Information
Profit Information
The BW L21 is currently mining $-1.24 profit a day. The calculations is based on $0.58 income per day from which we deducted $1.82 electricity costs. This means the L21 is able to generate up to $17.51 income per month. After you would deduct the electricity price of $54.72 you will have an estimated profit of $-37.21 per month.
Hint: With our Hosting Plans you will only pay around 0.08 USD per kWh.
If the BTC price reaches $158922 you would earn estimated $-0.95 per day.

More Information
The BW L21 utilizes TSMC's 16nm FinFET semiconductor technology, optimizing power efficiency while maintaining stable hash rates. Unlike many contemporary Scrypt miners, it features a more compact heat sink arrangement, reducing thermal resistance and improving long-term stability under continuous operation. Its firmware includes built-in voltage tuning capabilities, allowing miners to fine-tune power consumption versus performance for different electricity cost scenarios. Additionally, the L21's power supply unit (PSU) requires high-stability output due to its sensitivity to voltage fluctuations, meaning it performs best with industrial-grade power solutions. Its dual-fan cooling system is optimized to balance airflow without excessive turbulence, reducing dust accumulation.
Algorithm Information: Scrypt
Scrypt's memory-hard design was specifically created to be more resistant to brute-force attacks, making it a more secure option for both password protection and mining. The algorithm’s increased memory usage significantly raises the computational resources required for mining, which helps level the playing field by making it harder for ASIC miners to dominate the network. This resistance to ASIC mining promotes decentralization, as more individuals using GPUs can participate, preventing mining power from being concentrated in the hands of a few large mining operations. Scrypt's adoption by Litecoin in 2011 was revolutionary, as it allowed miners with standard hardware to mine effectively, unlike Bitcoin’s SHA-256, which was increasingly dominated by specialized hardware. In addition to its use in cryptocurrencies, Scrypt's memory-intensive nature makes it an ideal choice for securely storing passwords, as it deters brute-force attempts by increasing the time and resources required to crack a hash. This feature of Scrypt allows for the protection of data in environments where password security is a critical concern. Despite its initial resistance to ASIC mining, newer Scrypt-specific ASICs have been developed, but they still require significant resources to produce, which helps maintain some degree of accessibility for miners with GPUs. By making mining accessible to a wider audience, Scrypt enhances the fairness of the network and contributes to a more secure and decentralized blockchain ecosystem. For miners, the ability to use standard GPUs to mine Scrypt-based coins is a significant advantage, allowing for flexibility and scalability in mining operations. You can use our crypto miner profit calculator for Scrypt to assess potential returns, optimizing mining setups based on hardware and network conditions. Ultimately, Scrypt's memory-hard design, combined with its use in both cryptocurrency mining and secure password storage, makes it a versatile and resilient algorithm for various applications.
