Bitaxe NerdQaxe++ Hydro – 4.8 TH/s (75W) Silent Water-Cooled Bitcoin Miner (Wi-Fi)
Turn “lotto money” into hash power (quietly).
The NerdQaxe++ Hydro is a compact, open-source, home-friendly Bitcoin ASIC built for hobbyists who want real hashrate without the noise and power draw of industrial miners. With 4.8 TH/s at around 75W, it’s efficient enough to run as a desktop/mini-rig — and because it’s water-cooled, it stays quiet and comfortable for home environments.
Whether you want to experiment with solo “lotto” mining or join a pool for small sats payouts, the NerdQaxe++ Hydro is a powerful step up from entry-level hobby miners.
Want to understand solo mining first? Read: Solo bitcoin miner in South Africa (and our Bitcoin lottery miner guide).
Note: This is a hobby / educational miner. Mining outcomes are not guaranteed and depend on network difficulty, fees and BTC price.
