I would say it depends on your room flow, how many regulars you can trust to tip, the other countdowns, how much you can normally make an hour, et cetera. But most of all, I think I would base it off experience. If you are an experienced cam model, you can charge a lot more than 500 tokens a pop. If you are inexperienced or new to camming, it may be hard to pull in those tokens, regardless of what amazing things you can do.
