The Bitmain Antminer S21+ Hyd (319Th) redefines SHA-256 mining efficiency with its class-leading 15 J/Th rating, achieved through a 319Th/s hashrate powered by just 4785W. Developed for the needs of modern Bitcoin data centers, it features an advanced hydro cooling system that reduces acoustic noise to 50dB and maintains consistent performance even under continuous workloads. With its compact design (410 x 170 x 209mm), it is optimized for integration into rack-mounted, space-conscious environments where performance-per-watt is critical.

Profit Information
The Bitmain Antminer S21+ Hyd (319TH) is currently mining $6.90 profit a day. The calculations is based on $16.09 income per day from which we deducted $9.19 electricity costs. This means the Antminer S21+ Hyd is able to generate up to $482.68 income per month. After you would deduct the electricity price of $275.62 you will have an estimated profit of $207.07 per month.
Hint: With our Hosting Plans you will only pay around 0.08 USD per kWh.
If the BTC price reaches $142961 you would earn estimated $14.95 per day.

Algorithm Information: SHA-256
SHA256, part of the SHA-2 (Secure Hash Algorithm 2) family, is one of the most widely used cryptographic hash functions due to its strong security features. Its collision-resistance ensures that finding two different inputs that generate the same hash is computationally infeasible, making it an essential component for maintaining the integrity of data in cryptographic applications, particularly in blockchain technology. In Bitcoin mining, SHA256 serves as the proof-of-work (PoW) mechanism, where miners must solve complex cryptographic puzzles to validate new transactions and add blocks to the blockchain. This process involves miners repeatedly hashing block data with SHA256, modifying inputs until they find a hash that meets the required difficulty level, securing the network against attacks and preventing double-spending. The competitive nature of SHA256-based mining ensures that no single entity can easily control the network, contributing to Bitcoin's decentralized structure. Given its robust security and widespread adoption in the cryptocurrency space, SHA256 plays a crucial role in protecting the integrity of Bitcoin and other blockchain networks that employ it. Although SHA256 requires significant computational power, particularly with the rise of specialized ASIC miners, it remains an essential mechanism for ensuring the security and stability of cryptocurrencies. For miners, the use of SHA256 allows them to contribute to the network’s operation while being incentivized with block rewards. Miners can assess their profitability through our crypto miner profit calculator for SHA256, helping them optimize mining hardware and energy usage for maximum returns. Ultimately, SHA256’s reliability, security, and fundamental role in cryptocurrency mining make it a cornerstone of blockchain technology and a critical factor in digital currency systems.
