I may do once chips are in their hands and proven to exist. Until which point I'm still the scum of the earth according to this forum. I'd be damned if I did, and damned if I didn't. I'd personally prefer the lesser of two evils and wait before adding any kind of reseller link for myself. The abuse is just not worth it. I'm sure if everything work out as planned there will still be reasons to demonise me. I actually kind of regret going if I'm honest.

When I asked about this when they first announced a hosting solution, they said they would host in October

They indicate on their website that the hosted units will be hashing within 1 hour (or so) of being finished at the factory.  I assume this timing to be non material to the decision.

When I spoke with him today he made a remark: "It's good you did a research", which most people don't do

Still I don't see a reason why you souldn't register as a reseller
It's free

Because of all the BS associated with attending a fricking openday (something I offed to do for more than one other company prior when I thought they may be a scam), Coupled with the belief that somehow as I got off my ass and asked questions others here wrote (we spent the week or two before compiling q's here from members) I'm either a shill, some rogue agent provocoteur for the government talking down Bitcoin in place of BTC, or on the payroll of Visa or Mcard I personally don't think it's right that I'm in line of any kind of payment or be seen promoting for reward until such point that the company makes good on it's word. I'm not a paid promoter. I never was a paid promoter, and I may only consider being paid if something tangible exists to promote. So perhaps after they have a chip I'll get my feet wet there. It's an integrity thing.

That said with a reward of 1 unit for every 10 sold, I'd live to know how many I've helped in the decision process, and what size those orders were, although at no point have I told anyone to buy anything, and I have strictly said to use anything I wrote in addition to your own research. Sensible advice, but having seen this recent affiliate offer I certainly wouldn't turn down being acknowledged for my effort in due course. However I went off my own steam, for my own agenda, to determine whether I wanted to part with my own cash on this. I was vocal before, so it was the logical thing to give feedback to people, what I don't understand is why no one has done this elsewhere. We had Daggeteo write words here in the week before I went. And we've had a guy a Terrahash, Knightlife write a report with pictures. It seems logical, but people prefer to sit and bark accusations at those that do instead. Still that's the lowest common denominator in the scheme of things. If you're buying and helped either tell Sam or Andreas I helped, maybe they'll keep a tally, or tip me a drink in the addy below.  You've been one of the few that followed through and made some calls prior to make sure you're behaving responsibly before purchasing anything here, so good luck bud

anything you can share with us?

Call and ask

I just got off the phone with Sam and he was really helpful and gave me answers to all my questions
So don't be shy and call if you have questions

Shame you didn't ask how long to get it hashing if hosted. That's got to take some time, they arent hosted at the factory and need setting up when they get to the hosting facility. Hard to compare without knowing that.

Bitcoinorama, why don't you register as a reseller?
I'll be ordering 2 Jupiters soon and to be honest there's no one I feel I can trust.
I wrote to John K, Graet, theymos and Gavin, but nothing

Yeah that guy had also announced to the world how rich he was through Bitcoin, his name and where he lived.

He then followed it up by selling his Porsche for Bitcoin and basking in the press again stating how rich he was, what his name was and where he lived.

He then promptly told everyone about his Avalon printing press. He may as well have left the door open to be fair. People need to use some common sense. If these were jewellery boxes you wouldn't tell all who would listed what you had and where you kept it, now would you?

I was trying to figure out if it was more financially attractive to do the hosting option for the Jupiter I ordered and decided to send them an e-mail:


Just got an e-mail back from KNC


Doing some rough math, If KNC ships around the end of September, a 400gh/s unit will be producing around 2 bitcoins per day at a difficulty of around 100mm.

If it takes 4 days to get the device, I will have lost out on 800$ USD (equiv of worst case scenario of mining opportunity cost).  I'll also have to buy a power supply and pay for electricity, which will amount to about 400 bucks over the 6 months.

Therefore, I figure the risk premium associated with hosting is about 1k to get the peace of mind of 24/7 hashing.  Does anyone have any thoughts that would help me decide one way or the other?

There will be for sure a lot of fun in the KnC lab!

They stated at the open day, that they will not do any classical ASIC production tests (neither wafer test nor final test). If this is still true, it means they will package the dies and put the resulting chips on the PCBs blind.
If the chips work at all and at which speed they probably can determine by running a complete miner only. In worst case this can result in tweaking each box individually.

That is true. The timing models and static timing analysis of the ASIC's are very accurate. But they are given at a certain power supply level and temperature. If you mess up your mechanical, thermal and PSU design so these conditions are not satisfied then you're pretty much screwed.

However, if you then start to test your system and push the margins you will be screwed again since you don't know where in the process window the particular chip you have in the lab is. If it's a best case device then your systems might fail when you get a new batch of ASIC's which are not best case. Your production line will halt and you have to start debugging again. Or even worse, if your production test is not optimal you will not notice until customers starts to complain and return your product.

BFL was way off, and Bitfury's chips also ended up using more power then expected. And, of course if the power draw is too high, then you have to do things like reduce the clock speed/voltage in order to keep it cool. It's reasonable to give yourself some design margin since other bitcoin ASICs have used more power then anticipated.

So, I'm sure they have an expected value, but they won't know if their simulations are correct until the chips arrive, and if you say "our chip uses x Watts" and design the system around that, and you're wrong, then you're fucked (that's what happened to BFL, all their fans/PSUs didn't work)

Actually you do know the performance of the chip before it's made.

The ASIC vendor will give you timing models and you run static timing analysis on your design and it will tell you the critical path and how fast the device will operate.

However, in most cases the produced device will be faster than the spec. Hence it's possible to overclock the device. But you have no guarantee that the next batch of devices will be as fast, it might be slower, or it might be even faster.

As for thermal they should have a pretty good idea. You try to run a worst case simulation where you generate a VCD file which will show how all the nets in the chip is toggling. Then you run this through some power estimation tool (given a specific package) given by the vendor. This is not 100% accurate and depends on how representative the VCD file is for your worst case. But it gives you a pretty good estimate. Then there are tools to simulate the thermal characteristics of your mechanical system.

lol at the last line

I live in a country where some people would kill me for the platinum in my mouth.

Land of the Free, Home of the Brave.

Honestly if I was purchasing several of these (or any other manufacturer's offerings) I wouldn't be as concerned with "smash-and-grab" criminals as I would be intelligent, computer(and BTC)-savvy burglars that had already determined how many miners I was likely to have.
I would add cheap GPS tracking to each chassis (like GPStogo or something similar)
I added GPS tracking long ago to anything expensive I value (tool boxes, vehicles, high end PCs and AV gear, etc)

As far as keeping your unit from getting Stolen get a fake laser security system to scare off thieves.

I doubt thieves would steal it unless they knew what it was.  Someone breaking into a house is going to want to go for stuff that's 1) Expensive and easy to sell and 2) light and easy to carry.

On the other hand if they do know what it is, they will obviously go for it right away (depending on the difficulty)

GPS tracking could make it pretty easy for the government to confiscate them if they ever decided to ban bitcoin mining

Probably the best thing to do would be to get home-owners/renters insurance and insure it for $40k or whatever you think you'll ROI in it's lifetime.

You're right.  It's not important.

But other then that of course they don't know what the final specs will be.  They won't know that until the chips are done. It depends on the yield as far as the hasher engines.  It depends on thermal output. It depends on a lot of things. Avalon chips are actually underclocked and undervolted, presumably to help with cooling and power, yet they perform 36-40% better then what they were advertized as. .  That's because Bitsyncom gave themselves a large margin between what they advertized and what they were designing for (their chips work up to 450Mhz at the right voltage)

As far as the ETA on their chips, it's certainly something someone considering ordering now should consider. But at the same time I'm not really sure it's a good idea at this point unless they can specify when in October they'll actually ship, as well as how many units they're actually going to sell.  If it's late October and they're going to flood the market, might not be a good deal. Especially if HashFast ships, let alone cointerra.


You mean bitfury?   It's weird that we're not hearing more about them.  We probably should be. Oh well.
