Why everyone keeps selling their long waited ASICMINER USB?

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...

Yes it gets too hot to touch, but it will run fine like that. You can plug it directly in to a computer, i ran 6 like that for over a week. Hubs just make it easier to run larger numbers of them and the fans just make people feel better running them cooler, not needed.

I'm not sure why people bought them up in the first place, they cost the same as a half decent graphics card, they hash about as much, but have no real resell value, it's only the fact that they're USB and lower power consumption that they're worth while, for me they're worth nothing as I mine electricity cost free, I liked the idea of being able to just put loads attached to one machine though.

people keep saying there is no resale value.. all I know is they can be bought from source for around 200 USD and sold for a little under twice that on ebay. I might be wrong but that looks like an 80% profit derived from resale benefits.

Currently people are paying < $300 on eBay. the demand is dropping quickly.

Right, because the product is not worth 2BTC and folks that can do basic math realize this. Fair value for a 300 MHs bitcoin miner at the moment is probably ~$50.

if, in a years time from now 1 BTC = $500 dollars then these little usb gizmos will have been a steel...

but BTC could be $50 too!

These are selling on eBay now for around $280 - $300, down from ~$400 a couple weeks ago.  Some are not even selling, either.

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?

Looked at from a purely financial aspect, these are not a good purchase unless the USD price per unit stays the same but the BTC --> USD value increases or the BTC price of the unit drops.
