BW-L21 Review – Litecoin (Scrypt) ASIC Miner

Most of us have given up on mining Litecoin since its price wasn’t enough to justify the electricity costs. Whoever kept mining LTC did that in the hope for the coin price to surge once again someday and they were not disappointed. While in January, the coin was valued at only $4 USD, its price surged 20 times in the past 9 months and it is priced $74 today, September 1.

Today we are witnessing Litecoin price peak and experts believe that it is very possible for Litecoin price to rise further and hit the $100 USD mark somewhere in the near future. While no one knows when exactly Litecoin will do that, it is obvious that now is the right time to mine LTC.

BW-L21 Litecoin ASIC

Some weeks ago announced their new Litecoin (Scrypt) ASIC miner – the BW-L21. This new miner is already available for order and it has some rather interesting specs.

Here are the most important numbers: BW-L21 Specs:

  • Litecoin Hash rate: 550 MHS +/- 10%
  • Power consumption: 950 W +/- 10%
  • Power efficiency: 1.727 J / MHS
  • DC voltage input: 12 VDC +/- 5%
  • ASIC chip type: 28nm LTC ASIC chip by
  • ASIC chip quantity per unit (miner): 144 chips
  • Number of hash boards per unit: 4 hash boards
  • Cooling: 2x 120mm x 38mm fan, 3000rpm (front and back, in a push-pull configuration).
  • Weight: 4.8 kg
  • Dimensions: 329mm (L) x 127mm (W) x 159mm (H)

According to this review, the miner was easy to set up; it is also quite silent if we take into consideration its power consumption. The miner does require a PC for the initial setup, after which it works autonomously.

Pricing and Shipping

The BW-L21 ASIC Miner is priced at $2.500 USD per unit. As Litecoin is valued today, the ASIC got a great ROI of only 3 months. The required 1.250 W power supply is included in the box.

Now, the bad news is that the minimum order amount is 100 units. This translates into a $250.000 USD investment.

Those who would like to invest 250 grands in Litecoin mining can preorder the miners today. requires a 50% upfront payment. Once the payment is received, the company promises to start manufacturing the miners for that order. The order is expected to be complete in 3 months, after which the customer will be required to pay the other 50%. Upon receiving the other half of the payment, will ship the units to the customer. headquarters; Source:

Why Litecoin?

Most of you probably know what Litecoin is and why it exists. However, here is some interesting data for those of you who would like to know a bit more about the coin before getting involved into mining it:

  • In some aspects, Litecoin is technologically one step ahead of Bitcoin:
    • Litecoin adopted SegWit way earlier than Bitcoin did, as well as
    • Litecoin might have Lightning Network capability earlier than Bitcoin
  • Litecoin’s 24-hour trade volume is around US $ 1 Billion
    • Its trading volume surpasses the one of Ethereum
  • Consequently, according to, Litecoin “is setting new standards in terms of cryptocurrency scalability
  • According to, Litecoin has an incredibly high market capitalization and it is ranked fourth in the market cap list after Bitcoin, Ethereum and Ripple.

Where to Buy!


In Conclusion

It is needless to say that if small miners like you and me would like to enjoy mining with a BW-L21 Litecoin Miner, we would have to do a group purchase. Talking about which, community members are eventually gathering for one in this thread.

The miner hashrate looks really good, especially considering that Litecoin price might remain above the $70 USD mark for a while. Even if it dips once again, Litecoin is a valuable cryptocurrency and it is not going anywhere, at least while it keeps staying one step ahead of Bitcoin technology-wise.

That being said, some people do not like the way Litecoin is the “testbed for Bitcoin development”. At the end of the day, it all comes to personal preferences and trust.

    anyone interested in starting a group purchase?

    • Cosmic Tino

      Next year .. whole investment for this quarter is gone. Until December im going for the next orders..

  • Cosmic Tino

    Innosilocon A4+ can be ordered also right now. 550mhs @ 750watt. Min order 3 units for something around 1300 bugs..

    • William Wakefield

      How good are they?

      • Cosmic Tino

        hi the A4+ are completely new and right now they are in a testphase.
        the will shipped early @ the mid of oktober. if they are like the current A4@280Mhs devices, so they are very stable too. (hope so 😀 )

        • Tri Nguyen

          don’t let Innosilocon A4+ presale price fool you. the price is for 280mhs, for 550mhs it cost more. i state in their fine print. the final price is calculable base on the final hashrate on Oct 7th. from there website “you preordered A4 280Mhs miner totally N dollars, as we upgraded to A4+ with 550Mhs, your total payment will be (550/280)*N dollars. Your deposit will count towards the total payment.” which mean (550/280) * $1500 = $2952. and their warranty is only 45 days. their btc price is way off compare to USD price in current market so i don’t like the way the doing their business right now. too fishy and shady

  • William Wakefield

    I have purchased a Dash version and only had to buy one unit

  • Eurys Gamez
