How many X-3 units are you keeping for your personal collection?

Bobsag said that when you announced your data center it would be used for the compensation package, that doesn't need to happen anymore so how many units are you guys sticking in there that you refuse to compensate us with, because that's all you can do?

EDIT: what is your current hashrate from the chips that are in now?

Why does it matter how many x3s they will have in their DC?

Did you think they were going to build exactly as many x3s as needed for their rent-a-minion orders and no more?

Seems to me like your just grasping at straws for something to be mad about.

150w @ 120gh/s is 1.25w/gh at the wall (compared to 1w/gh had they hit spec)

Anyways what do you want them to do? Send the chips back to design stage and let us wait another 3 months? I'd rather just get my asic now.

it's almost the same W/Gh ratio as an ant miner wich is cheaper and available now.

Bitmain is 2W/Ghs in NORMAL mode
Blackarrow is 1.25w/Ghs OVERCLOCKED

They mean the Antminer S2, not the S1. The S2 is basically the same thing as one of the X-3 subunits, but has been available for a bit already.

S2 is $2500 for 1th or $2.5/gh

BA is $6000 for 3.6th or $1.7/gh

Thanks david. Do we have the full minion specs yet? 0.92w/gh is not great but its not bad either. Can the chips reach better efficiency by underclocking?

So this is basically going to be a mining stock?

I don't see this working out at all.

Few questions that need answers:

1. The team. Who will run this project? Professionals? Hobbyists? (not talking about just asic designers)

Why should we trust you? This seems like a preorder for a deam asic run by an disgruntled customer with no experience in the field (4 months of research doesn't cut it). Why would we send you our money if professionals fail to deliver 90% of the time?

2. Manufacturing costs. Care to elaborate?

You claim $1.10/gh but that is about as vague as it gets. Is $1.10/gh for a completed machine or just the chip? How much PH must be produced for it to reach $1.10/gh? What is the NRE cost? Wafer cost per GH?

BTW bitmain is already at about $1.25/gh for completed machines.

3. Performance. You claim 0.3-0.175w/gh but where is the evidence to back this up? Who designed the chips and why should we believe their estimations? Has the team made 28nm chips/any chips before? Why have they not tried to sell their design?

What is the chip cost/gh at 0.175w/gh excluding NRE?


Sounds to me like you will be asking the community for 20,000 btc so you can try to produce hardware which will ultimately be too late and too inefficient to be profitable assuming anything materializes at all.

I'd take that bet.

The Monday after by the latest. That's my bet.

jims, sometimes you may sound accurate, but here, either you have s**t in your eyes or you are just getting paid by every single chip manufacturer in the place.

No I just try to not let emotions get in the way of my decision making.

2 month delay is unfortunate but that's about it. Trolls have blown the misfortune way out of proportion.

Why does nobody commend BA for constant detailed weekly updates and the compensation that they were not required to give?

Or thank minersource for doing everything they can to make things right for their customers?

They could have pulled a bfl and delayed for 6+ months with no refunds or compensation but they chose not to because they are not scumbags.

So people are buying this stock and apparently nobody cares that the projections in the prospectus are inaccurate?

Ignoring the fact that difficulty will be probably twice the measly 8% they predict and the fact that they won't get 10gh online by the 15th.

Dividends projections in 1 year add up to less than 100% instead of 200% like advertised.

When you consider realistic difficulty increases we are looking at around 20% ROI in 1 year vs the 200% advertised.

It'd be really stupid of them not to be able to get it online shortly after that if they have a data center and a partner for A2 boxes.

If I had ~1000 Bitcoins, I could probably get about 3GH up by next week without any sort of "Exclusive" contract that they speak of.

Do you really think it is that easy to get 100kw worth of equipment running within a week?

If they had all the working miners in hand I would say it is possible but as far as I know they haven't even been shipped the chips let alone ready to plug in miners.

Anyways even if 10gh is online it doesn't matter because their projections are so inaccurate. They are advertising 10 times what is a realistic return.

WOOHOO, got an email back from minersource about receiving a refund. Still waiting, hopefully it makes it to my wallet! I will edit this when the btc appears in my wallet!

Good thing you complained to the FTC right?

Quote
So we missed every promise and goal we set forth for out investomers, sorry guys. To make up for it here is a buy two get one free sale, but then you need to buy a 50 dollar power supply and cover the shipping cost as well to make your compensation package work. You can't even turn around around and sell the compensation miners because they don't fuckin work.

So missing a single deadline means they missed every single goal and promise?

And not having a power supply means you can't sell the miner?

I find SP10 is much much more reliable and it can reach 0.7W/GH if needed because I see power consumption comparing.

0.7w/gh at the wall tested?

What is the hashrate per chip at that efficiency?

Each machine was built to order, the individualized order for the type of machine and the number of cards.  We did not build a machine before we had a order for it.

Still no explanation for how you got 7600btc divs when they add up to about half that.

Also I find it extremely unlikely that difficulty only doubles when the price of hardware is 1/5th the original price.

Ignoring the extremely optimistic difficulty growth estimations and the fact that it is probably impossible for you to get 10GH online by may 15th, how exactly did you get 7632 btc for dividends? That would be more than 100btc average per week.
1900  Bitcoin / Hardware / Re: [ANN] Spondoolies-Tech launches a new line of ASIC miners - Best W/GH/s ratio on: May 06, 2014, 05:18:50 AM
Lets put it this way:
Unless you are trying to cool a whole 250kw Tank with Novec and 2-phase immersion cooling, it doesn´t make any financial sense.

The only reason why immersion cooling is cheaper than air cooling ist because of scale. When you put many units into these tanks, less liquid is needed and at some point the liquid becomes cheaper than buying heatsinks and fans for your units.

Why would the cost not scale down? Whats preventing you from having the same gallon/kw ratio with a 10kw tub vs a 250kw tub?
-Bulk quantities of liquid are way cheaper. (You get excessive discounts on this stuff if you not only buy 2 gallons, btw one gallon is around 400$ in bulk quantities, if i am not mistaken)

-A small tank is more expensive per volume created than a bigger one

-You need to build a custome lid with air pressure control and access for the water cooled condensers

-You need to build a water cooled chiller and install it in a safe and secure way in your tank.

-The radiator for the chiller needs to be built into an existing structure, i.e. your building in a safe and secure manner and some kind of fan mechanism might be needed
 One time costs of this are far higher per W when only a small radiator is installed.

-A water pump for pumping your water to the outside will need to be installed. Big pumps are way less expensive / waterflow than small ones

-Labor on a small project is far more expensive per kw than on a bigger build.

-Bulk materials purchase is far cheaper per kw cooling in a big build


I could go on. Please admit that building a small immersion cooling rig is far more expensive per kw than a big one.

I agree that large scale is cheaper per kw than small scale but I don't think the difference is so huge.

I think the only significant factor is the bulk discounts especially on the liquid but the fluid is $200/gallon in bulk not $400.

Pumps ($50), fans ($100), radiators($300), and plastic tubs ($50) are all relatively cheap. I would guess that a pressure control system would require ~$100 worth of parts and pluming maybe another $100. So overall less than $1000 before adding the novec costs.
