Hydro and air-cooled Antminer hosting in Paraguay: S21 and S23 series for Bitcoin, L9 and L11 for Litecoin and Dogecoin. Verified specs, quotes at today's China price.
This is not a shop and there is no checkout — you cannot pay here and we would not want you to. Build a list, send it, and we come back with the real cost from China plus your electricity tier. Hydro is Bitmain only; for air-cooled, tell us the model and we source it.
The entry into hydro: S21+ efficiency at the lowest price in our liquid loop.
The bigger S21+ bin: more hashrate in the same 15 J/TH class.
S21e XP generation at 13 J/TH — the middle of the hydro range on price and efficiency.
5-nm S21j XP chips at 12 J/TH: the most hashrate on the list under $10,000.
The first Bitcoin miner to break below 10 J/TH. Our default recommendation for anyone starting now.
The most efficient machine we host: 8.9 J/TH at 600 TH/s. The flagship.
Hydro machines run inside the HK3 container on a closed distilled-water loop. Bitmain only here — the loop is built to their fittings and pressures. Prices current as of 2026-09-06. We update them whenever they change and confirm the exact price before every purchase — everything is included except the deposit; prices in China can move with Bitcoin, the season and the wider market.
The list above is what we host most often, not a limit. If the model you want is not there — another manufacturer, another algorithm, a machine that only just launched — tell us what it is. Our suppliers in China can source most units, and you get a price back rather than a shrug.
Send us the model and quantity you are considering. We verify today's price in China, calculate your electricity tier and come back with a written offer — no obligation, no pressure.
