How Does the Efficiency of a Miner (Joules per Terahash) Factor into the Break-Even Calculation?

Miner efficiency, measured in Joules per Terahash (J/TH), is the primary determinant of electricity cost for a given hash rate. A lower J/TH means the miner consumes less power for the same output.

This directly reduces the operational expense, lowering the break-even price of the cryptocurrency and extending the miner's profitable lifespan, especially in regions with high electricity costs.
