Payback period
—
No payback while the machine runs at a loss
Revenue assumes a 1% pool fee at the current KAS 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 Payback needs a hardware cost, which we do not publish because we have no verified retailer feed — add your own purchase price in the calculator.

A $71 million fair-value writedown on the company's own bitcoin holdings offset the 8 per cent rise in mining revenue. Shares closed down 6.4 per cent on Friday ahead of the release.
It is the thirteenth solo-mined bitcoin block of 2026, and the second one in three weeks to hit for close to a full 3.1 BTC reward.
The $18.07 million loan from Arch Lending matured Friday afternoon with no public repayment notice, and the company has not filed the collateral terms.
