I am pretty sure that most miners just save their Bitcoins. It is probably the best idea as you will get more money as time goes by and the price of Bitcoin rises.
That is right. I save most and only sell some to pay for the cost.
Mining gives me far too few btcs that i tend to just forget that i'm mining coins. I don't think it would be worth the effort you'll put and the fee you'll pay for such slow accumulation. Though in time, when i forget about it, i still earn without doing anything. Just leave your miners and get back to them after some time and don't put too much focus on them
