Depends on how much you mine. Doge coin of all things was up a few months ago, friend cashed in an iphone 6 by mining on his old phone.
Electricity costs more than the bitcoin you receive. However if you are in university halls etc (Power has a flat included rate) Then it's probably worth doing.
Depends. You're really not going to get anywhere with it unless you invest some serious $$ into the hardware capable of doing it efficiently.
