Day by day increasing the rate of bitcoin to high. Hope it will be reach 10000$ at the end of the year 2017. If you set a goal to earn a little amount of btc every day, it will be a big amount after a targeted time. you can earn one bitcoin within three or four months. You have to set a long term goal to achieve it. suppose, after six months working result is one btc=6000$.Is it not sufficient?
