You could buy four 5 GHZ units from Butterfly for the same cost. Then you'd have 20 GHZ if you ever received them.

Except you can't buy anything from Butterfly at the moment and the Erupters are in hand. When you can get 5 day Delivery from Butterfly, Erupter's price will adjust accordingly.

I assume there's a way to bring power off a 12-25v solar cell pack
[ like the ones JC Whitney sells to charge car batteries ]
or a less-overkill cell
and down-regulate it to 5VDC for a USB hub?

Google "buck converter" (sounds like some shady finance shop. but its a PSU). Though I don't understand the hype about solar powered mining, any significant downtime (like overnight) hits your ROI hard. Maybe its more environmentally friendly (but not with all those batteries you're going to need to run 24x7), but it hits your pocket.

Their kind of neat but you would have to have 15 of them to equal just one 5 GHZ Butterfly Lab unit. Maybe you could buy them for way less than $250 direct from China. Otherwise, I would even feel better about ordering from (gulp) Butterfly Labs. You could buy four 5 GHZ units from Butter fly for the same cost. Then you'd have 20 GHZ if you ever received them.

the fact that they're USB and lower power consumption that they're worth while

With a lot of folks still on the grid, this is important.

I like the idea of half life. You guesstimate how long it will take the difficulty to double, work out how much BTC you will earn in that time. That's your half life, you've earned half your lifetime earnings. You will only ever earn twice that much. Basic exponential math.

Of course nothing grows exponentially for ever, but you'll probably be bust well before then.

Bought, tested and saw, that they don't make the money they have expected - now selling?
I mean, everybody has some USB ports available and 333MHz should return the investment quick esp with that powerconsumption. Why selling instead of mining?

Currently If you do not see a return on a rig in <70 days.... you are STUFFED.......
~+10% change every 10 days means each period you mine with significantly less efficiency than the 10%

I.E
difficulty
100 +10% =110 +10%=121+10%=133.1

So it is already >33% LOSS of efficiency from base after 30 days.

These things are looking at OVER 1 year if the CURRENT difficulty does not change during that period.
Then you have the idiots on ebay buying them for $500 bucks because they think they will get rich......

In november last year you could easily mine a couple of bitcoins with 200MH/s, now you can only mine dust.....

Play2Live pre-sale starts on January 25th

Because at current difficult it would take about 8months for one of these to generate the ~2BTC that it costs. And, difficulty is about to skyrocket.

I think these are mostly a novelty item at this point.

Because they are to expensive to give any profit?

Some are trying to get a quick profit from reselling.

Think of it this way: if your goal were to profit based on the assumption that the value of BTC will rise, then your best move is to buy one of these at 2.2 BTC (around $245 USD currently) and then sell it on Ebay for around $400 USD. Take that $400 USD and buy BTC. Repeat.

That works even if BTC falls in value (a bit anyway). Doesn't seem very ethical (taking candy from babies), but that's what Avalon/BFL/ASICMINER are doing to their customers (well the new ones anyway).

Assuming the price of bitcoin will remain the same... - if, in a years time from now 1 BTC = $500 dollars then these little usb gizmos will have been a steel...

Not if you bought them with BTC though. And if you bought them with dollars, your would have made more profit by just buying BTC on an exchange and leaving it in your wallet.

Then buy 2.2 BTC with USD. You get the same benefits of BTC exchange rate rising without losing 2.2 BTC on the assumption that the value will rise.

Plug in 333 Mh/s for $250 into any of the calculators that take into account an exponential rise in difficulty and you will find that these never break even. If the difficulty is rising exponentially, which there are strong indications that it is, these items will make less and less at a rate that means they never pay for themselves at any power use or electricity cost.

I plan on running some and selling some on Ebay. Profits from Ebay means I won't need to cover the cost of the ones that I do run.

Also, this is a way for people to convert their Bitcoins into fiat money without going through an exchange at very favorable rates.

Don't think about the next 120 days. Try to think about the next two years.

We don't know what the reliability of these will be. My two GPU's have been mining 24/7 for over two years straight.

Will these devices be able to do that? I hope so since I bought some too. And no they aren't for sale, yet.

Probably because people are not thinking long-term.

I've been mining for 2 years now that has allowed me to amass enough BTC to upgrade to current ASIC hardware with $0 fiat out-of-pocket.

I hope to be mining and growing my farm over the next two years at least.

Granted, if BTC/USD value tanks, we're all taking it in the pooper Sad

Point is, yes the USB miners are costly, but they are way more energy efficient than GPU's and will ROI faster... in theory.

Don't think about the next 120 days. Try to think about the next two years.

I bought one for the following reason:

-They are cool looking
-They are not a "preorder" with infinite waiting time
-They are very small
-They are within my price range
-They have very small power consumption
-I live in a small apartment in Texas (3 video cards = enough heat for half the apartment in the winter. Now that it is June, running 3 cards makes my A/C run all day every day)
