Bitcoin Forum

Hey guys, Im new in bitcoin mining, I bought usb antminer u1, I am thinking about buying like 5 more or so. For that I need usb port erupter, can someone show me where I can buy that in UK,give me a link or so and which psu I need to buy.Thanks.
By the way, Im thinking to buy antminer s1, is it worth to buy this miner for a newcomer into bitcoin mining?
Thanks guys!

I can't suggest you a usb hub, but antminer u1 or any asic-usb won't ROI. I mean it might will in 5 years. Antminer s1 is no longer available, but I own 6 of them and love it. Bitmain has released their latest S3, and I would recommend to buy those instead of using U1. Much faster and ROI will be less that a year.

Hey only bump your thread after 24 hours.

The reply you were given is largely right. Don't mine on usb.

I guess you won't listen, so http://www.amazon.co.uk/TeckNet%C2%AE-Power-Adapter-Cable-Chipset/dp/B00DCO9YVM/ref=sr_1_20?ie=UTF8&qid=1405196453&sr=8-20&keywords=bitcoin+miner

This is what you need. May not be the cheapest out there. Also, I and half the members here will have 2 or 3 of these knocking about nowadays unused. Maybe post a WTB thread.

S1 isn't worth it anymore. S3 is marginal.

Oh,ok, thx for the info. I bought s1,is it that bad? It will be my first try. Can I contact you via pm if I face any problem or want to make a better decision?

well now that you ordered an s-1

a)  do you have a psu for it?
b)  do you have a ethernet connection for it?

I can suggest ways to mine with it. 

1 day a week you could solo mine it on www.bitsolo.net if you win you get 25 btc odds are you won't

6 days a week you can mine it at www.btcguild.com it will earn  steady fraction of coins but not a lot of them.

That's more good advice. pm if you must, but idk anything about mining problems except how to search for helpful threads

Basically whatever hub you use, it has to be powered: 5V 1W must be available for each miner.

Any more opinions?

Find a powered USB hub. You shouldn't expect to ROI anytime soon. The difficulty is increasing too fast and it consumes too much electricity and the price per gh ratio isn't good.

Firstly, I would like to ask what is "ROI"? What happens when the difficulty is increasing?

ROI is revenue of investment. Which means that you earning what you invested. If you invested a lot but the returns is low, you probably wouldn't ROI. Difficulty increase means that you need more shares to solve a block. When more shares are taken to solve a block, your payouts will be lower per share, and it would be harder to share.

So you mean it's not worth anymore to mine bitcoins?

It depends on a lot of factor. The price of btc to fiat, predicted difficulty increase, electrical cost and hardware cost. You can still make a profit if you can get cheap and efficient hardware and low electrical cost. There is no guarantees if the difficulty would increase very fast or the hardware would have a short lifespan. It is a gamble to make a profit of mining.

Could someone help me? http://www.part.lt/perziura/a82178e01e5b2b748880b131ede54ea9372.png open this screenshot,how to create a wallet address?

How about using online wallet? I probably not the most secure thing on the planet, but it gives you flexible to access your wallet. Back up is pretty important too. I format my computer without back up the wallet, and all my money is gone. That's not gonna happen with online wallet. Blockchain.info, I recommend this one. I use it myself, and it's been a pretty good one.

Cheers  :)

Thank you, I was waiting like 20 hours to load that wallet,oh ok...

I rather buy a direct 1Ths machine but darn heavy!

Can always get one hosted.   But USB miners as mentioned are not really for anything but fun.  Can get a lot more power for your dollar by buying a true miner.

What do you call a real miner? Show me the best option( Im talking about the price/power)
