Some of these younger European cammers have found some success in getting tokens just by being cute or flexing. Most likely the tippers are hoping it will lead to more. The cammers think it will work indefinately. And sometimes it works for quite a while.
The real tokens come when you start showing. Hey_arnold used to make a lot from dancing and showing his butt. Then he started giving peeks of his dick head. Eventually he went full frontal and now that's all he does. Nobody lasts forever without showing.
I totally agree with you and many of us think viewers are on Chaturbate, CAM4, flirt4free... to see full frontal nudes without hiding anything. Many of us look less and less at these webcam show sites since they are so boring. Wasting your time to see a still handsome guy who doesn't show his cock and his buttocks is pointless. Might as well go to xvideos or youporn where there you have free videos of fucking and handjobs. Indeed many models have tried to scam people by showing little or nothing in public. They quickly understood that they earn a lot of money only by showing their naked bodies without hiding their dicks, in public shows. It's no longer private shows that make them rich, nor password shows, but public shows with public goals.
