Zcash miners are now earning roughly four times as much revenue per megawatt-hour as Bitcoin miners, according to new estimates from Grayscale — and the privacy coin’s network has more than 2.5 times the computing power it had at the start of 2026.

The Hook: The Most Profitable Mining Story of 2026 Isn’t Bitcoin
Grayscale Research Director Zach Pandl laid out the numbers: Zcash miners currently generate about 2 million USD in total revenue each day, compared with roughly 35 million USD across the entire Bitcoin network. Bitcoin’s total is far bigger because its network has vastly more machines. But on a per-machine basis, Grayscale estimates a Zcash miner earns about twice the daily revenue of a comparable Bitcoin miner — and per unit of electricity, roughly four times as much.
For anyone unfamiliar: miners are the computers that process transactions and secure a proof-of-work blockchain, paid in newly issued coins and fees. More revenue per megawatt-hour means each unit of electricity — the biggest cost in mining — produces more income. Under Grayscale’s assumptions, ZEC mining revenue per unit of electricity even beats some AI and high-performance computing cloud contracts.
On-Chain Evidence: Hash Rate Up 2.5x as ZEC Soared 2,300%
The mining boom traces directly to price. ZEC crossed above 1,000 USD for the first time on Sept. 4 after a 20% single-session gain, with about 34.5 million USD in short positions liquidated over 24 hours. The token is up roughly 2,300% year over year from about 42 USD in September 2025, with trading volume hitting 1.2 billion USD during the breakout and market capitalization near 16.8 billion USD.
- Zcash mining activity is up more than 2.5x since the start of 2026, per Grayscale.
- Revenue split — about 2 million USD daily for ZEC miners vs. about 35 million USD for Bitcoin’s whole network.
- Per-machine — a Zcash miner earns roughly 2x a comparable Bitcoin miner.
- Per megawatt-hour — roughly 4x Bitcoin’s revenue per unit of power.
- ZEC traded near 1,093 USD on Sept. 11, down close to 11% in 24 hours, per CoinGecko data.
Because Zcash uses the Equihash algorithm and Bitcoin uses SHA-256, miners cannot simply move the same hardware between networks — the machines are different, so the profit gap cannot be arbitraged away instantly by Bitcoin operators switching over.
The Core Conflict: A Reinforcing Cycle That Cuts Both Ways
Pandl described a self-reinforcing loop: a higher ZEC price makes mining more attractive, fresh machines raise the network’s hash rate, and added computing power makes the chain more expensive to attack. Stronger security then supports investor confidence in the asset itself.
But the cycle has a catch. Zcash automatically adjusts mining difficulty as computing power grows, so every added machine eventually makes each unit of hash rate less productive — unless prices or fee revenue keep climbing. Grayscale’s figures also compare revenue, not profit. Real earnings shrink after power rates, equipment prices, cooling, maintenance, facility costs and pool fees. And because block rewards are paid in ZEC, an 11% daily drop like Friday’s instantly cuts the dollar value of everything miners earn.
Supply adds another pressure point: like Bitcoin, Zcash caps supply at 21 million coins with scheduled reward reductions, meaning fewer new tokens for miners over time unless price gains offset the decline.
Market Implications: What This Means for Investors
You don’t need to run a mining farm to care about this. Hash rate is a security indicator — a network that keeps attracting more computing power is harder and costlier to attack. Grayscale argues that the mining boom is itself a bullish signal for ZEC’s long-term viability, since miners only commit hardware when the economics work.
U.S. investors also have an easier route to exposure than ever. Grayscale converted its Zcash Trust into a listed fund on NYSE Arca on Aug. 25 under the ticker ZCSH, with a 2.5% annual sponsor fee. The fund held more than 313.5 million USD in assets before listing, with Coinbase Custody as custodian and BNY Mellon as administrator. A filing amendment also disclosed that DCG subsidiary DCG International Investments was considering an investment tied to roughly 200,000 ZEC — though discussions were nonbinding.
Meanwhile, Bitcoin trades around 78,000 USD, and its mining industry remains vastly larger in absolute terms. The Zcash story is about efficiency per unit of power, not total scale.
The Verdict: Real Economics, Real Risks
Grayscale’s numbers are estimates, and mining economics can invert quickly — a sharp ZEC price reversal or a difficulty surge could erase the per-megawatt edge in weeks. But the underlying trend is verified: hash rate up 2.5x this year, revenue multiples over Bitcoin mining on an efficiency basis, and a listed ETF making exposure accessible to brokerage accounts.
For regular investors, the takeaway is simple: mining profitability follows price, not the other way around. The 2,300% annual gain did the heavy lifting. Watch whether hash rate growth continues if ZEC’s price cools — that would tell you whether miners genuinely believe in the network’s future or are just chasing this week’s yields.

4x revenue per mwh vs btc and zcash still only pulls 2m a day total. the second a big pool points machines at zec that edge evaporates, enjoy it while it lasts
hashpirate youre forgetting hashrate is already 2.5x since january and the edge held. difficulty adjusts, this isnt a free lunch forever but its not evaporating overnight either
difficulty already ran with the 2.5x hashrate though. the edge shrank and it still beats btc per mwh, thats the part people keep skipping
difficulty adjustment is the part you are leaving out tho. machines flood in, zec reward per mwh drops until the 4x gap closes on its own. the edge self corrects long before any single pool can dump on it

Grayscale putting out ZEC mining numbers the same week privacy coins need a bull case, call me paranoid but the timing is curious. Zach Pandl does lay out clean data though.
the most profitable mining story of 2026 is a privacy coin. regulators spent years squeezing zec and the miners eat good anyway
2M daily revenue network wide is tiny next to btc’s 35M tho. per mwh zec wins, aggregate is still no contest
aggregate no contest sure, but rig operators buy power by the mwh not by the network. that 4x number is what decides where machines get pointed
twice per machine, four times per megawatt. power is the biggest cost in mining so on the metric that pays the bills ZEC is winning right now
Twice the revenue per machine and four times per megawatt. Once GPU farm operators run the numbers, ZEC difficulty is going vertical.
zec is asic minable tho, gpu farms cant just point rigs at it. the difficulty spike comes from fpga and asic ops rerouting
Equihash ASICs exist but supply is thin. Difficulty can still run up fast if existing farm operators just reroute what they already run.
privacy coin mining being the profitable story of 2026 was not on my bingo card. hash more than 2.5x since January is wild
same, and 35M vs 2M daily shows Bitcoin scale is untouched. margin story, not a migration story
grayscale publishing flattering zec numbers right as they pitch a zec trust product to investors. wild timing coincidence
of course its flattering, grayscale did the same dance with their btc trust research notes. still, the 4x per mwh showed up in their own numbers so the bag has data
of course its flattering, they want the zec trust to look investable. but 2m daily revenue at 4x per megawatt is the data doing the selling, not the note
