Looks like BW (formerly known as LKETC) is coming up with their scrypt ASIC miner, same level of a miner as L3.

Translation:

BW.com L21
Hash rate: 520 Mh/s  +- 5%
Power consumption: 900 W  +5%
Chip process node: 28nm
Price: 14000 yuan (~2030 USD)


Currently for the pre-sale phase, estimated delivery in June

Any thoughts, more info?

We'll see if they mine inside the house or actually even sell some miners to the public.

Maybe there could be a reasonable price group buy for these miners instead of way too overpriced Antminer L3s.

CAD design:

could be intresting there big enough pool to do it, id imagine most of it will go to there pool mining and maybe a small % to joe public. from the looks of it they might even have bought a deal with antminer and just bought the plans and get them made themselves (save alot of money if they do that)

Weird design, wonder if this will see the light of day


Currently pre-sale stage, estimated delivery in June

L21 (LTC Minerals)
Mining Model
520 M ± 5%
Operators force / Taiwan
900 W + 5%
Power / Taiwan
14000 Yuan
Price / Taiwan
28 NM
Chip technology

Note:

1, B21 200 Taiwan from the sale, B11 and B11 Plus 500 units from the sale; the more buy, the more discount incentives;

2, L21 (LTC Minerals) only pay 7000 yuan as a mining machine 50% of each deposit, etc. make up the remaining 50% balance before mining machine can be shipped out.

Unless we get some huge group buy discounts this won't be great at all for most of the world. BW is charging way more for a miner that is supposedly the same as the L3+ in terms of hashing. Backside fan design is quite interesting, haven't seen anything like it to this day. Looks like there's a carrying handle for moving your miners around on top too

Due date for this?

Is June.  But June 30 or June 1.

And does bitmain simply knock heads with this company.

Years ago I got sucked in with grid seed blades.

Seems to me it could happen again.

The preorder asic purchase is getting very hot now.

I think there are millions of dollars  in script and X11 .

The summer will be nuts

This stuff is popping out of the woodwork again like they did a few years ago with pre orders... seems like people have forgotten.

I might stay away from the scrypt ASICs, as when tons of these AND Antminer L3's enter the market, the Litecoin difficulty spike will be huge.

Already spiked huge this past month and growing. Easily 300k diff next month and 500-600k diff by the next batch of L3+ delivery.
This vaporware is DOA.

[HagssFIN]

I don't think this is vaporware, but BW might keep them mining in the house and not sell any to public market.

[Longsnowsm]

As soon as profitability gets too thin these miners will "vanish" as everyone looks for a better place to invest their money.  It looks like that is going to happen pretty quickly this summer.

been hearing more noise on these..but no price

likely will go for internal use...

would be nice if they made a run at bitmain and were competitive thou

They posted in Twitter more about this miner.
Miner looks pretty much the same as in the previous CAD drawing but there is no handle on top to carry the miner around

At minimum , the prospect of using short 6 Pin PCI off older rev HP1200 breakouts to the top jacks could allow for a neat "bundle". Not surprised to see more Scrypt , the BitMain sales were off the chart.

[ayoungtech]

I contacted them through Facebook, asking for more information. They responded: "Hello, Here is the information on the LTC miner. The price is $2800 and minimum purchase is 100 units"

[HagssFIN]

Ok, so the price is up a little.

I'm not so surprised that they don't do small orders but only big 100+ bulk orders for big customers.

[Longsnowsm]

I am just waiting for the vultures to come along here shortly and offer to setup a group buy for $5600 each... As a "community service" of course... 

Sadly I really dislike some of the things I see happen here in our community.  It is pretty sad.  Not sure there is enough demand here on the forum to swing a 100 unit order.

$2800 per unit? That's far more expensive than the L3+, and you have to purchase in bulk too.

[Longsnowsm]

I think that is still lower than the going rate to buy one on hashnest right now.  So that is likely what they are aiming at is the more immediate buying scenario.  Not setting up pre-orders for "Christmas 2017" LOL

Ah yeah I wasn't looking at hashnest but the batch of L3+ miners from Bitmain directly that just sold out for $1300 per. Sure they don't ship until late August/September, but so long as the price continues to rise along with the difficulty profits should still look just as attractive by then, especially with Charlie Lee back on LTC full time.

Well that is the double edged sword... We don't know what will happen and if you spend your money today for a miner in September and the bottom falls out or goes flat then what would earn you good money today may not be very good money by then.  Oh and there are no refunds at Bitmain, so you pay for it and the deal is finished.  So it is risky.  So that is why you pay the big bucks if you want a miner soon, and not as big bucks if you are willing to "bet" on the future.  

Just as fast as these cryptos have gone up they can and will go down.  Also if you wanted in on the Aug/Sept batch that is sold out so there are lots of people placing their bets.  Let's just hope it pays off or be prepared to grind it out if the profits vanish and we are back to making $4-5 a day per miner if we are lucky.  Hope for the best and prepare for the worst.  

So this is why the LN21 might be interesting.  You have to compare apples to apples as far as what and when.
