If you spend your time to get Bitcoin, that really good as long you get enough profit from there, you can set this for your main job, even if you can work more time than usually I'm really recommended it because you will get the results later.
If some people say this is waste the time, that totally wrong or maybe they don't have enough experience/ knowledge to get Bitcoin, because this is not a easy thing.
If they just doing fauncet they will says if to get bitcoin is really hard and that just waste our time.
