For a miner in Taiwan, running an ASIC at home almost always costs more than hosting it in the US, because Taipower bills homes on rising tiers and a single machine pushes the household into the top bracket: NT$7.03 per kWh from October to May and NT$8.86 per kWh from June to September, while Fathom Labs hosting is a flat $0.07 per kWh all-in. Here is the math for both seasons, with rates as of September 30, 2026, and what most Taiwan miners actually do about it.
Taiwan's tiered power eats the mining margin
Taipower residential rates (the household non-time-of-use tariff) are progressive: the more you use in a month, the more each additional kWh costs. Summer rates apply from June 1 to September 30, and lower non-summer rates apply from October 1 to May 31. The current table took effect on October 1, 2025, and Taiwan's electricity rate review committee left it unchanged from October 1, 2026 at its September 18, 2026 meeting, with the next review due in December 2026. As of September 30, 2026, the tiers per kWh are:
- 120 kWh and under: NT$1.78 in both seasons (about $0.056)
- 121 to 330 kWh: NT$2.55 summer (about $0.080), NT$2.26 non-summer (about $0.071)
- 331 to 500 kWh: NT$3.80 summer (about $0.12), NT$3.13 non-summer (about $0.10)
- 501 to 700 kWh: NT$5.14 summer (about $0.16), NT$4.24 non-summer (about $0.13)
- 701 to 1,000 kWh: NT$6.44 summer (about $0.20), NT$5.27 non-summer (about $0.17)
- 1,001 kWh and above: NT$8.86 summer (about $0.28), NT$7.03 non-summer (about $0.22)
Sources: the two-season table as published by Global Views Monthly (in Chinese), and UDN on September 21, 2026 (in Chinese) on rates staying the same from October 1. Most homes are billed every two months with each tier's kWh range doubled, which gives the same monthly result for a steady load like a miner.
An ASIC runs around the clock, so it burns through those tiers fast. A single 3.4 kW Whatsminer M70 uses roughly 3.4 times 24 times 30, or about 2,448 kWh a month, before your home's own air conditioning, fridge, and lights. That means most of the miner's power lands in the top two tiers, in either season.
Home vs hosted: the monthly power bill for one machine
How we estimated it: the low end assumes the miner is the only load in the home, so its 2,448 kWh climb the whole tier ladder. The high end assumes your household already uses more than 1,000 kWh a month, so every kWh the miner adds is billed at the top tier. Dollar figures use NT$31.876 per US dollar (Taipei interbank close, September 29, 2026) and are rounded estimates:
- Mining at home in Taiwan, non-summer (October to May): the miner's electricity alone runs about NT$13,800 to NT$17,200 a month, or about $430 to $540.
- Mining at home in Taiwan, summer (June to September): about NT$17,200 to NT$21,700 a month, or about $540 to $680.
- Mining at home in Taiwan, year-round average (4 summer months and 8 non-summer months, weighted by month): about NT$14,900 to NT$18,700 a month, or about $470 to $590.
- Hosting with Fathom Labs in Texas: the same 2,448 kWh at $0.07/kWh all-in is about $171 a month (about NT$5,500), in every season.
That is a gap of roughly $260 to $510 a month for one machine, depending on the season and your household's base usage. It compares power costs only and is not a profit forecast, because what a machine earns moves with bitcoin price and network difficulty.

Power is not the only problem at home
Cost is not the whole story. An ASIC's fans often run above 70 decibels, close to a vacuum cleaner, which is hard to live with in an apartment. It dumps heat all day, which makes your air conditioning work harder and stacks more cost on top of the power bill. It usually needs a dedicated 220V circuit and has to run 24/7 to be worthwhile. For most households those conditions are difficult to meet at home.
What Taiwan miners actually choose
The practical move is to put the machine somewhere power is cheap and built for ASICs. Fathom Labs hosts in Southeast Texas, served by Entergy Texas, at $0.07/kWh all-in: power, cooling, space, and monitoring, with no performance fee and no share of your bitcoin, so 100% of what you mine is yours.
You can buy Whatsminer hardware from us and host it, with no minimum quantity on machines bought from Fathom. If you already own machines, bring-your-own hosting is $0.08/kWh with a 10-unit minimum. Our hosting costs guide breaks down how the rate is built.
FAQ
How much does it cost to run one bitcoin miner at home in Taiwan per month?
Running one 3.4 kW miner around the clock at home in Taiwan uses about 2,448 kWh a month, which at Taipower's tiered residential rates (as of September 30, 2026) costs roughly NT$13,800 to NT$17,200 (about $430 to $540) a month from October to May and NT$17,200 to NT$21,700 (about $540 to $680) a month from June to September. The low end assumes the miner is your home's only load, and the more your household already uses, the closer you get to the high end. Hosting the same machine with Fathom Labs at $0.07/kWh all-in is about $171 a month.
Are mining machines loud and hot?
Yes. ASIC fans usually run above 70 decibels and the machine exhausts heat all day, which is hard to accommodate in a home or apartment. That is one reason many owners host in a purpose-built facility instead of mining at home.
If I host my miner in the US, is the bitcoin still mine?
Yes. At Fathom Labs you keep ownership of the machine and 100% of the bitcoin it mines. We charge only the flat $0.07/kWh all-in rate, with no performance fee and no share of your mined output.
Can I buy my own miner and then host it?
Yes. Bring-your-own hosting is $0.08/kWh with a 10-unit minimum, or buy hardware from Fathom Labs and host it with no minimum. Contact us for a quote.
