Frequently Asked Questions
The Bitmain Antminer S21 features cooling based on fans and airflow. Air cooling setups require high-volume ventilation and heavy-duty power cables rated at least 2.5 mm².. To initiate mining, plug in the LAN cable, scan your local network for the miner's IP using an ASIC Tool, open the web dashboard, and enter your target pool stratum addresses.
Currently, the best available price for the Bitmain Antminer S21 151Th/s ASIC miner on our platform is 931 USDT. This listing is provided by IBMM Technology. You can review all current listings, evaluate supplier credibility using our Trust Factor badge, and proceed with a secure deal inside our catalog.
Upon conversion, the computing power of 151 Terahash/s is equivalent to 151 000 000 000 000 hash/s, 151 000 000 000 kilohash/s, 151 000 000 Megahash/s, 151 000 Gigahash/s, 0,15 Petahash/s. Depending on the coin algorithm, the baseline operational output denomination might be displayed in different network standards. To quickly convert any hashrate, solution, or graph volumes without manual calculations, use our dedicated hashrate converter tool on the TrustMining website.
Given the current network difficulty of 132,716,002,350,731 and a block reward of 3.125 BTC, a single Bitmain Antminer S21 151 Th/s will take approximately 13797 days to successfully secure 1 full Bitcoin. The device yields roughly 0.00007248 BTC or 7248 satoshi per day on average.
The Antminer S21 rig is exceptionally data-efficient, utilizing only about 50 to 150 MB of network data per month per machine, as it only sends small textual cryptographic shares (work updates) to the pool server. The core requirement is connection stability and minimal network latency rather than raw speed (Ping to the pool under 50-80 ms). ASICs must be connected exclusively via a **wired LAN cable** (Ethernet).
If adequate cooling is maintained (ASIC chips under 75-80°C), dust is cleared regularly (every 6 months), and grid voltage stays stable, the Antminer S21 can operate reliably for **3 to 5 years**. The most common components requiring eventual routine replacement are cooling fans.
