Antminer K7 (66Th)

As of May 7, 2026, considering an electricity cost of 0.045/KWh, the Antminer K7 (66Th) has been calculated to generate:

• Daily Revenue: $5.062
• Daily Electricity Cost: $3.46
• Daily Net Profit: $1.60

Projected earnings:
• Monthly Net Profit: $48.15
• Yearly Net Profit: $585.80

No, mining profitability is not guaranteed to stay the same over time. While the current daily profit is shown above, this can fluctuate due to various factors such as:

• Global hashrate changes
• Network difficulty adjustments
• Block rewards
• CKB Exchange rates

Be prepared for potential changes in profitability based on these market dynamics.

The Antminer K7 (66Th) has a hash rate of 66 TH/S with the Eaglesong algorithm. Note that hashrates are only comparable between miners that use the same algorithm.

Antminer K7 (66Th) has a rated power draw of 3201 W. Daily electricity cost is estimated from power draw, 24 hours of operation, and your selected electricity rate.

Electricity expenses are a significant factor in mining profitability. With the power consumption of 3201 W, your daily electricity cost is 3.46. Higher electricity rates can reduce or even eliminate profits, which is why assessing local energy costs is crucial when determining if mining is viable.

With higher electricity costs, investing in a highly efficient miner like this one (efficiency: 48.5 J/Th) becomes even more important.

The lifespan of mining hardware depends on several key factors:

• Usage intensity
• Environmental conditions (temperature, humidity: 10 - 90 %)
• Maintenance quality
• Cooling system (Air)

Proper maintenance and ideal operating conditions can significantly extend hardware longevity.

Bitmain is the manufacturer of the Antminer K7 (66Th).

The Antminer K7 (66Th) consumes 3.46 worth of electricity per day at the current rate of 0.045/KWh.
