Last time I checked, one USB block erupter was around 1 BTC.  As of 9/24/13, the price is now 0.3 BTC!!!

Sorry for posting in newbies section, but I can't post anywhere else...

You can get them for like .15-7 now I think.

I never thought I'd live to see them drop below 0.75 BTC

It is kinda over priced.

you can buy them from me for 0.13!!! see my signature, i have a listing on bitmit for slightly more due to the whole escrow thing, but stil cheaper than the one you listed

did they deliver?

Still, is it even worth it?

how many MB is it running ?

if you're looking for a return on your investment, i think a $5 price point would be marginal (decreasing daily)...  i guess some of it depends on your electricity costs (how much does it use anyway?  around 3-5 watts?)...   if you just bought one,  a lot would depend on your computer habits too, i suppose (i.e. do you leave it running overnight etc)

anyway, if I saw one for a few bucks, I'd probably grab it...  maybe as a potential collectible, wtf... replace my star wars collection

Better to purchase the Butterfly Labs 5 GH/s box.  Lowers the break even point.

Yeah, well, ROI is crap.....

On the topic, if I found one cheap, I have no idea how to mine, or set this up at all.  It looks greek to me.

Can I run it on an old computer, that is just sitting there?  And would someone walk me through it (in english, not all these crazy tech wording?)

Use Bitminter, makes the process plug-and-play.

I'll sell you one for 0.12 BTC + shipping and walk you through setting it up.

I see people using these hubs and stuff, for multiple ones.  How hard is it if I bought like 9 of them, and hooked them up to run 24/7?  Will it work on an old computer?  And how much startup costs?  I have the computer, thats all.

You'll need a fan if you have that many.  And you have to get a hub with enough power for them, like an Anker hub.  You should just start with one and see if you like it.

I may PM you in the next few days, to discuss this more, and maybe buy one or two.

Main problem is power to the USB hub.  Seems like expensive hubs just have higher amp power supplies when compared to the cheap stuff. 

Setup is very simple: install the drivers, plug in USB hub, plug in erupters, d/l cgminer or bfgminer, make shortcut, edit shotcut to include proper parameters, run.

The whole issue is whether it's worth it to you, when ROI (at chrrent difficulty and costs) is about 3 months.  Realistically, I'd be surprised if my ROI is 6months.  This is mostly a fun project for me, since electricity costs for me are $0 (running solar that's making a surplus).

Oh, and it would make a neat warm plate as well.

IMO, block erupters are overpriced even at 0.175 BTC (http://www.asicminer-shop.de/)

Drop to 0.1 and we're talking again.

Friedcat is selling them for as low as 0.1 BTC.

0.1BTC sounds good to me! I've searched Friedcat's posts, but can't seem to find anything pointing to a place where I can order them. Anyone have a link, or is it all done via group buy on the forum?

you can get them for $18.99 on amazon, or slightly less if you look around.

Still overpriced!

If you had 9 of them running 24/7, you'd mine about 0.09 BTC a day (from what people elsewhere are telling me)

That means I'd hit positive roi in like a week....

Starting now, 0.49 BTC return: http://mining.thegenesisblock.com/a/0f6d51ab6e

So, each should be under 0.05 BTC...

Or 0.01 :)

That would be nice. :)

I have 9 running right now and as of last night they bring in about .014 a day for all 9.
Not sure where you get the .01 a piece, more like .003 each.

As difficulty goes up, your return goes down.
Current difficulty is 148,819,200, and 3 months before it was 12,153,412
(https://spreadsheets.google.com/pub?hl=en&hl=en&key=0AmcTCtjBoRWUdHVRMHpqWUJValI1RlZiaEtCT1RrQmc)

So, your daily return could have been 10 times more 3 months ago.
From another viewpoint, in 3 months, your daily return "could" go down to just 10% of your current one (if difficulty keeps going up at this pace).

totally changed my mind, I wont be buying these :(

That's why the price of erupter crashes from 1+ to 0.1 BTC now.

Can you sell it to me?
If so PM me

I guess I'll say  that I do really have *some* interest

I don't suppose it's possible to get a price of $5/ea or less even when buying several hundred units?
