Now we have launched a new promotion for G-Blade and G-USB miners
https://justasic.com (https://justasic.com)

Also we are now in partnership with MinerEU.com (http://MinerEU.com), the Gridseed official distributor.


We offer IN STOCK Miners ONLY. No pre-orders, No back-orders.

We offer one price for all order size. No complicated tier pricing and combination pricing.

We offer FREE Express shipping (DHL and SF-Express) globally.

We offer Price Match. If other sellers provide genuine offer on the same condition, please let us know.



_________________________________________


 ;D
Howdy,
New Update, we are back with even lower price for USB miners (from $95/unit) and new G-BLADE ($1480/unit)!!   All in stock, ready for FREE shipping.
https://justasic.com/shop/ (https://justasic.com/shop/)
Any other questions? Please send an email to buy@JustASIC.com


Now we offer 1 price for all customers, that is $150 per miner INCLUDING SHIPPING! Yes, that's right, no complicated tier pricing, no confusing different accessories combination price.  

Miners only, with simple ultra low price at $150 each with free shipping!

What's the catch? The only "catch" I can think of is that we only sell the 20 units wholesale box from Gridseed, and also in order to provide a decent price with fast shipping, we have decided to use DHL instead of SF-Express. That means the weight of package has to reach 41kg for us to get a good price from DHL (we pass the saving to you, hence the low price). So the Minimum Order Quantity is now 5 boxes (100 miners)
If customers are willing to pay for shipping on smaller orders, we will think about it.

I am trying my best to be an open and honest gridseed reseller here, if you have any question, even if you have doubts about my business, please feel free to ask.

https://JustASIC.com (https://JustASIC.com) is a very simply online shop  
https://justasic.com/wp-content/uploads/2014/04/JustASIC9.png
We sell our stock at very very very low price (Sorry, please don't ask us for "discount" unless you order 1000+ miners).

$165 per miner (GRIDSEED WHOLESALE PACK, 20 miners per box)

FREE SHIPPING, US ONLY

You order online, pay us using bitcoins or USD via bank transfer (Sorry, we only take bitcoin payment at the moment. If you don't have any, there are tones of websites selling them).

We post the products to you next day with tracking number (Sorry, US customers only at the moment)

...and, if you ask:

Why don't you accept other form of payment? Sorry, our strategy is to minimize our costs in order to provide a good deal. Taking other form of payments require additional costs (fee and labor). And hey, we all have faith in Bitcoin, right? Also, because we need to buy from Gridseed using RMB, and this is not a freely exchangeable currency, that means if we we take too much USD/EURO/AUD/GBP… we will find difficult to convert them to RMB. Gridseed can take USD payment from us now, so we are happy to take USD via bank transfer and Bitcoin.

How long will it take to have them delivered? Sorry, due to the fact that our warehouse is in China, although we use DHL, it will take around 3 working days (we had customers received in 2 days). We will give you a tracking number when it is dispatched. If your order is very large or we are temporarily running out of stock, it may take 2 additional working days. Please note, it will be your liability to pay customs duties and other related fees. However, we can help you to minimize that. So far we don't have any issue sending to the US. If you have special requirements regarding proforma invoice, we can help as well.

How can I make sure this is not a scam?  Hmm...  Sorry, haven't you seen the ugly photo of our stock?  :D well, also you see positive feedbacks in this topic. Our stock is running fast. And here's a video: http://tinypic.com/r/2vt1q10/8 (http://tinypic.com/r/2vt1q10/8)

How can you offer such a low price? Sorry, it's a secret. Or, is it? I believe most of you know that Gridseed price in China is much cheaper that in the US. However, Gridseed only ship to Chinese addresses and they don't take small orders. This is why resellers in the US can enjoy a high margin. We (JustASIC.com) are simply acting as a groupbuyer for groupbuyers. We get good discount from Gridseed, you get cheaper miners, Gridseed sells more, everybody is happy (Except some of our competitors, Sorry).

Do you sell accessories for ASIC miners? Sorry, the short answer is No. Again, we are minimizing our costs, sourcing and shipping accessories will take time and effort. You should be able to find accessories easily on ebay.



https://justasic.com/wp-content/uploads/2014/03/justASICstock.jpg

Now the "new" gridseed wholesale 20-unit box  :(  sorry guys. That's the best I can do for now.
https://justasic.com/wp-content/uploads/2014/03/JustASIC_20minerbox_s.jpg

Can someone else order and take one for the team :)

To be honest with you, that's also exactly what I want.
I know build a trust relationship is not easy. And I know a photo is probably not enough.
That's why we currently deliver 3 units package to the US. This 3 units package is not profitable for us, but we have to start from somewhere.

Just For Information, this is a recent batch from Gridseed, gold color, not the initial unstable version.

Thanks for asking me about the accessories. I do not have plan to sell them soon. I'd rather focus on selling Gridseed miner itself.

Regarding the controllers, I'd recommend to simply buy raspberry pi in the US. Much better than that wiibox control unit.  Also, if you are building a farm, you don't want to use those. You need a PC, at least an atom PC for better USB controllers.

Just ordered a 3 pack of these for $630

Order: #107

Will follow up to this post once I receive tracking number.

Order received around noon (Beijing Time), called courier in an hour, they picked up at 16:48:57
Please check PM for Tracking number.

Tracking recieved

Price list updated.
Still, free shipping to US.

In case people think photos can be modified, here's a video showing remaining stock.

...... Deleted

Regarding the price for the 3 units, I only listed them in order to build trust relationship here. I do not have warehouse in the US, therefore it is not optimal to sell small orders directly to US customers. My target is groupbuyers and mining farm. And I am very confident that I can beat any real quote on same conditions on bulk orders.

I already had members ordered from me. They helped me and I will take care of them. Once they are happy, I will remove the 3-unit and 5-unit packages.

fine I do not want to pick fights in anyway. I will edit my post here.

I have deleted my part as well. 

https://bitcointalk.org/index.php?topic=514603.20

Updated with new price

If possible, I would be interested in 10 units but also 1 ton of bullshit, as I have major aspirations for a vegetable garden this year.

Let me know your offer, thanks

even with 1 ton of bullshit, you still need to wait for them to turn into usable compost  ;D

regarding the 10 units, sorry, for the new batch, gridseed shipped 20-units-in-a-box boxes to me, so I cannot sell individual miners.  :(

https://justasic.com/wp-content/uploads/2014/03/JustASIC_20minerbox_s.jpg

Paypal? :|

I have sent a PM, thanks.

Sorry, I cannot take paypal.
1. they are greedy. my margin on this is already VERY low (I guess some of you know what gridseed wholesale price is, I need to pay for domestic shipping, handling staff and international shipping, those are public information), I cannot afford to use paypal.
2. had someone used a fake credit card and paid via paypal, items shipped, then they charged all the money back. That was 10 years ago, but I decided then, never use paypal as a seller (I still use paypal to buy from ebay etc.)

replied :)

BTW, if you need to build a trust relationship, you can probably check this post:
https://bitcointalk.org/index.php?topic=514603.20
 (https://bitcointalk.org/index.php?topic=514603.20)

i would pay the fees, of course

as for the carder/chargeback protection, they usualy refund you if providing tracking number to them
had some block erupters sold which were paid by stolen accounts - got money back, but took a while

Hi, Could you tell me if SF-Express will deliver to a PO Box? I'm pretty sure I received an Antminer from sf-express to my PO Box, but not 100% sure they were carrier.

If so, I am interested in a 20 box

Was going to buy one... but can only buy 20. No thanks.

Sorry. In my case, of course I provided a tracking number.
But because the credit card company charged the money back from paypal anyway, paypal simply took my money regardless.

Would you ever consider shipping to Canada?

Thanks for asking, but SF-Express does not ship to Canada therefore I cannot ship small orders to Canada.

However, for orders over 21kg (this is the threshold for us to get reasonable price via DHL), I should be able to arrange shipping use DHL.  i.e. You need to order at least two 20-unit boxes.

update, low stock, only 160 miners left.
New batch 1000 miners should arrive on Tuesday 25th March.
Then next batch probably later next week.

https://bitcointalk.org/index.php?topic=514603.0;all

update, all in stock. also we have some accessories as well.

You really need escrow man.  There's no way I'm shelling out money for a 10 pack when you don't have enough credibility.

Thanks for your advice, but no I cannot.  1. additional costs, my margin is already low. 2. risky, if i use bitcoin escrow, the price goes up and down. 3. too much hassle, I think I already have enought credibility:  https://bitcointalk.org/index.php?topic=514603.0;all (https://bitcointalk.org/index.php?topic=514603.0;all)

BTW, we don't sell the 10-pack. Sorry.

price updated

No feedback from members who have been here for long!

Well,  Jr. member and member's feedbacks don't count?
BTW, did you know that I have busted 2 scams and 1 of them were from a Sr. member.

You know screaming SCAM everywhere doesnt mean you are any better. Scrypt hash had issue with a member but it seemed to be worked out.

no, Scrypt-hash has been banned by gridseed and diginforce. 
https://bitcointalk.org/index.php?topic=525965.msg5928387#msg5928387 (https://bitcointalk.org/index.php?topic=525965.msg5928387#msg5928387)

I tried to help people by identifying possible scams.  To you, I was screaming everywhere and doesn't make me any better.   What is your logic?

What is your logic ? Scam is when you take people money and not delivet. Has scrypt hash done that ? What happened to innocent till proven guilty ?

Has scrypthash delivered ?  No
they claim there were official distributor, they lied (Proven by gridseed AND diginforce).
they claim "Bank wire will take 3-10 working days".  I received bank transfers from US normally in 1 day (Fact).
Gridseed and diginforce will not supply to him (Fact), and still, he claim business "as fine as usual" and "more competitive and energetic".
And you still  believe they are "innocent"?  



Is JustASIC honest about everything so far? Yes
Has JustASIC delivered to customers (sameday or nextday dispatch)? Yes & Proven
Have JustASIC customers received their order (DHL or SF-Express)? Yes & Proven
But you believe JustASIC was "screaming SCAM everywhere doesnt mean you are any better".

Are you the police or the prosecutor or the judge ? You're just seller here same with them work for food.

Yes you arent any better screaming SCAM without solid proof is libel and slander. If they're guilty it's being unethical not scamming. Scamming is when they took wire transfer and not deliver. Why don't you pm the guy who posted problem with them. Confirm whether he's being scammed or not, ask him to come forward post in scam accusation. If he's indeed scammed then i will be the moron. And you can be the wiser.

speechless.  It's a big waste of my time.

updated with super low price and new G-Blade Miner

New stock arrived on Friday 25/04/2014

new price updated

You all have access to the new G-Box?  If so, what are you selling them for?

On the first page you claim you pay customs and VAT, how? Do you offer additional discount for countries where VAT is applicable or do you refund already paid VAT by proof with documents? Does it apply to the new prices for G-Blade also?
Thanks

Has anyone ordered from the site and actually got anything?

Warning - last week I received from one Gridseed distributor all dirty units, full of dust, rust under fan blades, dirty boxes. This offer could be the same.
Be carefull.

That's because gridseed pre mines with their hardware. Most manufacturers do this so you usually are getting used "new" hardware.  I've gotten dusty gridseeds and antminers.

I'm keen to find out also, very little info about this seller!

Still looking for signs of anyone successfully purchasing anything from this vendor.

I can't see any signs of life sir!

On a serious note, the prices are almost too good. If we can get some reliable people forward with a testimonial on their experience, I'd be interested in placing some orders!

Ive purchased from JustAsic before when he first started shipping gridseed rounds and all went without a hitch, hes an honest reseller IMO

Cheers for the heads-up. A couple more positive feedback from customers and I'll be interested.

Its $65/gridseed and $940 for Blade(Dual) including shipping.

FYI everyone. Btcfarm.org has them for $950 with Paypal purchasing.  I went ahead and bought one since we're still waiting for confirmations here.  I haven't ordered from btcfarm before but I figure with Paypal, I can always put in a complaint and get my $$ back.

These are not at all profitable or ROI.

I'd ask you to show your work when you make statements like this.

5 Mh of Scrypt mining will make between $18 and $22 a day on a multipool site.
At a cost of $950 these units will ROI in under 60 days.

Even if I am off by a factor of 100% they still ROI in 4 months.

You are totally wrong brother.
First, $18 to $22 is no where there in any multipool.
Second, there is a factor called difficulty which increases "exponentially".
Now run the numbers in a calculator which matter the above.
The result will be no ROI.

Scrypt difficulty is not increasing exponentially.

The mathematical origin of this word has to do with multiplying a number by itself.

If that were the case than a coin with a difficulty of  1000 this month would have a 1,000,000 difficulty were it increasing exponentially

Litecoin has a difficulty of 7126, for it to increase exponentially it would have to reach 50,000,000

There are no scrypt coins whose difficulty is increasing exponentially on a weekly, monthly or yearly basis.

Perhaps the word you were looking for was doubling?

Like I said, I may be wrong, if even by a factor of several times over, but my math shows ROI.

Also you don't mention during what period you say it won't ROI.

So again show your math and prove me wrong.

https://i.imgur.com/8HfBFfg.jpg

here is a calculator showing straight up 5Mh on DOGE

My math shows 4.6 months to break even

$950 divided by $204

DOGE difficulty is falling not rising, so even if it were to double still would break even.

(oh and the number I quoted was my mining 15mh so I forgot to divide by 3 for the 5mh example, in any case it still becomes profitable)

Ok so there are a couple things wrong here.  First you are linearly extrapolating that calculator.  Ie. $204 each month for the next 4.6 months.  That's not a correct way to use a mining calculator.  For example, there will be a lot more hashing power coming online over 4.6 months that will increase the difficulty.  Zeusminer, for example, is saying they will start delivering some serious hashing this month (if they actually come through). 

You also reference doge and the block reward is next scheduled to halve in ~60 days so 4 month profitability isn't going to be constant.  The price would have to double.

I don't have to extrapolate on DOGE if the Difficulty is going DOWN - Forget I mentioned a specific coin. Geez you guys are thick!



So basically I am in a discussion with people who are saying "You are wrong" but have no ability to prove why except anecdotal crap.

I will make it easy for you all to understand.....


Spending $940 on 5Mh of scrypt mining equipment today will get you your money back and then some in the next year.

(hopefully by not mentioning a  coin or specific amount of profit will be enough teflon to keep the naysayers away)


Anyone who responds in this thread without at least an attempt at math is WRONG.

And based on your detailed analysis (the part where YOU do some math) the correct answer is what???

Jeez dude, I'm not trying to be a dick, settle down. 

I never said you were trying to do anything except show how I was wrong, I was not trying to offend you either, if i did I apologize.


This community is (I hope) about mutual assistance and not about telling people they are wrong.

I am not perfect, I wish to be educated.

My attestation is that 5Mh of scrypt mining hardware that costs $940 will recover its own cost and be profitable within a year (probably closer to 6 months) in the right hands.

Using math and charts and trends please someone show me the error of my ways, because otherwise you are not helping me or anyone else in making an educated decision.

I apologize if I implied that you were totally wrong.  I actually agree with you that within a year you should easily ROI.  Mining is definitely up for interpretation.  I just didn't agree with the initial estimate mainly due to the specific example of doge.  The block halving would throw off the initial time of 4.6 months.  No ill will intended though.

http://en.wikipedia.org/wiki/Exponential_growth
The coinwarz calculator you put here don't account for any difficulty change.
It just assumes that the miner will earn the same amount he earns today for ever. That itself is wrong.
Use a good calculator which account for difficulty.
This Dual Blades @ $950 will never ROI. Those who want; try it.

LTC Chart

no worries, we're cool

Brother, it will not. You use a good calculator which account for difficulty. Coinwarz calculator is not accurate. Its good for checking profits for only less than a month or so.

allcoinminer, You are wrong. it will ROI.

If my posts hurt you I apologise. Please see the image I posted above. I was too lazy to put the math I did, sorry about that. We have the calculator ready.
https://bitcointalk.org/index.php?topic=514585.msg6597323#msg6597323

You are still wrong.

You use Litecoin as an example? its the least profitable coin.

What calculator is your screen print from?

yah I used Litecoin. Can you say the reason why I used it? There is a reason. I will tell you here later.
Leave that.
Litecoin is not the least profitable.
As per coinwarz Doge coin is just 2 coins above Litecoin.
But if you check the rates both are almost same. ( Difference is just 0.00000556 for 1mhs and in dollar terms both are same.)
So the calculation will be same of Doge and Lite at this present moment.
You may check the same with doge if you doubt.
And then post here whether it will ROI or Not.

Calculator you used? You didn't mention that (again)

this is getting interesting

The returns will probably much more worse if the announced asics are released on time.

exactly, with difficulty increase 3% (and it could be more with new incoming chips) there is no ROI

Lol  ;D ;D ;D
I was reading all the post then I saw this
I might check this thread regularly ;D

My $0.02

It is my opinion that very few, if not none of the hardware ROI’s, unless you can buy direct at discount and or the virtual currency price is rising. Even being first doesn't work anymore as all the machine producers have been running the new machines long before they are shipped.

5 mh/s for 1000 Bucks? that will never ever ROI. End of Story in latest 30 Days a lot of Big asiscs will hit the Networks and the Diff will Skyrocket. And even this big ASICS will not ROI. (11K for 80 Mh/s... LOL)

I am gonna enjoy this.

also, think about the exchange fees, they are probably not the same for doge or ltc (or btc).
And maybe pick an exchange where you can sell your doge for usd directly.(instead of doge->ltc->btc->usd)

Update:  now have A2BOX in store.

A2BOX (6 module with 8 * 28nm A2 chips each module)
