Zettahash on the Horizon: Bitcoin’s Hashrate Nears 1 ZH/s as Miners Face Squeeze

As bitcoin’s valuation languishes near its weakest point since last year—with hashprice, the projected daily earnings for one petahash per second (PH/s) of mining capacity, receding to $40—the network’s computational muscle has paradoxically swelled to a historic peak.

Bitcoin Hashrate Hits Historic High Amid Price Plunge

This stretch has proven arduous for bitcoin miners, with earnings contracting sharply. On April 2, coinciding with former President Donald Trump’s unveiling of expansive trade tariffs, hashprice hovered at $48.45 before cascading to its current $40 per PH/s.

Compounding the strain, the mining complexity metric vaulted 6.81% just four days prior at block 891,072, settling at an unmatched difficulty of 121.51 trillion. Conventional logic suggests such a trifecta— BTC’s depreciating value, dwindling miner income, and heightened operational demands—would erode global computational output.

Yet the inverse unfolded: Bitcoin’s hashrate defied gravity, scaling to an unparalleled apex on Tuesday, April 8, 2025, per hashrateindex.com’s seven-day simple moving average (SMA). The metric briefly flirted with 926 exahashes per second (EH/s), inching within 74 EH/s of the elusive 1 zettahash (ZH/s) threshold.

By 9:30 a.m. ET on Wednesday, April 9, it moderated slightly to 921.06 EH/s, lingering near its stratospheric peak. Block intervals have mirrored the anticipated ten-minute norm, and while the impending difficulty recalibration on April 19 appears marginal, volatility still remains highly plausible.

Meanwhile, transactional lethargy across Bitcoin’s blockchain has sparked a curious stretch of underutilized blocks and diminished fee pressure. Presently, a premium transaction commands a modest 2 satoshis per virtual byte (sat/vB)—translating to a mere $0.22 per transfer—as demand wanes.

Over the past day, fee-derived income accounted for a paltry 1.32% of miners’ total rewards, exposing the ecosystem’s thinning profit margins. Yet, in a display of algorithmic defiance, the network’s computational might persists in scaling stratospheric heights.
