Question 1

Is mining profitability guaranteed to remain constant?

Accepted Answer

No, mining profitability is not guaranteed to stay the same over time. This Canaan AvalonMiner 821 currently generates a daily profit of approximately -$2.47, assuming an electricity cost of $0.10 per kWh.  However, this profit can fluctuate due to various factors such as global hashrate, network difficulty, block reward, and cryptocurrency exchange rates. Be prepared for potential changes in profitability based on these market dynamics.

Question 2

What is the hashrate for this miner?

Accepted Answer

The Canaan AvalonMiner 821 has a hashrate of 11.5Th/s for the SHA-256 algorithm. Hashrates are only comparable between miners that use the same algorithm.

Question 3

Is the electricity consumption rate per hour?

Accepted Answer

Yes, the Canaan AvalonMiner 821 consumes 1200W per hour. Enter your local electricity price in the header preferences to see profitability calculations based on your actual electricity cost.

Question 4

How does electricity cost impact profitability?

Accepted Answer

Electricity expenses are a significant factor in mining profitability. 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 is even more important.

Question 5

What is the lifespan of this mining hardware?

Accepted Answer

The lifespan of mining hardware depends on factors such as usage intensity, environmental conditions (temperature, humidity, dust). Proper maintenance and ideal operating conditions can extend hardware longevity.
