Equihash · air-cooled
Half the hashrate of the Z15 Pro at around 60% of the power. Aging hardware on a niche algorithm — a speculative purchase rather than an infrastructure one.

Payback period
—
No payback while the machine runs at a loss
Revenue assumes a 1% pool fee at the current ZEC price and network difficulty, with the machine running continuously. Payback needs a hardware cost, which we do not publish because we have no verified retailer feed — add your own purchase price in the calculator. Your rate is saved in this browser and applies across the site.

The miner's self-mining hashrate rose to 79.9 EH/s and production was up about 249 percent from a year earlier, but its bitcoin balance ended the month at 61 coins, against 257 a month earlier and 1,934 a year ago. The company's own footnote says the figure counts coins pledged as collateral, which rules out one explanation for the drop.
The Ways and Means Committee marked up H.R. 10357 on Wednesday morning, a day after the CLARITY Act stalled in the Senate. The bill waives tax on network fees of $10 or less from 2028, but settles only that staking and mining rewards are ordinary income, not when they are taxed.
Nearly 2.4 million ZEC took part, about two-thirds of the eligible supply, and 98.9 percent chose bitcoin-style halvings over a smoothed issuance curve. The result is advisory: NU7 still needs code, testing and a ZIP activation.
