The cryptocurrency mining landscape has undergone significant shifts following the recent Bitcoin (BTC) halving on May 11, 2025. While much attention has focused on BTC’s post-halving performance, parallel developments in Bitcoin Cash (BCH) and Bitcoin SV (BSV) have revealed a compelling trend: a dramatic rebound in network hashrate after initial drops caused by their own earlier halvings in April.
As BTC’s block reward was cut from 12.5 to 6.25 bitcoins, miners recalibrated their operations across the Bitcoin ecosystem. The result? A temporary exodus from less profitable chains—followed by a strategic return as conditions rebalanced. Now, mining profitability across BTC, BCH, and BSV is nearly on par, reshaping miner behavior and network security dynamics.
Hashrate Recovery in BCH and BSV
Following their respective halvings on April 8 (BCH) and April 10 (BSV), both networks experienced sharp declines in computational power. Miner migration to more profitable chains—primarily BTC—led to an 80% drop in BCH’s hashrate within just two days of its halving. BSV saw similar outflows as mining rewards were halved from 12.5 to 6.25 coins per block.
However, data from bitinfocharts shows a strong recovery beginning in mid-May. By May 13, BCH’s hashrate had surged from 1.43 EH/s on May 10 to 2.74 EH/s—an increase of over 90%. Meanwhile, BSV’s hashrate climbed from 1.1 EH/s to 1.78 EH/s, signaling renewed interest and investment in these alternative proof-of-work chains.
This resurgence coincides with BTC’s post-halving hashrate decline, which fell 24% from 137 EH/s to 104 EH/s in the immediate aftermath. As BTC mining became less profitable for marginal operators, many redirected their hashing power back to BCH and BSV, where difficulty adjustments and stable transaction fees improved returns.

Miner Migration: From BTC Back to BCH and BSV
The mining economy operates on razor-thin margins, and small changes in block rewards or network fees can trigger large-scale hash migrations. After the April halvings, BTC emerged briefly as the most profitable chain, pulling hashpower away from both BCH and BSV.
But that advantage didn’t last. With BTC’s own halving reducing revenue per block, less efficient miners began shutting down rigs or switching chains. This created an opportunity window for BCH and BSV, whose networks had adjusted to lower baseline activity.
Major mining pools like F2Pool observed this shift firsthand. In statements shared via Twitter, F2Pool noted that BSV had become slightly more profitable than BTC, while BCH trailed only slightly behind: “BTC mining income is slightly below BSV, but slightly above BCH.” They added that profitability across all three chains now fluctuates closely due to dynamic difficulty adjustments and transaction fee structures.
Despite lower absolute transaction volumes compared to BTC, BSV’s network activity has been surprisingly robust. As of May 13, BSV processed 88% of the total transactions recorded on BTC’s blockchain, accounting for 54% of all cryptocurrency transactions during that period. Critics argue these are largely data-embedding transactions rather than peer-to-peer payments—but from a miner’s perspective, every confirmed transaction contributes to fee income and block value.
Transaction Fees: A Key Differentiator
One of the most striking contrasts between the networks lies in transaction fee behavior post-halving.
While BTC’s average transaction fee spiked—reaching a peak of $3.19 before the halving** and even hitting **nearly $100 for a single 1.2 BTC transfer on block 630001—BCH and BSV fees remained remarkably stable. Since mid-April, BCH fees have hovered around $0.0002**, while **BSV fees stabilized at approximately $0.002 per transaction.
Ed Pownall, a representative for BSV, criticized BTC’s rising fees, suggesting they reflect congestion rather than organic adoption:
“These fees aren’t driven by new users joining the network—they’re a sign of price gouging and network strain. It shows BTC has hit its limits in serving its community effectively.”
In contrast, BCH and BSV continue to promote themselves as scalable payment networks capable of handling high-throughput use cases without sacrificing low-cost access.

Mining Profitability Across Chains
Post-halving, mining economics have entered a new equilibrium:
| Chain | Block Reward (Post-Halving) | Avg. Transaction Fee (May 2025) | Relative Profitability |
|---|---|---|---|
| BTC | 6.25 BTC | ~$3–$5 (spikes over $50) | High volatility |
| BCH | 6.25 BCH | ~$0.0002 | Stable, rebounding |
| BSV | 6.25 BSV | ~$0.002 | Consistent |
Though raw fee income on BTC dwarfs that of its forks, the high entry cost (in terms of hardware and electricity) offsets gains for smaller miners. Meanwhile, BCH and BSV offer more predictable returns with lower competition and consistent demand for block space—especially from enterprises using the chains for data storage or microtransactions.
F2Pool and other large operators now treat all three chains as part of a diversified mining portfolio, dynamically allocating hashpower based on real-time profitability metrics.
Frequently Asked Questions (FAQ)
Why did BCH and BSV lose so much hashrate after their halvings?
After their April 2025 halvings, mining rewards for BCH and BSV were cut in half. This made them temporarily less profitable than BTC, prompting miners to redirect their computational power to the more lucrative Bitcoin chain.
What caused the recent rebound in BCH and BSV hashrate?
Following BTC’s May 11 halving, its mining profitability dropped sharply. As inefficient miners exited the network, others switched back to BCH and BSV, where difficulty adjustments and stable transaction fees restored competitive returns.
Are BCH and BSV more profitable to mine than BTC right now?
According to recent data from major mining pools like F2Pool, BSV is currently slightly more profitable than BTC, while BCH is close behind. These margins fluctuate daily based on price, fees, and network difficulty.
Why are BSV transaction volumes so high compared to BTC?
BSV’s high transaction count is largely due to non-payment use cases—such as timestamping, data anchoring, and smart contracts—rather than peer-to-peer transfers. These operations generate consistent fee income for miners despite low individual values.
Do low transaction fees on BCH and BSV mean weak demand?
Not necessarily. Low fees reflect design goals: scalability and accessibility. Both chains prioritize high throughput and low cost over fee revenue extraction. Demand remains steady from developers and businesses leveraging them for decentralized applications.
Could another chain overtake BTC in hashrate dominance?
Unlikely in the short term. BTC still commands the largest share of global mining power and investor trust. However, hashrate fluidity demonstrates that miners are highly adaptive—shifting resources rapidly when profitability changes.

Conclusion
The ripple effects of the 2025 Bitcoin halving extend far beyond BTC itself. The synchronized halvings of BCH and BSV in April triggered a cascade of miner migrations, network instability, and eventual rebalancing across the broader Bitcoin family.
Today, we see a more fluid and responsive mining ecosystem—one where computational power flows dynamically between chains based on profitability signals. For investors and participants alike, this underscores the importance of monitoring not just price movements, but also underlying network health indicators like hashrate distribution, transaction volume, and fee structures.
As the dust settles post-halving, one thing is clear: miners are not loyal—they are rational. And in this new era of interconnected proof-of-work networks, adaptability is the key to survival.
