So,basically for BTC you guys suggesting the USB miners in bulk/ like 100 piece instead of the unsure other basic options ?
let's see, for $1000 you could get maybe 30 max, 10 g/hash.
At current rates (or last I checked) that would produce one bitcoin every 6 days, so IF THAT STAYED CONSTANT you'd get 15 btc in 90 days.
But it isn't going to stay constant, so the return might be half or 7.5 btc...
