You don't have any bitcoin but want to know how it works?
If you want to get into bitcoin without buying any just to see what it's all about, download a bitcoin wallet like Multibit and make a bitcoin address then simply goto a site like http://freebitco.in/?r=513 . You can build up some free bitcoin and they will get sent to you at the end of the week. No need to spend big just to get an idea what's it all about!
