I am yet to receive refund, even tho tom claimed he refunded me with false information, only to take it back (claiming mistake) after i notified that's not correct sum nor my refund address.

They have a plant now? when did they get a plant?

Maybe they have a cactus or vikus or something at the office? Cheesy

the big problem that came out these days is da power supply.
5 gh's is using about 36w, how much will be using a 1500 gh's?
a normal power supply wont be able to keep it workin, you'll need to set up a huge supply for that stuff

minirig product design is apparently abandoned, 3.5kw per one household switch is max.

Wrong.
16A * 230V = 3680W maybe but due to PSU efficiency, nature of A/C usual maximum suggested draw is just 80% which is 2944W
As A/C power is a since wave, drawing out 16A @ midpoint of wave is just 150V = 2400W max, PSUs try to optimize to take their power at the sine peaks, but they often miss the mark of their claims, thus D/C operators often recommend 70% of the max, which is 2576W

Just couple posts prior i showed that the actual draw of the device is more like in the 22.6W range. Well, it's actually probably a lot less, i did not count in the PSU idle power.
36W at outlet for a 1250W Corsair ZX PSU which is 80+ Gold, running at practically idle.

lol funny. They missed their target, still the most efficient thing in the works Smiley
This FUD and BFL bashing has gone so funny
46  Bitcoin / Hardware / Re: BFL 5 GH/s Miner Demo on: April 19, 2013, 08:53:45 AM
What is efficiency of 1250W power supply when it delivers only 3% of maximum load?
Below 50%. Kill-A-Watt shows 36W so  power draw of the unit alone is propably 20W. With 25W power supply it should be able to see that kind of figures.
Just saying....

Yea it would be far below 50% most likely, i bet someone can find the power efficiency curve by looking up the model used

EDIT:
Quick googling yielded no tests for below 330W.
But assuming it's even 70% at practically idle the unit is then drawing 22.6W

He asked me to reply to this thread that i would have received a refund, while i have not.
Shortly after that e-mail he sent me a bogus transaction confirmation, with wrong to address etc.

After a while he e-mailed me that he needs to find my order asking AGAIN for order information.
So looks to me like he simply replied refunded hoping i take the bait Sad

I hope i'll be seeing the refund tho.

This is funny. There are many scams, but so far there is nothing to suggest KNC is a scam, infact, quite to the contrary.
...

Then you didn't read the complete bullshit in their very first post:
...
We will in the upcoming weeks opening our order book to allow the purchase of our first set of ASIC miners. They are in the early stages of development now and will be ready in the summer of 2013 (yes in just a few months)
...

So they are a scam because they allow pre-orders? No one is telling you that you have to pre-order.
Many legit companies have pre-orders. Infact anything you buy a ticket for later use is a pre-order, so movie tickets are a scam too?

It's not shame to be fast, albeit that sounds a bit too fast but somehow i doubt it's impossibly fast with skilled people (OrSoC).

EDIT: Just to be clear, i'm not saying either way, only that it is possible this is not a scam so far.

KNC -> legit company
KNC partnering with OrSoC -> Actually needed know-how being used
OrSoC -> legit company in operation for a really long time
OrSoC -> confirms the partnership

All that being said, with all the scams going on i'd be a skeptic too.

Let's just wait they tell us something more.
50  Bitcoin / Hardware / Re: No Asicminer Groupbuy-Thread yet? The auction is running already! on: April 17, 2013, 12:28:11 AM
too much for 10GHs unit, almost better buy GPU at this price, ROI is 3 months, GPU is about that much.

To get 10Ghash out of GPUs, you need about 18-19 7970s at a cost of about 400$ each or 7600$ which is 111btc right now, plus the accompanying hardware, 5 rigs with 1kW-1.2kW PSUs and power circuits capable of handling 5kW + cooling.
51  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: April 06, 2013, 11:29:45 AM
Funny how no one sees

It has been discussed many many times even within this thread.


by the time ASICMINER deploys the extra Thash/s, there's a high possibility that BFL will ship. Avalon batch 2 will ship as well. There are a lot of other players who promise to add more hashrate. All these factors mean that the network will be distributed. The free market takes care of itself.

Assuming the 200 units of avalon batch 2 (it was 200 yes?) ships and is online fully by then it's 13Thash.
If BFL ships by then and 15k chips get online -> by then it adds another 93thash.
But i don't see either of happening by mid-april, maybe late april.

Friedcat: It would awesome if you could post some pics of the setup! Smiley

When was work on the next gen begin and what process will that be?
52  Economy / Services / Re: Gigamining / Teramining on: April 06, 2013, 10:05:50 AM
I still have the opinion that what Giga is doing with this verification claims process is scammy.
It forces people to do stunts to claim them back, making for some people near impossible.

And lots of information i DO NOT want to give out.
Tax identification number -> Social security number.
Photocopies of identification.
All the items required for identity theft.

Even tho that's not the reason gigamining is doing this, i somehow doubt he has top notch security in place to avoid that data being stolen. Again no thanks.

Notarized affidavit: Yeah... I do want to explain to goverment officials wtf is this, and what that paper will stand for, never mind that complication, it costs a lot here.

All of this *BULLSHIT* means all he wanted to do was get rid of as many of us as possible for his own gain.

is that asset list SHA256 in format of:
[email][address]   ie: email@address.com1CAF5612CHMHU...
or [email] [address]
or [email][enter][address] ?
53  Bitcoin / Hardware / Re: BFL RIP OFF... price up 90%, 50GH/s for 2499$. on: April 05, 2013, 08:49:20 PM
Still no confirmation of working bfl ASIC device!

1 satoshi says that people will still be posting this even after all the pre orders have been shipped.

Thumbs up! Smiley
Looks like it.

Albeit one could fake with great effort the current evidence, it's still quite strong. Only BFL track record makes one wonder it's legitimacy.

BKM: Bitcoin returns are indeed insane, but also volatile, high risk, and you need to time your trades for the long term return.
I started with just few euros worth, 350BTC, and all my mining equipment etc. is paid up so far with that return (including BFL FPGAs, and quite a few BFL preorder devices, ASICMINER shares etc.)

But things you are talking about most people don't have a clue about unfortunately.
You are right, margins are somewhat low in the real world. Normal DC accounts HW for 2-3 years return.

If BFL ships these people hating BFL right now will flock to them to get their piece. I have a lot of preorders and i'm anxious too if they will ship.
54  Bitcoin / Hardware / Re: April 3 BFL ASIC update. on: April 05, 2013, 09:30:56 AM
Opentoe:
They also have working prototype(s), atleast according to BFL Josh/Inaba and Luke JR, who is independent developer (BFGMiner)
They indeed have promised to honor the sold hash rate, i would assume they will make it up with Jalapenos or multiple unit shipping. Which actually is good -> Multiple units is higher resiliency. For example if they give 2xLittle SC for those who ordered Single SC, if another fails, you only loose 50% instead of 100% of hash rate.

Dissecting the higher pricing

The effects are multiple fold:
- Early "investors" (ie. preorders, esp. early ones) gets a benefit over others by getting half price units which have higher hash rate (or equivalently multiple units per 1 unit) compared to someone buying today
- That same will also mean that preorder people will have higher returns for longer
- Active miners benefit over others due to current high BTC:USD exchange rate
- High margin might allow BFL to have on-stock products for fast/immediate shipment when backlog has cleared
- High margin also allows budget for starting next gen immediately after current gen is on distribution and backlog fully cleared (which i hope they don't even mention before first wafers are out of fab)
- Downside is network security -> way less units, with way less hash rate will be sold in total
- More downside in network security -> not many are willing to put down 1300$ as their first miner, so entry will be with 250$ Jalapeno not making up that much hash rate relative to other units
- If they go for higher availability with increased margins, newbie miners get online faster Smiley

Now they damn better start shipping within couple of months Smiley

What vouchers are you talking about?

If BFL is a long con, they've put insane amount of effort into it. Especially in the field of even attempting to provide evidence there is progress etc. and other kind of public appearances.

People who ordered in the first month get a discount voucher to "compensate" them for the delay in delivery.  They need to use it within 60 days.  If I recall correctly, it's for 25% of their original order value up to some maximum I can't remember (so if you bought a mini-rig you can't use the discount to get a free single).  I think people who ordered in the second month get a 10% discount.

Where's more info about this?
I did make a order for little single in July ...

Never said i was looking to sell. Never assumed anything about the investor's perspective (daytrading, long term investment, dividend yields or a combination of the above)

I don't see the point in owning non-dividend yielding shares in this setting. Or pretty much at all. If you don't get a share of the spoils - why should i invest Smiley At which point, the current market valuation becomes a simple equation of dividend yield to purchase price, giving % ROI annually.

Disclaimer: I bought my shares ages ago, at IPO price or near IPO prices as part of a diversified investment portfolio. A tiny portion of the dividends so far i've reinvested and bought a few passthroughs, expecting value appreciation even further.




58  Economy / Securities / Re: ASICMINER: Entering the Future of ASIC Mining by Inventing It on: April 02, 2013, 12:05:28 AM
Your calculations are right. But you miss the point that you actually have to OWN (either a share of e.g. ASICMINER or a mining device).

That is why the current price for an ASICMINER share is adequate (or probably pretty much undervalued imho).

I understand that there are limited options right now. It's hard to get an Avalon, BFL doesn't exist yet (nor does 100TH or helveticoin).

However, AM has the same problem. Right now, you OWN ~6.5TH...not 12 or 62 or 262. Understandably, you're anticipating an extra 56TH "soon". Even at 62TH it's still 4.5 BTC/GH. Avalon batch #3 was widely criticized for being overpriced at 1.17 BTC/GH and you could have gotten it "soon" (I think it took more than a day to fully sell out). IMO, 0.7 BTC/share must be for a fairly long term projection (~2 yr)...I can understand that. I can also understand how the share price adds to the value since you can "sell it back" on the open market and maybe even make gains on share price. It's just the uncertainty of the market that I'm wary of...seems like there is potential for a lot of big players to enter the scene and reduce AM's share of the market. Then again AM has a head start on jumping to the next gen (maybe)...



Do the maths about annual gains ... Wildly speculative right now, but just be conservative.
Then add the value of *immediate* access, not months from now.
Then factor in the low entry cost (1 share), and reinvestment of the dividends weekly. There's no greater force than compound interest.

Simple maths really.
59  Bitcoin / Mining / Re: IS THIS SHIT FOR REAL? $10k+ for a pre-order????? on: April 01, 2013, 10:36:24 AM

If your GPUs are running at temperatures that cause the cards to release any kind of smell they're not long for this world  Tongue

In the case of a GPU the air comes into contact with the aluminum and copper heatsink as well as the circuit board to a lesser extent. If breathing air blown over circuit boards was unhealthy datacenters would be deadly to humans  Shocked

Have you ever been to a datacenter? They usually (at least in European ones I saw) have strict rules regarding air conditioning to ensure there is proper humidity and fresh air that doesn't affect hardware longevity.
As for the above I'll addess it soon.

Fully meant to maximize the life time of the hardware, and to maximize reliablity. No other reason those strict rules exist.
Many smaller DCs infact have *no* outside "fresh" air circulation, mostly the same air keeps on moving around. Infact, some shun away because of the heavy requirement on filtration of the incoming air due to dust and other pollutants. You want to keep your servers very clean Smiley
