Every public ASIC profitability calculator defaults to a power price of 10 cents per kWh. Almost no professional host actually pays that. The real number for a competitive U.S. hosting facility is closer to 7 cents, and that three cent gap completely reorders which machines are worth buying.
We pulled the live global rankings and recomputed every machine at a flat 7c/kWh. Bitcoin hashprice has stabilized around $32.56 per PH per day after the June slide, but the leaderboard still moved: Zcash revenue ran roughly 30 percent higher over the past month, which put the Antminer Z15 Pro at #1 in the world, while Monero cooled and pushed last month's leader down to #3. The figures below are gross daily hash revenue minus a 7c power bill, giving you the true net profit per day for every machine on the list.
The Top 10 at 7c/kWh

Three That Tell the Story
The full table is above. These three explain what changed in July and why the 7c basis matters.
#1 - Bitmain Antminer Z15 Pro (840kh): the new world leader, in stock
840 kh/s Equihash • 2,780 W air-cooled • $33.39 gross/day • $28.72 net/day at 7c • ~$10,483/year • our price $8,250
The most profitable machine on the global table this month, and you can buy it today. Zcash revenue ran roughly 30 percent higher over the past month while Bitcoin hashprice went sideways, and that pushed the Z15 Pro from #2 to the top of the global table. At 2,780 watts its power bill at 7c is only $4.67/day, so it keeps $28.72 of its $33.39 gross. We have stock at $8,250, which this machine pays back in about 9.4 months at current profit, the fastest payback of any machine in this ranking. Machines earning at this level do not tend to stay in stock, and Equihash revenue at this altitude is the reason.
#2 - Bitmain Antminer S23 Hyd 3U (1,160Th): the machine the public calculators hide
1.16 PH/s SHA-256 • 11,020 W hydro-cooled • $37.77 gross/day • $19.25 net/day at 7c • $11.32 net/day at the public 10c default
The S23 Hydro 3U produces the highest gross revenue on the entire list at $37.77/day, the most powerful Bitcoin miner Bitmain makes. But it draws 11,020 watts, so the power price dominates its economics. At the 10c default the public sites use, it nets $11.32 and ranks fourth. Drop the rate to a realistic 7c and its net jumps to $19.25, a gain of nearly $8/day, and it becomes the most profitable Bitcoin miner in the world. No machine on this list benefits more from a competitive hosting rate, and that is the entire argument for hosting big hydro hardware where power is cheap rather than running it at home.
#10 - Bitmain Antminer S21e XP Hyd 3U (860Th): the proof case, also in stock
860 Th/s SHA-256 • 11,180 W hydro-cooled • $28.00 gross/day • $9.22 net/day at 7c • $1.17 net/day at 10c • our price $11,730
At 10 cents this machine makes $1.17 a day and the public rankings bury it. At 7 cents it makes $9.22 and cracks the world top 10. No machine on the list illustrates the rate argument more sharply: the difference between marginal and genuinely profitable is nothing about the hardware and everything about the power price behind it. It is also one of only two top-10 machines you can buy and rack today, in stock at $11,730 for 860 terahash of current-generation Bitcoin hashrate. If you want big BTC exposure now rather than waiting on an S23 batch, this is the machine, and it only makes sense at a real hosting rate.
What Changed in July
Bitcoin hashprice stabilized; the altcoins moved. After sliding roughly 30 percent through June, Bitcoin network revenue has held near $32.56 per PH per day for a month. The July reshuffle came from the other algorithms: Zcash revenue ran about 30 percent higher, lifting the Z15 Pro to #1 and the smaller Z15 to #6, while Monero cooled about 14 percent and dropped the X9 from the top spot to #3. If you bought a Z15 Pro in June, your machine now earns more per day than when you ordered it.
The power price is still the whole story for Bitcoin machines. A machine's gross revenue is fixed by its hashrate and the network. The only thing a hosting rate changes is the electricity bill, and that bill scales directly with power draw. The S23 Hydro 3U spends $26.45/day on power at the public 10c default and only $18.51 at 7c; the machine did not change, the rate did. Every SHA-256 unit in the top 10 is a high-draw hydro machine for exactly this reason.
The S21e XP Hydro is the proof case. At 10c it earns about a dollar a day and no public ranking will surface it. At 7c it clears $9/day and makes the world top 10. Buyers who shop on the public number never see it, which is part of why it is still in stock while the S23 family is on batch allocation.
This is where a host earns its keep. At 7c the field looks healthy. At 10c half of it looks marginal. The single most valuable thing you can do before buying any of these machines is lock a real hosting rate, because the rate, not the hardware, decides which side of profitable you land on. That is the number to get in writing first. Our hosting page covers how we structure rates across 11 U.S. facilities.
Methodology and disclosures
Rankings are sourced live from ASIC Miner Value on 2026-07-17. ASIC Miner Value computes profit at a $0.10/kWh default; because that figure is calculated in the browser and cannot be set externally, we recover each machine's electricity-independent gross daily revenue and recompute net profit at $0.07/kWh (gross minus rated power draw x 24 hours x $0.07). For Bitcoin machines, gross is computed directly from on-chain hashprice of $32.56 per PH per day as of 2026-07-17 19:02 UTC (144 blocks/day x 3.1511 BTC average reward including fees x $64,224 BTC price / 895.12 EH/s network hashrate; source mempool.space); this method matched ASIC Miner Value's displayed figures within $0.06/day on every machine checked. Revenue changes daily with coin price, network difficulty, and fees; figures shown are a snapshot, not a guarantee. The 7c rate is a standardized industry benchmark for illustration; your contracted hosting rate determines actual net. Machine prices include MiningStore margin and are subject to availability.
