You won't make anything.
It is not worth mining with a raspberry Pi,
Unless you are willing to use a 10000 block erupters.
I'm aware i won't get rich.
Just buy an ASIC man.
I my opinion, it's not as simple as that. First, the lattest Asics are quite expensive and the electricity
consumption of such devices are much higher. My goal, ATM, is to understand better BTC mining...
In fact i really wonder, whatever the devices people are mining with, if it's still possible to make profits...
I mean, even a Antminer S7 won't probably be sufficient in one or two years. Does anyone share the same
opinion?
Cheers,
Jeff.
