Topic: [First Avail. Reserv.] CT/HF Bare Rig GB + Bitmine 28nm Chip Buy discussion (Read 11602 times)

Well, that's just my opinion. We all need to do our Due Diligence and come to our own conclusions.  

FWIW, from discussions with various members there already appears to be a commitment to a good chunk - over a quarter - of a potential $50K chip buy from Bitmine.

Please PM me if you might be interested in this. You wouldn't be held to any commitments, at this point: it's more of a gauge of market demand that could help tip the balance as to whether this particular Bitmine Coincraft 28nm ASIC Chip GB/potential rig assembly project goes forward or not. Of course, if there's enough demand and enough members & cooperatives band together, a larger chip purchase yields a better value for everyone involved.

Thats great for putting my mind at rest a little.    might be a viable option!! 

This was from a PM I sent after a member asked me my opinion on Bitmine. Since Cointerra & HashFast haven't been forthcoming so far about chip purchases and platform support, just thought I'd share my findings on what's looking to be a viable option for a 2013 ASIC 28nm Chip Buy:

"Bitmine passes the sniff test for sure esp. when you compare them to those new scammers GMHS which appears to have been registered in Russia but is trying to pass itself off as a Hong Kong mfg..

I was dubious about this Swiss team only working on their 28nm chip for 6 months but Giorgio was upfront about it when I questioned him. When I went to their site I was impressed with the openness I saw with LinkedIn links that were real & had actual pro contacts in their industry, as expected. Their reliance on Innosilicon and Global Foundries is a great thing IMO; get help from experts where you need help, do what you can on your own. As long as they get to tapeout without stumbling at the finish line I think they'll be able to meet delivery by year's end..."

Well I asked them about buying bare chips with or without pcbs and the answer is that they dont have any details about that (even icedrill bought them)

They also told me to stay tunned to the website because they hope to have an announcement soon. Nice in that aspect for HF 

That's the joke. 

Well, they are calling their machines Mercury, Jupiter, and Saturn.

Actually its only $100 per a chip, $50000 for 500 chips. That makes it $5 per a gh/s at 20gh/s and $2.50 per a gh/s at 40gh/s. Pretty inexpensive really. A bitfury chip is $25 per 2.7gh/s which makes it $9.26 per a gh/s, significantly more expensive than these chips. These chips and the bitfury designs also use similar amounts of power per a gh/s, with a slight edge to the coincraft asic.

It's a shame that Hashfast isn't offering chips, these chips could be good. Hashfast's small batch sizes are probably actually good for bitcoin mining as a whole, however. By keeping down the hashrate they flood the market with, they keep their devices more profitable.

 It may be a terrible thought, but personally I hope that any asics I do not purchase are slow to market or vaporware. It is shaping up to be quite a bumping ride in the overall hashrate with VMC, coincraft, and avalon v.2 being announced, not to mention KnC appears to be shipping in astronomical quantity. BFL has possibly sold 3PH/s of asics, who knows if they will even deliver this.  The quick reselling of another batch of KnC could very well flood the market beyond profit for even their customers. For every asic they sell, they devalue the other asics they have already sold. I was slightly worried before, but now I really feel we may have an astronomical hashrate by January. I would even go so far as to claim a lack of intelligence in the planning of asic designers, as this flooding of hash power does not seem like it will end well. While it makes me sad to say this, I really hope a few of these manufacturers fail to bring chips to market.

I welcome anyone who can actually ship product! 

That said, am I getting my math wrong or is the $500 per chip, capable of 20GH/s to 40GH/s, a might bit more expansive than the BitFurys at 2GH/s for $25?  If BitFury was double cost, it could be equivalent to these and you already have an IC for them?   Yes, you could order a larger quantity and get it down to $4.50/GH/s but that still leaves alot of room for the BitFury's to cost more and still be cost effective. 

 I don't remember the the GH/W of the BitFury's though, and that's the dominating cost if you mine for awhile.  I think the BitFury's were around 2W/chip?  Which would make them 1W/GH right?  These claim somewhere between 0.6 W/GH to 1 W/GH (unless you undervolt them).  So I guess these would win out should you keep them mining for long enough.

Looks good, but of course I will need to do a little more research as i`ve not een a great deal on these

As far as i know they aren't. I have written to them asking and they haven't responded yet. Would be nice though.

Hey guys. Yes we're still working away at getting something good happening for the next project. VMC and COINTERRA are still on the table but now also very interested in these:

Thoughts?

Barntech

So does Hashfast have any plans for selling bare chips? I haven't seen anywhere where that was their intention, other than for the protection plans. I'd love to see them throw bare chips on the market at a nice price. I certainly like variation on the market as far as chip designs.

Got another PM reservation for one or more HashFast bare rigs. Whoever organizes the first HF Bare Rig GB is already going to have a pool of customers with reservations right here.  

The news gets even better! ...at least if you're a B1 customer.

"everyone, please pay attention:

"The Baby Jet motherboard has room for an additional GN chip.**"

this applies to the Batch 1 units as well." - cypherdoc https://bitcointalksearch.org/topic/m.3117974

Looks like all those B1 units can do 800-1000GH/s once you get that second chip.

Guys, I just talked to Barntech. He says it's too early to make reservations for his next project. Sorry, if there was confusion. Don't worry though, he's hard at work on his next project.

However, this is *still* the place to make reservations for your a bare rig for Cointerra or Hashfast bare rigs.

As for Avalon or BFL, I refuse to deal with manufacturers that disdainfully treat their customers the way they do.

Did anyone see this today? http://us5.campaign-archive2.com/?u=238a9ecd2e5192e3cd3ace26d&id=1a696dd59b It looks like avalon is designing a second gen asic. I can't say I would trust them at this point, they seem like real scumbags or they were just in over their heads. Maybe they can turn it around, and I do like how the design specs will be published ahead of time. The fact that preorders won't be taken or required makes me think this may go better. I'd have much less reservation about purchasing chips ready to ship than preordering with bitsyncom.

  AS I SAID I have 4 group buys cooking and if just one starts as promised I am in for 5 coins give or take a coin.

Yes, the idea for the design for the VMC chips would be simple, basically the Drillbit System pimped out for the new chips. Standalone boards that can be stacked if desired. The Cointerra thing would be pretty different, single chip boards that would require serious cooling, most likely not stackable, though at that size, you wouldn't really need to.

Nice to see that there is some decent interest in this. More soon.

I am also interested in investing, not sure how much I can afford to lose (invest) yet...

Very new to the forums, still getting my head around most of it.

I'd be interested at the 500-600USD price point.

I'm interested in the hashfast bare rigs, it's nice to see Barntech is involved. With recent difficulty increases it's looking like baby jet customers will be getting extra chips.
