For ROI calculations, I ignore the exchange rate and use this simplified formula - It's not exact, but it's a quick way to do it:

Cost = 1.99 btc

Network Hash Rate = 78,000 Gh/s

My hash rate = .3 Gh/s

My Share of the Network = .3 / 78,000

Blocks found / day = 144

Block Reward = 25

Therefore, i will earn:

.3 / 78,000 * 144 * 25 = 0.013846154 BTC / day.

My ROI in days:

ROI (in days) = 1.99 / 0.013846154 = 144 days. about 4 3/4 months.

This doesn't consider an increase in network hash rate, which I estimate will cut profits in half every month until October. Considering difficulty increases the ROI is a little longer than 1 year.

This seems about right for retail cost, it seems a bit expensive at wholesale. Ideally, I'd like to see about a 1.5 btc wholesale cost.


If this key is not efficient enough ... what about all the GPUs that are a good proportion of the network ? ASIC is coming... but at what speed ? transition is not going to be quick. ASICMiner being the fastest, followed by DIY project for avalon chips. bfl ... is going to be soooo slow ...

there will be far more hashing powered added by asics than is taken from GPUs

keep in mind, mining litecoin / etc scrypt-coin, and simply trading them for BTC, has been consistantly more profitable than mining BTC for months now.  In fact i don't think it ever was NOT more profitable.

“Adding a LED which blinks when a share is found”

Is it a default set for the LED blinks?
Can I turn off the LED blinks?
Sometimes I don't like it blinks, but somethimes I like it so I can show it to my friends.

BTW, I will buy 10 if it prices at 1 Bitcoin.
As 2 Bitcoin, at most I can afford 1 USB.

Of course everyone wants them cheap, but these are the only ASIC devices available right now, and there is a limited number that can be produced. They are going to sell out @ BTC2 as fast as they can ship them. Nothing is free, this isn't a get rich quick scheme for customers.

Those who were hoping to pay $50 and make a massive profit instantly... I don't feel sorry for you. That's not how business works.

If you wanted to make 10x returns on your BTC, you should have taken the risk and invested in ASICMINER's IPO. You can't expect a successful company to give away products for far less than what people are willing to pay for them.

Actually I don't think any serious person was naive enough to assume they would make huge profits from a keychain miner, attraction was mainly for novelty purposes and as a stopgap during the delay in more capable ASIC being deployed to masses, since AM has proved credibility and can give short lead time.

I think a lot of people are NOT purchasing at this pricepoint- not because they won't make $$, but for the simple reason that they will not even recoup the cost of the investment, (from conservative predictions about the future increase in network power and diff) and this device has little to no resale value, and no alternate applications, it's just make no sense.

I imagine they would of sold like hotcakes at a lower price point, regardless there will be people willing to pay this inflated amount.. so smart to limit qty to bulk and have the retail take a mark up on end users, at least shareholders getting paid nicely, and they can pump this to the less savvy.

What's the historical failure rate of this company? If you get a DOA or early failure, it'll be tough to get support as they only deal with groups of 10 failures.

It appears to me that they would be capable of such a thing.

This isn't about high ROI guys.. that is a moving target anyway.

ROI seekers can build their own from ASIC chips. R&D and production still cost you know!!


Since I am running a ModMiner I would love to add these to my old p4 rig with it.

I'd buy 4 right now ~ can you ship?   Grin





It's not about "High ROI" It's about ANY ROI. PERIOD, or it's not worth buying. This thing will never break even at 2BTC.

I get that R&D costs something. The chip cost is about $11 (retail) meaning their cost is probably $5-$7, but we'll use retail costs. Consider another $15 for the board and components, and assembly. At .5 BTC, that leave them another $24/unit to cover their R&D/profit.

Now, I'm feeling pretty confident in saying that they'll sell at least 30* as many units at a more reasonable price point. If they're making 3000% the sales, at .142% of the profit margin, they'll make 428% more profit in the long run.

Not to mention that this price will remain more sustainable for a longer period of time, because the ROI will still be closer to break-even.

They're shooting themselves in the foot, trying to get rich quick. They'll sell a few of these for WAAAY too much money, on the short term. And then they won't sell any in the longer term. And eventually these chips become about as worthless as a 16MB USB flash drive...

Can these be used for scrypt --litecoins, feathercoins?

How many can I hook up to one motherboard using hubs? can I fit 20?

Thanks!

They can NOT be used for scrypt.

no. they cannot mine scrypt based coins.

gotta be powered hubs, obviously, but i don't see why 20 would be an issue. ...i think. i'm not a USB expert.

i don't post much, but this space for rent.

I guess I shouldn't be surprised if they actually sell these out. The world is FULL of idiots... Oh well. Your money...

Congratulations on your progress thus far, ASICMINER team!

This batch will be given away to miners, fans and hardware/software developers made the assignments to us long before. It has some issues working with cgminer, but the modular python miner works fine.
Speaking of which, did you donate one to TheSeven, author of MPBM?

Reserved for extension of contents.

The USB stick miner is going to bring BitCoin to the masses, beyond the geeks and hardcore or occasional miners.  This will make it mainstream.

Make this THE toy to buy for Christmas!!!

Congrats on making history!

these are not made for mining farms Smiley

I agree the wholesale cost is way too high, but I'm sure the initial batch will have no problems selling out.  I'm more interested to see what happens with follow-on sales.

Anyone know where I could find a cheap usb hub that will handle the increased (above spec.) power needs?
