There is a balance between charging what you feel your content is worth and what the market says you are worth. For me, I did charge pretty high rates (and still do on MV) because I am typically far more conservative in my live streams and I very rarely post pics on Twitter. When I do post pics on Twitter, they're also very conservative. I also put a lot of time into my OF and ensured, best I could, that everyone felt heard and respected. I had 40 people, so I am not a "popular" model. I chatted with many of my people at least once a week and I learned about their lives, their fantasies, their fears, etc. What I offered on my OF was more than just lewds and occasional titties and orgasms and I feel that it all warranted/warrants my high cost. They clearly felt the same and I was in the top 5% before I made my decision to close down my page on the site. I charge(d) what I feel I'm worth, but also adjusted to the market. May need to adjust some more actually now that I'm switching sites.
If you have a lot of subscribers, you aren't able to develop and cultivate relationships like this, but you do have more eyes on your content so you are able to charge less. People who fit into smaller niches tend to charge more than those who have more broader appeal. I sometimes wish I had broader appeal because I do legitimately feel bad for having such high prices on things. I always did and do try to offer content that can fit into a variety of budgets, but some of my content is just super exclusive. I feel weird having someone pay less than $20 for a flash of my tits considering that when I was just starting out, I had people pay nearly a thousand just to see them.
Charging higher prices limits the amount of theft that you will have of your content. As someone who loves teasing and stimulating imagination, it can be damaging for me to have topless/nude content of mine out there for free. It's a huge turn off because I legitimately do get turned on by the thought of how I can make other people's imagination run wild. Higher prices also weeds out people who are just going to waste your time. For example, I rarely ran any sort of sale on OF. When I did, I would always get the same type of people. One person actually did a $5 chargeback on his sale subscription because I refused to post pics of my "gaping" asshole.
In my case, yes, my more expensive stuff is better than my less expensive stuff. I've always had good return on my more expensive stuff. For example, I sent out a $5 ptv - 25 people bought it. A week later, I sent out a $100 ptv - 6 people bought it. The latter is a much better return than the former. I did put significantly more effort into it and did something I had never done before so it was objectively better.
All this to say, please don't knock other people's prices. It's a little insulting to insinuate that an individual who charges a lot doesn't think about their prices. Everyone charges what they want and what they feel is best and reasonable for them. There are a lot of tits and pussy on the internet, but they aren't yours and that's what people are paying to see - your content because they like you. They are engaging in ethical consumption of porn and you should absolutely reward and thank them for supporting you and your work. But! you also shouldn't feel the need to lower your prices just to match what everyone else is doing in hopes of outcompeting them. Those people are not you.
