Following the significant drop in hashrate experienced by Bitcoin Cash (BCH) and Bitcoin SV (BSV) after their April halving events, both networks have shown a notable recovery. This resurgence coincides with Bitcoin's own halving on May 11, which saw its hashrate decline, making alternative chains comparatively more attractive for miners once again.
Post-Halving Hashrate Dynamics
The hashrate, or the total computational power securing a blockchain network, is a direct indicator of miner activity and network health. Both BCH and BSV underwent their reward halving events in early April, where the block reward for miners was cut from 12.5 to 6.25 coins.
Immediately after these events, both networks witnessed a dramatic exodus of mining power. BCH's hashrate plummeted by over 80% within days as miners shifted their resources to more profitable chains, primarily Bitcoin. A similar flight was observed on the BSV network.
The Recent Hashrate Rebound
Data from on-chain analytics providers shows a strong recovery for both BCH and BSV starting around May 10th. Bitcoin Cash's hashrate surged by over 90%, climbing from 1.43 EH/s to 2.74 EH/s by May 13th. Similarly, Bitcoin SV's computational power increased from 1.1 EH/s to 1.78 EH/s in the same period.
This recovery phase began just as Bitcoin itself underwent its much-anticipated halving. Following its event, Bitcoin's hashrate dropped by approximately 24%, from a high of 137 EH/s down to around 104 EH/s. This decrease, while significant, was less severe than the drops seen on BCH and BSV a month prior.
Mining Profitability Becomes Comparable
The primary driver for miner movement is profitability. After Bitcoin's halving reduced its block reward, the mining revenue across all three chains—BTC, BCH, and BSV—has converged to roughly similar levels.
Major mining pools have publicly commented on the shifting economics. They noted that mining profitability between the three networks is now very close, a significant change from the period immediately after the April halvings when Bitcoin was the unequivocally most profitable chain to mine.
The Role of Transaction Fees
Block rewards are only one part of the miner revenue equation; transaction fees also contribute.
- Bitcoin (BTC): Transaction fees on the Bitcoin network saw a substantial spike leading up to its halving, with the average fee peaking at multi-dollar levels. There were even reports of single transactions paying fees as high as $100, which some critics argue indicates network congestion and high costs for users.
- Bitcoin SV (BSV) & Bitcoin Cash (BCH): In contrast, transaction fees on both BSV and BCH have remained minimal and stable, largely unaffected by the halving events. Fees have consistently stayed at a fraction of a cent, by design, to promote low-cost transactions and data recording.
This difference in fee markets presents a contrasting philosophy: Bitcoin prioritizes security through high fees paid for block space, while BSV and BCH aim for high-volume, low-cost transactions.
Analyzing the Network Activity
A point of continued discussion is the nature of the transaction volume on these networks. BSV, in particular, has been reported to have a transaction volume that sometimes rivals or even exceeds that of Bitcoin. However, commentators often note that a significant portion of this activity is attributed to data recording rather than purely peer-to-peer financial transfers.
Despite the debate over the nature of these transactions, the high volume contributes to the security of the BSV chain by including more transactions in each block, though the fee revenue for miners from this activity remains low.
The Miner's Choice
Miners are pragmatic. Their decision on which chain to dedicate resources to is based on a simple profit-and-loss calculation. The recent hashrate migration back to BCH and BSV clearly indicates that, at current difficulty levels and coin prices, mining these chains is once again economically viable compared to Bitcoin.
This equilibrium in profitability suggests a new balance has been found in the post-halving landscape. Miners will likely continue to switch between chains dynamically to maximize their returns, a process made possible by the shared SHA-256 mining algorithm.

Frequently Asked Questions
What does "hashrate" mean?
Hashrate refers to the total combined computational power that miners are using to secure a proof-of-work blockchain network and process transactions. A higher hashrate generally indicates a more secure network that is more resistant to attack.
Why did miners leave BCH and BSV after their halving?
When the block reward for BCH and BSV was cut in half in April, the immediate revenue for miners mining those chains was suddenly reduced. If the price of the coin did not double to compensate, mining became less profitable overnight. Miners quickly shifted their powerful equipment to the most profitable chain, which at that time was Bitcoin.
Why did they return to mining BCH and BSV?
They returned because the profitability landscape changed. After Bitcoin itself had its halving on May 11th, its block reward was also cut in half. This made mining Bitcoin less profitable for some miners, especially those with less efficient operations. As Bitcoin's hashrate dropped, the mining difficulty for BCH and BSV became relatively more attractive, drawing miners back.
Are BCH and BSV as secure as Bitcoin?
Security is measured by hashrate and the cost to attack a network. Bitcoin has a vastly higher hashrate than BCH and BSV combined, making it the most secure by a significant margin. However, the recent recovery in hashrate for BCH and BSV has increased their security from their post-halving lows.
What are the main criticisms of the different fee models?
Critics of Bitcoin's high-fee model argue it makes the network expensive to use and less practical for small everyday transactions. Critics of BSV's and BCH's low-fee model argue that it provides less long-term security for the network once block rewards diminish further, and that high transaction volumes can be inflated by non-financial data storage.
How can I track mining profitability?
Mining profitability depends on many variables, including electricity costs, hardware efficiency, current network hashrate, and cryptocurrency prices. You can 👉 explore more strategies and track real-time metrics using specialized online calculators and dashboards that aggregate this data.
