So i have heard a lot of people saying you cant use bidtraffic on free blogs such as blogger and wordpress, does this mean i need to have a domain and hosting to make money? If not what other ways are there? and do they even check if it is blogger your clicks are coming from?

Thanks in advance

you can use bidtraffic on wordpress and blogger.
just request to be VIP and get your java feed and paste the html script to your blogger.
