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.
