Trading and auto claiming faucets are my only two method that give BTC at a regular pace. Trading with the price double, sell half method is a safe bet. I prefer margin trading or just normal trading with undervalued altcoins.
Faucets can give you free money but ask yourself if that is worthy of the time you will have to spend, I think it's better if you will do an online job or join a bounty campaign when you rank up, not only you will earn, you will learn as well because when you are more active in this forum you can read a lot of good information that will improve your way in making money.
