Performance Overview

The Antminer S21 XP 270 TH/s delivers outstanding performance due to its high hash rate and energy efficiency. Its hash rate of 270 TH/s allows for a significant increase in transaction processing speed, which directly impacts potential profit.

Hash Rate and Efficiency

A hash rate of 270 TH/s ensures you will mine Bitcoin faster than previous models. The high performance provides stable income and helps increase ROI (return on investment). This means the Antminer S21 XP will deliver quicker and more stable results compared to older models like the Antminer S19.

Energy Efficiency

With an energy efficiency of 13.5 J/TH, the Antminer S21 XP consumes significantly less power compared to previous models. This makes it more cost-effective to operate in regions with high electricity rates. Thus, despite its high power consumption of 3645W, energy costs are greatly optimized, making the model more profitable for miners.

Mining Profitability

Considering the current Bitcoin price and average electricity consumption, one can expect approximately $8.11 in daily profit. This can vary depending on operational conditions such as electricity prices and market fluctuations. It is important to note that with a decrease in electricity prices and an increase in Bitcoin value, profitability could significantly increase. This makes the Antminer S21 XP a wise investment, especially in areas with low electricity rates.
