I'm going to be living on campus for the next few years so I don't have to worry about electricity, and I was wondering if anyone could recommend a cheap and efficient miner that I can purchases. I can spend around $100-$200 starting off. I'm not planning on hardcore mining just something productive going on while studying. I was also wondering if anyone could recommended what type of currency I should try to mine? I'm still studying a little about Bitcoins, but have yet to set up a rig or even mine any type of cyber currency.
