Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC

[joeventura]

So, I'v been talking to a guy called "Jack Liao".

Claiming to have a 3MH scrypt unit running on these chips (i think) at 80w + 100ghs sha256 as a "bonus"

Anyone else been talking to him?

Hes from www.lightningasic.com

That's nice and all, but if he is selling it at $9000 its not really news.

Please let us know what you discover.

[Northlander]

Hes saying its ready to ship + its 2k$ ... Sounds like my own personal $ printer ....

$2k is doable, how would one go forth and order from this chap?

You pay 60$ a chip, they pay 1$.  They will push as many GH/sec as they can as fast as they can and mine themselves.  For them, these chips pay themselves back measured in hours.

If anyone is dumb enough to buy their chips, they will put out several dozen for every one you buy, funded entirely by you.

Scrypt is dead.

Scrypt on GPUs is only dead when the hashrate on network surpasses by a long shot the # and valuation of shitcoins generated, marketed and entering exchanges every single day.

I've been mining memorycoin which isn't scrypt for a few days though. In the best days, I got 3x the profit and the GPUs use ~60W each instead of 150

+1 i like your ideas
+2 for facts
+3 in a gold rush those who will sell parts will gain most capital. IF this company is legit and can do it, Scrypt mining. Only means there will be +10 more in next 6 months.

Scrypt for GPUs is not dead at this very date and for all gamers out there soon will be good stock of AMD GPUs that can handle all proper games nicely. Very cheap. All this fuzz and valuation of silly altcoins will keep up the GPU mining proftability for those people who want to invest time and focus on it. As power and watts per KH/s GPU mining is dead and ecological disaster. Dedicated chips will do the same Scrypt job with 1/40, then 1/100 and then 1/1000 of the Power cost of a GFX Card.

Also this chip will only currently do Litecoins. +6months there will be least dozen more companys with their chip solutions.

As a GPU miner which i am not. i would seriously evaluate ROI point and resale value to get ride of GPU mining and investing same capital to BTC or something else. Waiting for next wave of hardware mining. Early adopters always gain the benefits. The people who are planning to make 8, 12, 16 GPU rigs now... dont, you are too late. Goldrush is gone.

[Searing]

when is the next batch of these expected to be sold? and/or waiting list or whatever I may have to do to hear about such?

not sure i'll do so..but on the short list for the alpha scrpyt machine 5mh at 2200 bucks or so (I'm brave have 45 day protection paypal)

10 of these gridseed units look like a better deal and guicker out the door then july for the above alpha units  (again I'm fence sitting on all this just saying)

anyhoo a link to where to watch or get in line or whatever so I can keep track

their site simply says "coming soon"

Bad advice. GPU mining will allways be more fun and risk free than entering ASIC spiral that streams all the coins to ASIC sources. If scrypt coins developers want, they can make changes towards different algo. GPUs will adapt, what will happen to scryptASICS? They will continue diving into BTC ASIC spiral. That's why nobody is producing scrypt-only ASIC.

gridseed is just sold by ebay.
prices is fool.
but the pic with 5 chip is interesting.

Grid seed bitcoin litecoin miner 10pcs usb litecoin miner set
US $4,369.00
Power: 60W for one , 600W for 10pcs
rated speed :80G BTC + 3M LTC

So you get 10x 80GH/s SHA and 10x 3MH/s scrypt for $4,369.00 or how is this listing to be understood?

[ShadesOfMarble]

Thanks for the clarification. Yes, that's expensive.

I saw someplace else ...I think it was the first batch of 400 that is sold out..going for like 3300 usd or some such (not sure that ball park)...but can't find the page was a translated page someplace

so the guy on ebay is upping the $$$ by quite a bit if I'm correct in my rembering

no, you have 80ghs/sha more 3mhs/scrypt for 4,369 bucks..

this price is really crazy high

[Northlander]

The value of both btc and ltc must nearly triple if that 80g-/3mhs contraption will have any chance making the return of investment at the price of 4300 buckaroos...
Only reason you would buy this is if you're pretty darn sure that this will happen and hanging on to the mined coins until it eventually does.

[Cablez]

The listing says 10x.  Are we sure its only one unit?

Power: 60W for one , 600W for 10pcs

each device, i read here, make in double mode: 8Gh/sha and 300Kh/scrypt.
in the first post, there are specifications about hashpower of any chip.
any device has 5 cips (there is the pic about that)


10 devices costs 4,369.00 = 426.90$ each device.

[firejuan]

Fortunately the device is not that expensive. 1 USB unit with 5 chips is $133 and the controller is $66 so the total cost of a 20 piece system is ~$2700 (¥ 16398). http://mall.diginforce.com/goods.php?id=39

some Gridseed GC3355 USB miners have been sold out，they like this：http://www.cybtc.com/article-538-1.html

now the sell  only in china，one USB miner include 5 Gridseed GC3355 chips，about $133

BTC rate：10G/S
LTC rate：300K/S

power of  BTC+LTC Mode：60W
power of LTC Mode：7W

and many coinminers have 360K/S in LTC Mode

2700$ for 20 devices for 6Mhs in LTC mode only, is about 30% cheaper than equal hashrate GPU mining rig
but the great saving is power.

6Mhs gpu rig use about 2100w at the wall
6Mhs asic only L mode use about 140w + 100w? (my own valutation) for alimentation of various usb strips....

8.75 times less power!!!!

coinwarz: mhs 6000 power 2100 LTC net revenue 30.15$ (italian power cost applied)
coinwarz: mhs 6000 power 250 LTC net revenue 39.11$ (italian power cost applied)
it's 29.72% more profitable

definitely we got 30% more profit whit 30% less investiment.

so i'm sad... i just ordered my 5 gpu...

Don't be sad, gpu's have great resale-value - both miners and gamers are still in love with those nifty little chips from amd.
But I think the price is about right for that scrypt-asic miner and if they are able to provide the scene with a steady supply we'll see an even more rapid increase in difficulty and thus rendering our nice little gpu-rigs utter useless for scrypt-mining soon. Sigh.
Unless you've got some crazy deal with free power and cheap gpu's (got free power myself tho. )

[poppys]

So total per month for each one in $/kWh is

$350.00-USD 1x 280x 720kh/sec 0.09$/kWh 24/7 x 30 days = $16.20-USD
$1200.00-USD 12x usb miners 720kh/sec 0.09$/kWh 24/7 x 30 days = $1.50-USD

You would save $14.70 per month on your electricity bill, however you spent 650.00 more for the USB miners. It would take you 44+ months to make up for the cost.
So is it worth it? Not with AMD pumping out 20mn chips soon.

Also quick resell value of the 280x, around 300.  USB chips that only do two things? Not worried about ASIC for scrypt at all.
