Why everyone keeps selling their long waited ASICMINER USB?

[suryc]

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.

[razorfishsl]

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.....

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.

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 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?

[justmyname]

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.

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.

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.

The batteries are expensive because partly because of the expensive metals in them. A used battery can be sold and will be recycled, meaning that the environmental impact is fairly little.

The battery would just be for the USB/ASIC miners.
I was thinking more of tapped off a user's PC, not stand-alone.
Even w/o solar cells, the power savings over BFL/GPU rigs are enormous.

The power savings is not enough to justify the price, at least not unless you are off-grid.

Still - it's probably better to invest the money directly into bitcoins.

My guess is that the eruptors might become dirt-cheap in a couple of months. Then It might become interesting to have powered usb-strips with eruptors.

You're so full of shit, it's hilarious. The Jalapeno consumes about $0.07-$0.10/day to run, depending on local rates. If you believe that $0.07/day in operating cost is significant, you are almost CERTAINLY already living in your parents' basement...

how long is the wait from purchase to arrival ETA

[kevcoins]

is a hardware for the museum and for hobbyist to admire as a collector's item.. Asicminer is dumping his outdated hardware ... smart guy though

[echris1]

I have 6 of these now, and I look at it the same way as Xian01.  I have been running my 12 cards for 2 years now.  Some of my cards are just giving up.  I broke even a long time ago, and now I can upgrade to ASICs, keep running something, and use a tiny amount of electricity and air conditioning.

So I spend a few coins and stay involved, as my lovely rigs slowly burn themselves out.  =)

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.

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...

doesn't work that way. you could just buy 2.2BTC instead and have no energy costs and make 1100.
at this rate, a USB miner won't ROI, ever.

But where is the fun in that?

[seleme]

Because some of them bought it just to resell it to some other sucker and some realized they were suckers themselves by buying it at first place and now want to find some other sucker to hold the bag.

That's one way to do it.

Another is to replace existing gpus with these (aka sell gpus that already earned themselves out) use the profit from that to buy usb devices. Net effect - keep your hashrate - lose most of the electric cost. That's what I've done. Sure they're overpriced if I were using them to grow my farm but replacing gpus means these earn themselves out in a ~3 months based on power costs.

How is this possible, [assuming Jalapeno=>new BFL parallel ASIC]
if you hafta fan/refrigerate the crap out of em?

[marra]

blockerupter should cost 20eu max, I had one in hand yesterday, guy asked 2btc for it... we both agreed it's too much, with poor chance of ROI... and apparently, it gets really hot, passive cooling, you need a hub, can't plug it directly into comp...
