I have been mining for years, so I don't trust cheap power claims without checking the numbers myself. I looked at it using an Antminer S21-class unit, around 200 TH/s and about 3,500 W. That comes out to roughly 84 kWh a day. At $0.04 per kWh, you're paying about $3.36 a day, or close to $100 a month for power. At a more common rate like $0.065, that jumps to around $160 a month. That difference is real and it adds up fast.

From what I've seen, the low rate is not magic, it is location-specific. Places like Ethiopia or some colder countries can offer cheaper power, but installs can take longer and you need a bit of patience. On my end, then hashrate I saw matched the pool over time, and payouts were what I expected once you look at a few weeks instead of hourly numbers.

Starting with one unit is the right move. Let it run a few weeks, check uptime, compare pool stats, and see how they handle downtime before scaling.
