HyperBit is the Official Worldwide Distributor for the BW-L21 Scrypt ASIC

12, Oct 2017

If you remember a while ago we have talked about the 550 MHS BW-L21 Litecoin (Scrypt) ASIC Miner as an interesting alternative to Bitmain’s AntMiner L3+ Scrypt ASICs. Unfortunately back then these were hard to order as there was a minimum order quantity of 100 units and not an easy and straightforward way to order them. This is apparently about to change as the manufacturer of the devices Biwang Electronic Commerce Co. (BW) has appointed the Australian company Block Assets Limited trading as HyperBit as their Worldwide Retail Distributor for the L21 ASIC miner. So finally some competition for BitMain in the home mining segment and more options for the small miners to get back into the Litecoin mining…

You can currently order the 550 MHS BW-L21 Litecoin ASIC miner from HyperBit at a price of $2690 USD in single unit quantities and get it delivered worldwide with a shipping set to start on 30th of November for the current batch of miners. The L21 is apparently the current leader in terms of performance Litecoin Application Specific Integrated Circuit (ASIC) miner on the market with 550 MHS hashrate and with just 900W of power usage. It is not clear what the situation with the power supply is at this point however, is there one included (no mention), but a PSU does appear on one of the product photos. Most likely you would need to buy the PSU separately, one that does provide at least 1000W of power and comes equipped with at least 6x 6-pin PCI-E power connectors. Do note that all orders are being shipped directly from the manufacturers location – Shenzhen, China.

BW-L21 Scrypt ASIC Specifications:
– Hash rate: 550MH/s (+- 10%)
– Power consumption: 900W (+- 10%)
– Cooling: 2pcs @ 3000 RPM
– Dimensions: 329mm * 127mm * 159mm

550 MHS BW-L21 Litecoin (Scrypt) ASIC Miner

28, Aug 2017

The recent return of interest in Litecoin (LTC) and the growing price has apparently also sparked interest for more up to date ASIC miners and there is one more contender now available apparently. Here comes the BW-L21 Litecoin (Scrypt) ASIC Miner from BW.com promising to deliver up to 550 MHs with 950W of power usage. The ordering process for these devices however is not that easy apparently, there is a minimum order quantity of 100 units and the price is about 2500 USD. You need to contact BW by email in order to arange an order and make the purchase, though with 100 units MOQ this is hardly interesting for small home miners. Bitmain’s AntMiner L3+ Scrypt ASIC miner is still much more attractive to small miners that want to get just one or a couple of units, that is if you manage to buy one when new batches are being released.

BW.com BW-L21 Specifications:
– 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 BW.com
– 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)

Alpha Technology Shows Their First Produced Viper ASIC Chips

13, Oct 2014

Alpha Technology has promised their customers that they will ship this month, October, after the company was unable to deliver by the end of September already. Today the pictures of the first produced Viper ASIC chips have been posted by the company and now they need to start assembling them into the Scrypt miners. And although no date is yet mentioned when they will be able to start shipping Viper Scrypt ASIC miners, it now seems realistic to believe that there is a chance that the first units may start shipping before the end of the month. Alpha Technology has also promised to “also be quickly releasing a video demonstrating our chips hashing as an update to the community”, so we are now waiting to see the first actual Viper unit in action.

Specifications wise the smaller 50 MHS Viper Scrypt ASIC miner and the bigger 250 MHS Viper Scrypt ASIC still look OK compared to other mining hardware already available on the market, though at the prices that they were originally sold you can already buy more powerful hardware in terms of hashrate. The situation with the time required for the Vipers to ROI is very similar to that of the situation with KnCMiner Titan miners – not very likely that it will ever happen, unless the price of LTC does increase quite a bit over the current level. So it will be very interesting to see what will happen with the company if/after it ships all of the pre-ordered miners – will they reduce the prices and continue making and selling the Vipers to new customers, will they be working on new generation of chips or…
