I see that most of the USB miners have (at current difficult level) about 6 month return period to start earning. That makes them not profitable at all. Are there any profitable usb miners?

No.

If you have them in hand there is more profit to be made selling them on ebay

Good thing this hasn't been asked at least once a day for the past year...  (TRY LOOKING BELOW)

Just as I expected, thanks

Should just remove the word "USB" from the title and lock+sticky the topic, no miners being sold are profitable right now.  Next three months is looming on doomsday for the gen1 devices from every manufacturer.

There is no certainty what tomorrow brings. A lot of people will assert themselves as having clear vision of what the future brings... but they don't. No one does, obviously, besides the 'man upstairs'.

However, IMO KNC Neptune is your highest probability bet right now. The shitty thing is that ordering one today puts you at the end of the line, at the outside time frame of when your rig may become profitable. Even if it's still not a great bet, I think it's the best bet you can make right now.

Once 2014 Q2 rolls around (which seems like eternity right now, for those of us waiting on hardware :| ) the network hash rate will explode as all of our machines come online. It's what happens between now and then which will set the stage for us.

Scenario A - "Bad times" case, otherwise known as losing your(my) shirt

difficulty is above 20 billion
value has contracted below a few hundred
used hardware sales dwindle

One variable which will only increase these estimations is the hash rate the KNCminer will pull. 3th minimum, hopefully 4.5th or more.

Scenario B - "could be better could be worse" case, possible +ROI, extended time frame

difficulty10-20B range
Value Stays between 750 and 1250
used hardware sells as it does now for 2x+ retail to Ebay d0nks



Scenario C - "I'm rich, beeyotch!" case, +ROI, get'n it while the get'n is good, then selling the kncmienr while price is hot

Difficulty stays below 10b
Value gains pick up speed, and goes between 2 and 10k +
ebay d0nks replicate, causing high demand, prices skyrocket - Cha ching!

From my experience, the ASICMiner Block Erupter 333MH/s makes me 0.01BTC every 1½ month at least. I made 0.03BTC before stop mining :P just for fun.

These BE values around £70~ from ebay sellers (ebay is crazy).

If you are looking to get some BTC, I suggest you to 'rent' your signature space.

I have some IceFury Miners for sale up on e-bay right now. Currently it is one of the best for the price vs hash and power consumption. However, who knows what the future will bring in the realm of ROI? :-P

Specs:

Batch : Ice Fury
Power Source : USB (@ ~2.5 watts)

If you're interested, you can either make the sale on e-bay and pay with paypal in USD if that feels the most comfortable since I don't have a more seasoned account on here, or hit me up on e-mail (boldar at gmail) and you can pay with crypto. (BTC or LTC preferred but we can negotiate)

I'm having the same experience with my BE, last month maybe .01 BTC.  I'm going to try the Antminer U1.  Expecting .01 BTC per week?

I just unloaded my 13 BFL on ebay and bought a chili rig. Just within the last couple of days, I've gone from .0019 to .0013 a block running at 35 gh/s. It's all about custom rigs that can turn out 100's of GH/s plus. No reason to buy the little stuff.

Also, remember this:
USB stands for yoU Suck Balls. Don't buy a USB miners.

Chili rig?   Audio equipment.

I almost bought a USB miner .. thank you for the information..
