Is USB ASIC mining worth it?

[Capitalism Prevails]

Is the mining difficulty so high that these devices won't pay for themselves?

Of course not.  Do the math and youll see its pointless.

Where can get more info on USB ASIC miner?

Its not the current difficulty that counts. If it stayed the same you'd get your BTC back in 200 days.

But it won't stay the same, so how to you rate your crystal ball?

Have a play with http://coinish.com/calc (NB use expert mode to see the effect of increase in difficulty), and take a look at these threads https://bitcointalk.org/index.php?board=81.0

[KizunaAikawa]

they are pretty much novelty items at this point

[rumbitla]

For 1 BTC they would be nice.

[rn4j0r]

They basically are only good for helping get new people interested/familiar with bitcoin.

They cant mine anything really.

Check hashrate of the devices from wiki, calculate expected btc/month $/month, calculate power usage and get the profit.
Assume profit will be lowering each week a bit since increasing difficulty.

If you want you can take one unit and test it )

1.So if i want to spend a quite small amount of money on mining rig, what should I be interested in? I mean that the cost of the purchase should be around 2-3 graphics cards.
2. Is USB ASIC mining worth some cash when one mines alternate cryptocurrencies?

[chncoinsavior]

no

Can someone please add a link to these usb devices? I saw some discussion here some time ago but at that point theye were not selling them one unit at a time, one had to order something like a thousand units at least AFAI remembe...r

https://bitcointalk.org/index.php?topic=195004.msg2025318#msg2025318 but there are group buys (go up a level into custom hardware threads).

NowNOT worth it IMHO, but its your call. Do the math on the ROI.

[Edit] after all I've been bleating on about the last couple of days. I put in a typo that contradicts myself. Sigh. 
It might be worth it at 1.0 BTC, but not 2.0 BTC

[JaSK]

It's probably a convenient way of mining at work ^^

[treybird510]

Found it on this website, on here its 1.40 BTC (Don't know how you do that fancy shit with the sign and all)
http://www.asicgigahash.com/product/k1-nano/
But its one of them pre-order bullshits, don't know if its as long as lets say BFL or something.

Beware of scams. This is the official Klondike thread https://bitcointalk.org/index.php?topic=190731.0

As for that website, I'll get back to you once I've done some investigation ...
this is his announcement https://bitcointalk.org/index.php?topic=214125.0;all BEWARE it looks very SCAMMY to me.

Use the group buys on the custom hardware board https://bitcointalk.org/index.php?board=76.0 not some random website.
