Hi, i never tried mining, so i was wondering should i buy 40 erupters and start mining with them?

I have 3 more questions..

1. when you think i will be able to get 23 btc back?
2. I have 2 laptops only (1st is normal laptop second one is a mini laptop), I don't have any desktop.
so do you think they will be able to handle 2 usb hubs on each of them?
3. do you think running a laptop 24x7 is a bad idea?

It will take at least 4-5 months at current difficulty, which is irrelevant as difficulty will not remain the same. I'd say something north of that if ever for ROI. Dustcoin.com is a decent place to start.

I don't see any inherent reason the laptops should have issues from running 24/7. If you were hashing on them, however, they may overheat. But since the hashing is occurring on the USB sticks, it shouldn't be relevant. I'm not positive about the hubs, but I don't see why not.

Thanks for reply, i already checked dustcoin,according to it, i should get 6.52 BTC  in a month  (333x40=13320 MH/s) but as you said it depends on difficulty level.

So do you think i will get able to get  (6x4) 24 BTC back in 4 months ?

That calc is pretty much correct. Also, you can mine SHA-256 Alt coins on them.

Another thing you can do to save much more electricity is to buy one Dlink 7 Port hub which supports only USB 2.0 and use Raspberry pi to run these erupters. This will not require laptops and you will save on the electricity as well.

P.S : Am doing a USB Erupters sales in the marketplace if you are interested https://bitcointalk.org/index.php?topic=263692.0
The prices are at par with the market and lesser to some other group buys.

Let me know if you want to buy in bulk. Probably i can throw some freebie for you(probably a Raspberry pi for you. Not sure. depends on the order qty).
Thanks,

Thanks for info guys, any suggestion about pool etc?

Ps: Thanks for your offer americandesi, but i prefer to buy directly.

btcguild good pool, you can join Team India there, currently on 17 place.

http://ozco.in/  good too as reserve secondary pool, they have server in AUS with good ping from India and low load. Read about payment methods, it is quite important, how much coins you make may depend on which payment method you choose.

alt coins now not much use for ASIC, terracoins been brutally forked few days ago and nearly  dead now.

I've operated 61 USB erupters, and the most important thing is to make sure your hubs can handle the power load.  4A@12V 10 port Ankers are good, and so are 5A@12V 10 port hubs by "Juiced Systems".  Each erupter requires 510ma@5V or 2.55 Watts of power.  The hub itself will use a couple watts.  You'll also want a bit of airflow or things will get warm.

As for pool, I personally prefer p2pool.  I get to set the rules for the blocks I attempt, merged mining is easy to set up, there are two channels to propagate solved blocks on (resulting in fewer orphans), and there is no fee unless you donate to the author.  It does take a bit of systems administration knowledge to set it up, although you can also mine on a public node.  However, many public nodes charge a fee.
