How Does the Efficiency of the Rented Mining Hardware Factor into the Attack Cost?

The efficiency of the rented mining hardware, measured in Joules per Terahash (J/TH), directly influences the cost the rental platform charges. More efficient hardware consumes less electricity for the same hashrate, which can lower the operational cost for the platform and potentially the rental price for the attacker.

While the attacker pays a flat rate for hashrate, the underlying efficiency determines the platform's ability to offer competitive, lower prices.
