Topic: BW.com L21 - Litecoin (scrypt) ASIC miner - unofficial speculation thread - page 4. (Read 15143 times)

Can this be bought? Like right now?

Or same as Bitmain, waiting for a few months?

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

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 

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.

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.

 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).

ive got a guy in my area selling these and ..

all the maths ive done suggests buying one of these for LTC will never make positive ROI, what gives? why are you getting excited, what have i missed?

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

It's near August now

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

any news?

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

I contacted them on same 2 weeks ago. They have not replied.

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  

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

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. 

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.

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.

 

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.
