All right guys im new here so go easy on me but anyway i want to know if its possible to mine bit/lite/etc coin using Rasberry pi and a usb miner on the stlye like Butterfly Labs BFL Jalapeno and make a somewhat profit. Thanks
If the bitcoin mining difficulty is going to rise at 15-20% or more (like the past year) each time, I don't think any existing ASIC could give you profit.
BUt if it is going to rise at ~5% each time (like the previous 2 jumps), it could be profitable.
