Miners Are Holding the Line But the Pressure Is Building

Bitcoin's hashrate has quietly crossed back above one zettahash per second, and that number deserves more attention than it is currently getting.

As of March 28, 2026, the network is running at 1.02 ZH/s — or 1,022 exahash per second. To put that in perspective, the seven-day average sat at just 931 EH/s on March 18. That means miners collectively added roughly 76 EH/s of raw computational power in ten days. In a market where sentiment is cautious and prices are under pressure, that kind of expansion speaks to a particular kind of conviction.

The economics, however, are tightening. Hashprice — the daily revenue a miner earns per unit of computing power — hit a March high of $33.85 per PH/s per day on March 25. Three days later it had already fallen 6.65%, settling at $31.60. That is a drop of $2.25 in less than a week, and these figures are sitting near lows not seen since Bitcoin was in its earliest years. Margins are thin. The runway is getting shorter.

What makes the situation more complicated is what is coming next. Blocks have been arriving faster than the standard ten-minute target, averaging one every nine minutes and twenty-three seconds over the past day. When blocks come in ahead of schedule consistently, the network responds by raising the mining difficulty. That next adjustment is due April 2, 2026, and the estimated increase sits at around 6.43%. For miners already operating on compressed margins, a difficulty increase means the same machines will earn less for the same work.

Transaction fees are not filling the gap either. Onchain fees accounted for just 0.43% of the total block reward over the past day, with fees sitting at 2.4 satoshis per virtual byte. The average transfer fee works out to roughly 27 cents per transaction — a figure that reflects a network that is functional but far from congested. Miners are currently earning around 3.14 BTC per block when fees are included, but without a meaningful uptick in network activity, that number has little room to grow from the fee side.

The picture this paints is one of resilience meeting reality. Miners are keeping their machines running despite conditions that would justify pulling back. That decision is either a calculated bet that price recovers before the economics force a harder choice, or simply the inertia of operations too large to wind down quickly. Either way, the industry is playing a waiting game right now — and April 2 will be the next real test of how long that patience holds.
