Gridseed GC3355 -Hybrid Scrypt/SHA256 ASIC

[regmann]

Guy could someone work out an average ROI on one of these sets. $2700 for 3000 hash power. It seems to work out 120-240 days before roi is reached. Or am I missing something? with more and more of these units being sold( a huge amount) isn't this also going to up the difficulty in the coming months? does this mean that coin wars calculator for coin profit isn't accurate because it doesn't take into account difficulty increases in coins?

If hypothetically you were to mine 3000/ms on middle coin for 4 months, would you even see roo in 4 months? Also these units are new so if they fail after 2-3 months(which no one knows it true or not, isn't this a null void waste. I understand there is risk, but it seems a bit troubling to say the least when you do the math from say March onwards..?

insta mine new coins
price of coins u mine gowing up
total power cost
vs gpu cards <

all in all if u play it smart could roi in about 1 week ( or 2 months )

you mean its not an instant money machine? well forget it im out then.

I dont mind waiting, I was talking about the miner lasting longer than 3-4 months

I make about .025 on middlecoin each day with 3mh. So you are looking at about 6 months to ROI.

imho too risky to wait 6 months when these puppies could break down anytime... i'd bite the bullet if warranty was more solid and not just 1 month...  i still make money with my gpus after subtracting power costs not to mention i can always sell them off, have them RMAeds since most of them are backed by 2-3yrs warranty... also one thing to note scrypt's initial goal was to prevent centralized mining by asics and it's possible as soon as scrypt asics flood the market it won't become any different than sha256 and new coins are going to drop scrypt in favor of more sophisticated algos that would motivate more distributed and decentralized mining...

So you think when these more sophisticated algos pop up... GPUs will be able to switch over more easily before asics catch up? I still think GPUs are the best option for scrypt (price/kh, re sale value, etc), but even better if they can hop over to a new algo in the near future.

If anyone is interested to get ROI on these.

I have them for sale at www.zoomhash.com

Check out my feedback on ebay and amazon .

who can send me to europe ? please PM.

I  got my scrypt asic miner gridseed from http://hash-master.com/ they have good prices  go check them out.

you price is not competitive at all

[vabchgent]

So far on these the best price I have seen on the gridseed is Zoomhash.com at least in the us. I have ordered one to see how they work  and test them out. Theres a site in China and I believe it is the distributer selling them for 150 USD but you have to order a large amount 50+ I think was the number.

[forzendiablo]

where can i order those in EU ?

Anyone setup a LA3M system using the Version B Control Board (the red one)?  I think mine was dead on arrival but in case for some reason I just don't understand plugging things in I wanted to see if I wasn't the only one with a dead unit.  Plug in on the separate 5V connector, Ethernet, MicroSD in, etc. no lights or any signs of coming online.  I don't know what they would use for the JTAG connector so I cannot bring it up with my Xilinx USB Adapter to see if it can boot that way.

[lmazzola]

I have Gridseed miners in my possession let me know if anyone is interested. My partner lives in China by the factory. I have been importing and exporting for 14 years now.  I am located in the Ann Arbor Michigan area we have daily flights to and from China for all products.

According to this review, the 5-chip Gridseed Miner pulls almost 60W mining Litecoin and only does around 350KH/s...

Is there something I am missing?  Why are people spending $300 on this ASIC, when a ($110-150) Radeon 7850 has equivalent specs and about the same hashrate (ie 350-380 KH/s)??

325 kh/s at 10W is way better to host for heat and power than 250Kh/s @ 10-20x the power and heat.
