I think it's really hard work.
It is not just by working hard, but also by working smart. Hard work pays quite alright but there are some information that can really help you to make even more. It is just to find them, find out where one fits in, pay your dues with some extra effort and get your pay.

making up to 1 or 2 Bitcoin in a month is not easy. Even now, I stay awake through out the night some days, but I cant even make up to 1 Bitcoin most of the times. You need to work hard, and also look for bigger opportunities. You dont put in 2 hours and expect up to 1 or 2 Bitcoin.
