Hi everyone,  im new here and new to bitcoins, I want to mine, I have a rpi and decent hub with 4a supply, so looking for some usb miner's,  anyone know who to contact for a couple?. I am in the uk.

yes no problem mate, send me your email address!  8)

cex.io is an option you may want to look at if you can get in at decent rates.  Right now i would be investing in the bitcoins themselves and not the hardware however.  Most group buys present risks and usually you are paying for someone else to profit so be careful with them.  Direct your own future.

He's probably a scammer who is increasing his post count by duplicating posts.

Participate in a group buy. USB miners won't ROI, and unless you have the thousands you need for your own miner, you best off share the exposure with others.

Group buys seem extremely risky to me, why not cloudmine instead where you can at least be in control of your own hashing?

I should mention that the ROI on both is crap, just asking.

The pricing is closer to at cost on group buys, whereas cloudhashing is very overpriced and require contracts. With bitcoin prices going up, many GB can ROI in USD. If you are looking for USB miners, check out http://minersource.net/

i got these usb miners if you need them!  8)

I'm not looking at all for USB miners, this isnt 2011.   I'm saying that a good amount of previous group buys have proved out to only benefit the individuals organizing the group buys and not the general share holders.  I think that individuals like you providing dis-information to the community is a very toxic thing to bitcoin growth as a whole.

At cex.io as an alternative example, the prices may be above current roi but at least your in control of your own portfolio,can sell hash as a trader and there are no contracts.  I see most group buys as one of the riskiest things you could do in bitcoin.  

Full disclosure:  I have no interests in cex.io, think their pricing is still far too high to invest in, I'm using them as an example here.  They are a risky choice but far better than what these shills would have you take part in.

Search bitmit.net, I've found some good deals on there for several different kinds of miners before.  At the very least, they currently list Block erupter USB's, Blue Fure USB's, Block erupter blades, BFL jalepeno's/little singles/singles, KNC saturn/jupiter, Bitfury 25+ GH kits and all sorts of other options.  Sometimes they are good deals, sometimes the sellers are smokin' the ganja on the prices they are expecting to get.

It's not mis-information, its just different personal experiences. You have a right to say some GB have not worked out, but I know a few people who have made a small ROI and are still hashing. You must agree that at this point you are better off hedging your bets on a GB rather than a USB miner. Be careful about accusing people of mis-information without supporting facts.

Your last post you were trying to sell this poor soul USB miners, now you say that i have to agree that USB miners are not worth the money......I think I was fairly accurate with my "accusation"

I never said he should buy USB miners, simply linked a website that sells them for, as far as I can tell, a decent price at $15. I never tried to sell anything, considering I have zero affiliation with the website.

I simply stated "If you are looking for USB miners, here is a website". Hardly selling.

at $15 they will never make ROI.....

Before you buy any miner I suggest you to study into Bitcoin difficulty first. Don't buy anything until you understand it fully..

Please post a site that sells it cheaper. I don't know one. If you do, do us all a favor and post it so that we can all use it. Never said it would ROI, simply that it was decent price compared to alternatives, such as eBay.

Do you understand how the difficulty works? If not you should dig into it. Otherwise you'll never make money mining.

Bitmit.net ... saw 50 of them sell the other day for $250  ($5 each if my maths are not failing me...), also have seen several on auction at sub 0.1 BTC prices as well.

Thanks for the good source! Might pick one up as a gift.

Also, didn't know about bitmit, thanks!

You are new to bitcoin, so you don't know what you want. Do not get into mining, the greedy guys with their ASICs destroyed it. There is no reason to mine, as you won't mine anything anyway.

What are the odds that he could solve a block with his USB miners? Thinking in terms of time, how long would it take to get a 25BTC block reward? (That's how that works, right? Newbie, here:-)

1 month, 1 year, 100 years, 1000, years?

As I understand it, it is a bit of luck too, right? A bit like gambling?

You'd want to pool it and get paid for your shares, or run it on an alt chain at much lower difficulty and buy back into BTC ... or likely both....  I'd personally recommend using multipool (us/eu servers available) for small hashers since the pool automatically helps you mine the most cost efficient coin of the day and all you have to do is decide to trade them or keep them and use them as you see fit.  Mid-sized miners would do well on bitparking, p2pool or eligius in merge mined configurations to get a slight profits increase and then the large miners probably imho best suited for ghash.io and btcguild  .... but that's just my opinion fwiw

but yes... like gambling but gambling in a way that is highly mathematically predictable.

It's funny that you say the price is "decent" because the buyer doesn't lose as much money as compared to alternatives. For a price to be "decent", I would expect the buyer to at least make a "decent" profit. I guess my standards are higher. I don't know why people insist on buying mining equipment that will never make a profit (unless, of course, they are doing it for fun or as a learning experience).

When you are in a pool it will allocate the easiest shares to the slowest miners. He doesn't have to solo mine. Meaning he will get payouts even if they are really really tiny.

Also, not everyone buys these little USB's for profit. I bought one for my younger cousin just to get him interested. Didn't care if it would ROI.

I would like a few usb erupters just to see.

I see they are cheap, but only in the u.s?, I live in the uk and they don't seem to be that cheap here :(

No, you might never accumulate minimum withdrawal BTC amount required by pools.

hey if you want hardware just make sure it arrives before the difficulty again rises and also it will be a retarget cheaper. The best way to mine now is cex. because the deploy the power right after the purchase. You can check my sig. Price is really good right now.

When I was mining on bitparking the 10TH/s pool took approx 24 hrs to find a block. Therefore I would guesstimate that one .333GH/s USB ASICminer would take an average of 84 years to find a block with solo mining but that is assuming no change in difficulty!

I want some eruptors as a hobby, not to make lots of money.

I am intersted in it, just here in the uk they cost equivalent of $50??!?

$5 each is nice for a test, but I suggest buying only few because if you have over 10 your HUB might get problems how to run them all.

I have one gigabyte 7970, its working 95% :) When try start computer there coming some blue lines to screen so i dont know what is problem. Sometimes go to windows and sometimes not.

hit me with your email! =)

I suggest only getting 1 to play around. It won't ROI :)

You mean after you start the mining program then it has blue lines?
