thanks steamtime, electric doesnt cost me anything as i live on a farm where electric is paid for by someone else.

Hey guys, im new to this and want to have a little fun by trying mining, i have a macbook pro 2015 and looking to get a usb miner to start off with and came across a Bitmain Antminer 2 GH/s.

would this be recommended to use on my laptop to start out, bearing in mind my electric doesn't cost me anything, how much do you think my potential return per week could be?

Thanks,
Gav
