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.

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 

[philipma1957]

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.

[HagssFIN]

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.

[MachineZero]

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.

[GMPoison]

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"

$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.

[wheelz1200]

Would just rather buy some second hand L3+s which are real at this point and have shown to be a good design.  $2800 and a min order of 100 is a no go.  Sorry but will stick with the L3s i have and ride em out.  If these do come out might have some worries about my titans though...  

[Longsnowsm]

I don't see a performance advantage with the L21, it would just come down to availability and maybe some competition for Bitmain.  Bitmain has started the game of selling stuff way into the future, well if another company comes along and offers real miners in hand now then maybe some of those "pre-sales" start to dry up. 

I welcome the competition.  I hope it turns into a horse race so we have choices.  So far the 2800 and 100 unit minimum isn't going to do that.  They clearly are focused on the "big boys" who are filling data centers. 

[QuintLeo]

At least it looks like they might actually sell some of these units, as opposed to their Bitcoin mining units that never did end up going on sale to the public.
Specs are inferior to the L3+, but quite close for a 28nm unit vs the L3+ apparently being 14/16nm.

Price though - they better be ready to drop it FAST once Bitmain gets close to shipping their next batch.

 Given what I've seen dealers selling the L3+ for right now though, they MIGHT get some sales.

 Hopefully it will also pressure Innosilicon to drop their INFLATED pricing on the A4.

They probably will lower the 100 unit bulk rate to something more manageable to move them in China to big data halls. I doubt they have the
chops to compete against bitmain in retail price per unit ...etc

ie bulk 100 sales NOW is still like 2weeks or more before bitmain stuff ships..thus the extra they are charging if they are going out the door now
may be moot to a large buying in china vs getting bitmain stuff on an order now in sept or oct

i probably don't know what I'm talking about...but used to see what I thought was high priced 100 priced lots of btc equip in china more at those prices
back in the day in bulk..but the stuff was usually dumped when the more/bigger/competitive bigger player manufacturer was not shipping for a month or so.

makes a diff in my view if you are a big player putting stuff up NOW vs 2 months later at less price

anyway ..just a guess on their 100 unit price being high..its on hand .thus a big player or more in china at 2-5c elec will grab it up imho

want to be wrong and have someone slap around bitmain on price and delivery....don't see it happening yet thou

Well Bitmain just released another batch of L3+ but now the price is around $2000. Still fair for the potential profits that these things will make though. I wish BW would sell less than 100 at a time so there would be some more competition out there.

 Delivery mid-to-late September - and priced in Litecoin, which is a change for them but does make SOME sense.
 They had that batch up yesterday, but it was priced originally in $ - unfortunately I didn't pay close attention to how much $, so I dunno if they jacked the price when they changed to the Litecoin pricing or not.

They must have high hopes for LTC price. Now the preferred way of receiving payment for L3+.
Glad I got my order in last week.

I have high hopes for the future of LTC. Altcoins are making big moves, and LTC is no exception with all of the positive things that are going on with it.

[kurbeks]

Would be interested in few units if someone would do group buy.

[GMPoison]

Would be interested in few units if someone would do group buy.

Group buy of 100 wouldn't be a bad idea, we would just need at least 100 units ordered or none of them would go through. That's also a lot of money to handle.

[Longsnowsm]

Well I would suggest that the first step would be to reach out to manufacturer and see if they are open to a group buy if we could get a large enough order.  They may be willing to help the community with such a purchase.

Secondly I would only suggest doing this if the manufacturer was the one accepting the orders and the money for the orders, or some sort of escrow which is pretty unlikely to happen given the size of the order.  Most of the escrows are not going to want to handle that much cash.

The logistics of such an order could be a nightmare.  If the manufacturer will drop ship to individual addresses then it might work.  Otherwise you have to send the miners to a single receiving point and have them forwarded which means even more shipping costs added on, and the possibility that the order ends up getting hung up in customs and a large customs fee is tacked on due to the size of the shipment.  And of course you would need to trust the receiver with you equipment to send it onto you.

You would need to trust the manufacturer with your funds and hope that they will deliver the product.  It is less risk with a company with a track history like Innosilicon, so I don't know how much trust you can place in BW.

If I were more interested in buying some of these I would offer to try and get a group buy going for these, but I am going to beg off on this one.  I have the feeling Bitmain has already taken enough orders to flood the market with miners so I think I am going to wait and see what happens next.  I will be monitoring this thread with interest in how this turns out.

Yeah, you bring up a lot of problems which are all logistical that make sense. I don't know how group buys have been done in the past but I'm assuming someone (or multiple people) that have proven themselves to be extremely trustworthy would hold the coins until the bulk order is to be made, then receive all of the miners and reship them to their respective owners. I wouldn't think that the manufacturer would have anything to do with it (nor would they be willing to) and it's all done by the leader of the group buy.

[Longsnowsm]

I coordinated a group buy in the past with Innosilicon and they helped me to facilitate the purchase for the community.  We were able to get them to reduce the minimum order and they were willing to direct ship to us as long as we ordered at least 3-5 miners.  So that worked out pretty well.  So the manufacturer may be willing to help.  Don't rule it out until they tell you they can't do it. 

Also you have to think about what it would be like to get an order of 100 miners and then have to keep track of who ordered what and juggle shipments and assume the risk of possible damage.  It would be a pretty large undertaking and not something that many people will take on unless they are going to charge you something for doing all that work.

Small orders not as big a problem, but 100 units?  That is a lot. 

[kilo17]

I have emailed them but not gotten a reply from them yet.

[Searing]

Well the odds got better. Bitmain raised the price of their L3+ to 41 LTC (only crypto listed..I assume you can still wire xfer)..that currently is about $2,100 usd.

Great evil planning on their part. IF LTC goes to 75 bucks, bitmain will point to them and say buy now..if LTC Price dumps to 40 bucks they will say

buy now great deals.

A way to maximize the most amount of miners out the door with the least amount of hassle on their part..self-regulating to get max units (er toasters) out the door...L3's that is

So

2,800 bucks now for an L21 miner from bw.com is looking a LOT better if they

1) have them on hand to ship now vs waiting till end of Sept or beginning of Oct to get the above-mentioned batches of L3+'s

2) if you can find a legit guy doing a group buy like (longsnowsm) to do it, assuming they will take pity on hobby thread here and do a batch of 25 say at that price


The main reason for them to do so ..is to get the word out to the big boys on this thread that COULD with like 4 whale buddies get 100 piece lots

Group buys can really take off under the right circumstances

but anyway, those are the two levers you'd have to move to get this big a*ss rock moving and get some of these out into the world imho

edit:

should and one more point

3) They have to answer their emails to either a) consider this group buy or b) tell us to bugger off

I just contacted BW and proposed a buy and review for one BW L21 Litecoin miner (like I have done previously with Hotmine company).
I know it is way below the MOQ of 100 units, but let's see what is their answer

I got an answer from BW.
Let's see if I will have a review about BW L21 for you in August. 

[Truthchanter]

any news?

[HagssFIN]

They told me that the August batch is coming next and to be in contact with them near August.

[kurbeks]

It's near August now

[HagssFIN]

Yeah. I'm moving forward with the buying process at the moment.
I will start a new review thread here as soon as I have it and have had a proper look at it.

There is now a short introduction video for the BW-L21 Litecoin miner.
It is pretty good video with lots of info, but the guy keeps mixing electrical units in wrong places (volts, watts, kilowatts etc.).  
Video: https://www.facebook.com/BWCOM1/videos/1207481296022406/

Top three new information from the video:
1. price is 2500USD including a PSU
2. minimum order quantity is 100 units
3. delivery is after three months you make the order

 You appear to have a fairly high electric rate (I'm guessing 7-8 cents / kwh based on your "electric cost per day").

 I'd also estimate that you're using a "difficulty increase" factor that's a little on the too high side, but that MIGHT change if BW.com can get a significant number of these miners built (on top of the existing Bitmain L3+ and Innosilicon A4 production).

1. You and as all these calc assume that only diff will go up but price won't follow.
2. You can mine more profitable coins than LTC with this.

I made the payment today for 1x BW-L21 miner, now it is just up to UPS   DHL when I can get a good look at it and do the review thread.  
It is probably going to be next weeks tuesday or wednesday.

[Inka-mining]

In 4-5 days i receive 2 L21 in the european datacenter for testing. I will upload pics and info about hashing power.
Our COO was in hong kong doing shooping .... some antminers, avalons and L21 

[HagssFIN]

Cool. 
Then there is at least two of us to tell more about mining with the L21.

[Bulletdodger]

Can this be bought? Like right now?

Or same as Bitmain, waiting for a few months?

yeah but last I heard they want 2,500 bucks....so that is iffy, imho vs an L3+ say in bitmain's next lot

Some of this stuff is just too close to call on ordering..now if they were the same price...well then they likely could clean up beating bitmain

at least for that batch

[kurbeks]

Bitmain is 2K. So it's not that far off, if they can ship before Bitmain does. At least if it's few weeks before.

already betting on bitmain D3 x11 miner arriving 2 weeks before the rest of the other 5 Mfg's x11 dump in October

thus .....really not sure that was the right move (ack! if they are late)

so roi on that unit will likely depend if I do beat the 2 weeks with those x11 d3 units

again....a hard way to bet....on companies estimated timeline

better probably just to keep your coin and hold imho

whatever the asic flavor on such games...we may be too late into the year now for it to make any sense

I have a large batch of L21 coming end Sept, I might be willing to let some go to grow my network with big miners who would like to try them. PM me for info. P.S their pricing includes PSU and its faster hash than l3+, you cannot compare the two.

 520 vs 504 official hash rates, 900 watts vs 800 watts official rated power usages.
 They're VERY close and definitely comparable units - much more so than the Bitmain S9 vs the Avalon 741 or any of the Bitfury-based machines that have been announced to date.

 The big question is going to be "is the RELIABILITY better than recent Bitmain products" (which has been poor since the S7).
 LKetc had a good track record there, but there haven't been enough BW.com units seen in the wilds to judge that yet.

 The 100 min order thing though is a KILLER for most miners.

[wheelz1200]

If the minimum order quantity is 100 does anyone know about how many of those batches there are?  Thats a lot of hash coming online right with bitmains L3s and their monthly batches

[kurbeks]

They just make these miners for themselves. And only selling to pesants like us to get money to order more chips for miners. Problem would be that they probably will want single payment for those 100 miners (Group buy), instead of each pay for their own miner.

520 is not correct, recheck

[rummy]

Ships at 550 mhs from china

But can change to 600 mhs

They actually manufacturer the chips for 600

[HagssFIN]

I'm almost ready with my review/guide for the BW-L21 miner.
I will probably have it ready and released at tomorrow in Friday.

[jwchong]

looking forward to your review soon. thanks.

[kurbeks]

looking forward to your review soon. thanks.

+1 to that and then group buy

[HagssFIN]

The review can now be seen in this thread https://bitcointalk.org/index.php?topic=2118409.0
Let me know your comments. 

[Inka-mining]

OK First batch of machines are here.
First impression, very good.
3 days running, 550-570 MH  range.
Very good cooling. Not so loud.

Some pictures:

I give the miner 8/10 ... for now.

In a few weeks maybe increase/decrease the number

 

[Bulletdodger]

Minimum order is 100 pieces? If I got that right from the FB page.

If that's the case, anybody interested in a group buy?
I'd get 10 to 20 of them.

Thanks

Yeah, you need someone to do a group buy.
But it is not that impossible if there is from 3 to 5 guys that want 10 to 20 pieces and then like 10-20 guys that want less quantity.

So guys, please either PM me, or reply here who wants to participate in the group order.


PS, can these be overclocked?
Thanks

[HagssFIN]

I haven't tried yet as I'm keeping it at the 684M frequency as it was delivered and the hash rate is a decent 570-580Mh/s.

[LTCbusiness]

To be honest, the price of $2500 is about 46% higher than the L3+ one ($1650 +$62.5 PSU), with 10% better hashrate, the  opportunity cost is about 31.3%

The most problem is BW need 3 months to ship this miner, which is about around Dec.

[Freight]

I'm interested in purchasing, depending on price.

[bclcjunkie]

this.. so i went with bitmain.. in case they can deliver as soon as order has been paid then count me in. i'll consider getting around 10+

[solisgod]

I would defo be interested group buy depending on price and delivery date.

[atropoulos]

Interested in participating in the group buy for a few units.

[trackers]

Not sure the price is justified unless they were delivering units before Bitmain (which it appears they're not)

[Marvell2]

Im in for 5

[Inka-mining]

So far 75 Units on, only one with 1 asic card at 30%,  42-45 GH LTC with good temperature.
Excent profit. Tomorrow finished the setup of the other 25

and how exactly do we tell if you are legit with a newbie account?

my status here is legendary with a good trust rating...send me ONE and I'll review it and pay you for it after it arrives..thus establishing trust

if you don't prefer me others on here can be the same

philipma1957

longsnowsm

Maxumark

Searing (me)

others?

But right now with a newbie account with out someone on here with a decent trust rating and account standing....too many scammers on bitointalk its just
not gonna fly imho people sending BTC or LTC to a random newbie account

you have to establish you are legit first..again not a slam..just the way it works on here with scammer newbie accounts trying the same every other day

again ..ask around...this is a common method to see if a piece of equipment exists or is vaporware

Thanks for your feedback, I appreciate your concerns. If you want to get some machines before we launch our site, I can offer a solution to verify. Contact BW directly (bw.com) and ask them for their distributors email, or whether they know who I am. Just offering the opportunity early as I am aware the interest there has been here from the members of this group.

again..anyone can get on that list (hell, I'm on that list) does no good for the numbers they want in my case...can't afford in bulk

proof is in the pudding ..again you are likely legit..but no way I'd take a chance with your bitcointalk newbie status

it is the only work around I know to your problem...find someone on here with decent trust rating (see my prev post( hint: me, me) lol)

send unit..trusted bitcoin guy reviews unit...pays after the fact.. and you have your status verified by a trusted member on here actually getting unit and paying after the fact
as proof of concept

not sure how else you could do this (paypal?) but w/o cred on here with newbie status will be a long, slow haul imho

good luck regardless, just how it flows with the never ending newbie scams on bitcointalk (see the bitmain thread as an example) your gonna find it slow going

later

[Searing]

Well...the problem is...not very many folk on here will send you $$$ w/o a legit email or announce on bw.com of your legitness as it were....

IF that is cloudy..then some newbies will buy your product....and if you are legit announce such on thread here..the old hands will still avoid your product

and newbie accounts saying they got your product and you being a newbie account ...has no weight on here

thus again..not a slam..if you are legit you wasted a month getting cred on here when you could have moved product

and again this is NOT a plug by me to get a unit...philipma1957 has done such reviews and paid afterward. The guy who did the review from bw.com on this thread

paid after I believe also ..it is common.....I think longsnowsm on the original A4 unit group buy it was the same

pick your person on bitcointalk to do such to move this process along

but again..just being the official distributor on bw.com is helpful..but someone has to jump and get some first...that may take a bit on here w/o some more trusted

members like philipma1957 etc backing your play..you lose a month of sales while your trustworthness is verified (slowly imho)

thus how philipma1957 and longsnowsm etc were able to participate in group buys and/or review a product

(hey ..its just like the celebrities on the shopping network)

anyway good luck...I'm golden for product....so not a big deal...was bored willing to do a review ...but there are plenty of others on here

that would say you face the same bottleneck on being trusted and such....losing time (imho a month) while it got sorted out that folk COULD

get units thru you..)

anyway ask the other guys I listed as options for advice...you have mine

It's not like they read this thread. Or they would have replied to a 💯 order 6 weeks
ago, when practical. Thus my assumption big player and big orders in  China 🇨🇳,
But no real game outside of China. Now at these prices and my assumption of the same attitude for

warranty and tech support, assuming you could even get one unit, consider me unimpressed at
this point in time.

On the other hand....Bitmain sold out of L3+'s again (2 hr notice was 4am CST USA) at $2,280 usd last nite it was

so consider me befuddled at those prices selling out units and there are at least now 4 more batches out in the world

just from bitmain that I can figure.....so say another 40k to 80k of units in the wind now...

thus we need a pretty good price pump (at least 1/3 imho) or this will turn to muck by the end

of the year ...earnings wise that is

anyway....I've not a clue on why people are buying these at these prices...

on a positive note..adoption of crypto has to be driving this..it has to be newbies thinking the price of crypto will rise

at least if that is true...adoption is way, way up....I can't see any of us in this for a bit looking at difficulty rushing off and

getting any asic equip of any flavor for the price the Mfg's are charging now

not to mention they keep selling out

so hell..perhaps the newbies buying this stuff will act as cheerleaders and drive the price of crypto up

but it is gonna take a lot more than I expect (color me cynical)

whatever....am reverting back to utterly confused mode...I've not a clue

Basically a combination of Fear of Missing Out, plus people not in the know see people get millionaires and just randomly buy into hardware hoping they'll be millionaires too. The lack of availabilty with Bitmain drives that fear up too, eventually people will find out that buying extra coins would've been a better investment. Like I found out after going for gridseeds in 2014

[rummy]

At 600 Mh/s thats like one free l3+ for every five ordered. Even at a lowly $20 dollars a day profits and a high purchase price of $2800 you can still make roi in 4 months or 140 days. I bought five of them, I'll let you know how it goes.

[rummy]

Just checking back in, looks like this post has died.lol Anyway they have been delivered and are set up and running. Five miners running at 586 Mh/s - Id post a few pictures but I don't think it will let me. Any question I can try to answer.

You will need to look at the shipping/packing manifest that was provided to Customs.  If you purchased them through Hyperbit, there's no telling what they listed the product as on the forms.  One person I know saw that Hyperbit had listed the miners as "baby napkins."  So, they are asking you for conformity papers - but conformity papers for what?  What product code?  Then, you can go to step 2, which would depend on product code, etc.
