I had an old Raspberry pi with a Bitmain Antminer 2GH USB plugged into it.
I have joined the bitminter pool and so far have 0.00000094 bitcoins. In other words, I don't expect to get rich.
Researching this question most answers take into account power consumption.
My question is, for this sort of setup that I have with 1 - 4 2GH USB sticks, if I do solo mining, do I have much chance of getting a bitcoin now and then?
