If you can then you have to start a blog or any website and work for that blog the most and collect and provide interesting contents on that blog and increase its traffic so you will earn a good income from that blog by showing advertising banners on there.
There are some people earning thousands a month, or if really popular then even weekly through blogs or vlogs. Each of us is reading or watching them, but YouTube beats all the others in my opinion. However, you need to be charismatic to join YouTube and earn a living out of it, or have a crazy idea that will get viral. But speaking about Bitcoin, Anonymous Ads is probably the most popular Bitcoin ads provider existing around, they don't even require any type of ID.
