ASIC Miners

Bitmain Antminer leads in raw SHA-256 hashrate with the S21 XP series (300+ TH/s). MicroBT WhatsMiner offers competitive efficiency, often 5-10% better J/TH than equivalent Antminers. Canaan Avalon is the most budget-friendly option with proven reliability. All three brands mine Bitcoin and Bitcoin Cash; WhatsMiner M60S series also supports Litecoin/Dogecoin via Scrypt algorithm.

Rule of thumb: $1,000 budget = ~50 TH/s at current market. Use our Mining Calculator (/calculator) to enter your electricity cost and see daily/monthly profit. For North America (0.06-0.10 USD/kWh), 200+ TH/s units break even faster. For low-cost regions (0.03-0.05 USD/kWh), even 100 TH/s units remain profitable through the next halving.

3-5 years under normal operating conditions. Hash boards typically last 40,000-60,000 hours (~5-7 years continuous run). Power supplies last 3-5 years. Control boards can last 5+ years. We recommend preventive maintenance every 6-12 months: dust cleaning, thermal paste replacement, fan inspection.

Yes. Every miner ships with the latest stable firmware. We support both stock and custom firmware (Braiins OS+ for Bitmain, Vnish for WhatsMiner, LuxOS for Canaan). Custom firmware typically improves efficiency by 5-15% through undervolting and autotuning. We provide free flashing and tuning for bulk orders (10+ units).

SHA-256 ASICs (Antminer S series, WhatsMiner M series) can mine Bitcoin, Bitcoin Cash, Bitcoin SV, and other SHA-256 coins. WhatsMiner M60S supports Scrypt algorithm and mines Litecoin, Dogecoin, and Beldex. For other algorithms (Ethash, KawPow, RandomX), you would need different hardware not in our catalog.
