prior.
Concurrently, BSV’s mining difficulty saw significant adjustments—mirroring the timing of Bitcoin’s own difficulty reset on January 15 at 7:42 UTC+8. While no direct technical link exists between Bitcoin’s difficulty adjustment and BSV’s price movement, the correlation suggests a potential shift in miner behavior.
Is There a Connection Between BTC Difficulty and BSV’s Rally?
There is no concrete evidence that Bitcoin’s difficulty increase directly caused BSV’s price explosion. The timing may be coincidental—or driven by other market forces.
One widely discussed catalyst is legal developments involving Craig Wright, the controversial figure who claims to be Satoshi Nakamoto and is a key proponent of BSV. Around January 10–14, reports indicated favorable progress in Wright’s ongoing court case related to the so-called “Tulip Trust,” potentially reigniting investor interest in BSV.
Still, the economic incentives for miners cannot be ignored. As Bitcoin becomes harder and more expensive to mine, some operators are reallocating resources to more accessible PoW chains. BSV’s combination of higher prices and feasible mining conditions has made it a compelling option.

Implications for Network Security and Market Competition
Mining hash rate plays a crucial role in securing PoW blockchains. A higher hash rate generally means greater resistance to attacks like double-spending or 51% takeovers.
While BSV’s growing hash rate does not currently threaten Bitcoin’s dominance, it could impact its peer networks—particularly Bitcoin Cash (BCH). If miners migrate en masse from BCH to BSV due to better profitability, BCH could face reduced security and slower transaction processing.
This competitive redistribution highlights a key dynamic in the PoW ecosystem: miners follow profit. When one chain becomes too costly to mine, capital and computational power naturally flow toward more lucrative alternatives—even if they are less prominent.
Frequently Asked Questions (FAQ)
Q: What triggers Bitcoin’s mining difficulty adjustment?
A: Difficulty adjusts every 2,016 blocks based on the average time it took to mine the previous set of blocks. If blocks were mined faster than 10 minutes on average, difficulty increases; if slower, it decreases.
Q: Why did BSV’s price surge suddenly in January 2025?
A: While no single cause is confirmed, possible drivers include legal developments involving Craig Wright and renewed miner interest due to improved profitability from rising prices and accessible mining conditions.
Q: Can old miners like the Antminer S9 still be profitable?
A: Yes—on lower-difficulty networks like BSV, especially when electricity costs are low and coin prices rise. Many S9 units previously shut down have now been reactivated for BSV mining.
Q: Does higher mining difficulty hurt Bitcoin?
A: Not inherently. Higher difficulty reflects network strength and security. However, it can squeeze smaller miners out unless they have efficient operations.
Q: How do hash rate changes affect other cryptocurrencies?
A: In the PoW space, miners often switch between chains based on profitability. A spike in one chain’s difficulty can lead to hash rate migration to others, temporarily boosting their security and mining rewards.
Q: Could BSV overtake Bitcoin Cash in popularity?
A: While unlikely in terms of long-term adoption, short-term shifts in price and mining activity can temporarily elevate BSV’s visibility and market position relative to BCH.
The Bigger Picture: Mining Economics Drive Market Movements
The interplay between mining difficulty, hardware efficiency, energy costs, and market prices forms the backbone of PoW cryptocurrency dynamics. The recent events surrounding Bitcoin’s difficulty hike and BSV’s price explosion illustrate how economic incentives guide miner decisions—and how those decisions ripple across the broader crypto market.
As networks evolve and competition intensifies, understanding these underlying mechanics becomes essential for investors, developers, and participants alike.
