If you're looking to add an efficient air-cooled Bitcoin miner to your setup, the MicroBT WhatsMiner M70S+ 244Th/s Bitcoin ASIC Miner is a serious contender. It's built for the SHA-256 algorithm, meaning Bitcoin (BTC) mining, and delivers professional-tier hashrate without the complexity of a hydro or immersion deployment.
Here's what you actually get. The Bitcoin ASIC delivers 244 TH/s of hashrate at 12.87 J/TH efficiency, and efficiency is the number that decides whether your operation is profitable at any given power cost. Anywhere above $0.06/kWh, the efficiency gap between this unit and older hardware compounds into real revenue over a year of uptime.
MicroBT has refined the thermal design and component quality on this generation to the point where you can rack a unit, plug it in, and let it run for months without touching it. If you're currently mining on older S-series, M-series, or Avalon hardware, the upgrade math is hard to argue with, the efficiency delta alone pays for the unit inside one mining cycle at most operating power rates.
Shipping is DDP-paid on every order over $5,000, duties and taxes are handled before delivery, so you don't deal with customs. Pay with Bitcoin for a 3% discount on your entire order. The Miner Island tests every unit before dispatch.

Every order over $5,000 ships DDP-paid from our Hong Kong warehouse, so duties, taxes, and customs clearance are paid before the unit reaches you. You won't get a surprise invoice from the courier on delivery day.
Most orders dispatch within 24 to 72 hours of payment confirmation. Transit time runs 3 to 7 business days to North America, Europe, and the major mining jurisdictions. We share the tracking number the moment the airwaybill is issued.
Every unit carries a 60-day warranty from the date you receive it. Manufacturer warranties (typically 180 to 365 days depending on the brand) run in parallel and we'll help you process those claims directly with Bitmain, MicroBT, Canaan, Goldshell, IceRiver, or Elphapex.
If your unit arrives dead-on-arrival (won't power on, fails the initial hashrate test, or has visible transit damage), we replace it. Document the issue within 72 hours of delivery (a short video or photo set is enough), and we'll ship the replacement.
We accept Bitcoin, Ethereum, Litecoin, USDT, USDC, and a handful of other major cryptos through Plisio. Pay in any crypto and save 3% on your entire order. The discount applies automatically at checkout. For bulk orders over $25,000, message us on WhatsApp to discuss 50/50 staged crypto payment options.
Live estimate based on this unit's hashrate, efficiency, and coin price.
Network difficulty, coin price, and uptime all move. Treat this as a sanity-check, not a guarantee. Baseline issuance data is calibrated to May 2026; numbers drift as networks evolve. We're happy to walk through your specific power cost and target hashrate on WhatsApp.
