All of this is true, but these people are helping secure the bitcoin network by adding to the network hashrate. We should be encouraging this kind of behavior Wink

This is a common fallacy in bitcoin propaganda. There is no secure bonus with higher hashrates. The network keeps secure by an adequate balance of difficulty and hashrate. And this balance is guaranteed by the algorithm, not the miners.

Disagree. 51% becomes more and more difficult the more hashrate + higher distribution.

I agree with higher distribution.

But not with higher hashrates. In fact, now we are in much more higher risks of 51% attack due to the almost centralised production of ASICs. If some ASIC maker would take over bitcoin the cards are on her hand.

OMG .Fools and their money! When this was announced difficultly was under 10m and network hashrate under 80t/h. Now you've got them it's 12m (+20%) and network hashrate is 100t/h+ . In under 3 days difficulty will hit 14.4m. So thats a 44% increase in diffuclty in 5 weeks, around the 30% + a month I predicted.

Disagree. 51% becomes more and more difficult the more hashrate + higher distribution. The safety factor is in high hash rate + high rate of decentralization. So when an individual plugs in 300 MH/s, they are raising the hashrate and decentralizing the network a little. This is not a common fallacy, it's common knowledge.

I think it's a big novelty factor - these things are selling on Ebay for $400 at the moment.

This is precisely why I bought ten of these things. It's REALLY easy to make ROI if you end up with 4 units at zero cost

This has the worst Mhash/$ ratio of any asic device out there at 1.22Mh/s per $1. The runner up is asicminer's erupter blade at 1.87Mh/s per $1.

How do they get away with it? Because it's basically the only form of asic being shipped without a pre-order...

yup. i give them full credit for finding a price people ill pay and selling at that price like they are. I wont invest for another month till we see some competition push things past 2Mh/s per $ on a small scale or 4Mh/s per $ on a larger scale. There will be intersecting curves of supply, demand, and technology that will see an 'ideal' moment for quick ROI and lasting profits past 2 years of use (the block erupter USB will take 7-14mos to ROI, and would be incredibly lucky if it ever made a 100% gain in the 2 years following).

im thinking this nice little point in time is about a month or 2 away, and will consist of avalon chips being made into avalon knockoffs and the k1/k16/k64 style boards, plus a newer version from asicminer that is faster and better priced to the market.

If i cannot make my money back with a unit in 6 months from the day i receive it (not place an order or first see it on sale), then the design doesn't interest me. If a system returns its cost in 6 months, you could see another 100% profit after about another 10-18 months, and after that (2years) the device will make little more then the electricity it costs and may even have burnt out or failed already.

Yep, 40-45°C for 3 months here in central Australia will do that

Uh, NOT.

What kind of cooling should I aim for with 50 of these bad boys? Keep in mind my #1 concern is noise level. It may be very close to a child's room and I don't want it to be noisy. The house does not have A/C. Although I live in Canada, our 2-3 months of summer can still be scorching hot. Cool

someone should tell them before they ramp up production Wink

...or maybe... they'd just slap BTC COMPATIBLE on the box!

What is the range of hw errors as a percent of accepted shares that you're getting, please?

On my working one it is running at about 0.9%. (IIRC, several other folks have reported getting about a 1% hw error rate.)

One which is now dead and in the process of getting replaced ran at about 10% hw errors for roughly eight hours. Then it died.

-- edit

NOTE: I had a fan blowing over them. They were both 'warm to the touch'. Not the 'freaking hot' you encounter without active cooling.

I'm getting about 1.1% HW errors across my 7.

Great to hear that you've got the rest running now! Did you end up running the rest on a second machine (mac)?
