Different sites tend to have very different traffic from different sources. As far as I know now, Bonga is a site that feeds mainly on advertisements on tube and porn sites with a predominantly Eastern European and Russian audience. They do not necessarily open an account and do not necessarily pay at all, since they are not yet the target audience of the site, plus the solvency of the country where the traffic comes from is very important. Bongacams models mostly speak Russian, American and European members do not always stay on the site for this reason.
