Hi,
I am looking to start mining possibly and it seems pretty cool. If i were to buy 100 dollars of block erupters or however the most efficient way of doing it with a hundred dollars, how long would it take to get 1 bitcoin? this $100 does not include a computer to run the stuff on like a raspberry pie. from gh/s to bitcoins you have just for my own calculations? Thanks
You will never ROI, the price per gh for block erupters is very high, making it efficient for miners seeking for profits. You also need a usb hub to power the block erupter, dont forget about cooling and space. Buying a Antminer S4 would be a better idea than buying block erupters. Unless you are learning about bitcoin, donn't buy block erupters.
