Unfortunately mostly faucets and odd micro jobs. I figure in my down time at work if they keep me busy, so be it. I don't really have a skill that's marketable via the internet .. ie: graphic design or the like.
Faucets are a waste of time and waste of electricity. They are meant for people who have just obtained a wallet and want to get some small amount of coins to start its transactions - that is know how bitcoin works and start transactions on it. But its not a method to get rich.
Jobs that pay you in bitcoin are the best and thus people should try to market the skills they have in freelance sites and other professional fields - not only in bitcoin but also fiat.
Trading is another good source and signature campaigns are side earnings.
