You can upload soft content as free teaser and sell live sex shows / intimate pictures of yourself. You can use bikinifanatics as a way to promote yourself for free. Also, webcam models can sell their content just like on onlyfans. They get a 80% payout.
A significant number of men are members of bikinifanatics.com. This website provides tons of bikini pictures with beautiful women for a monthly fee. So, if these members spot your webcam model name in a title of a picture gallery on bikinifanatics, they may search your name on google and find that your work as a camgirl. This is an opportunity to get new customers. Usually, men who are willing to pay a monthly fee are likely to buy camgirl chat sessions.
I can see in my stats of my xchatz.com that people actually look for webcam models by typing their name. Be aware that every webcam model has a fanbase. The more content you have online and the better it is for your business as a camgirl. Furthermore, in the case of bikinifanatics you can keep control of your content. (You can delete it, modify it). Only paid customers of this website can access your content.
At last, bikinifanatics appears to be an onlyfans alternative. It is another channel to sell your content. The only constraint is to wear a bikini.
On your camgirl profile you can mention that you have a bikinifanatics account.
