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
Short answer to this question at present bitcoin difficulty level is:
Forever minus a day or two (depending on luck) :p
In other words, it ain't gunna happen in your lifetime.
