price points for paysites in Euros?
 

what are the popular price points when charging in Euros for a monthly subscription to a porn paysite?

I don't know about popular price points. I can tell you from my personal point of view that I would never sign up for a site that's more expensive than 20 Euros. And I'd expect frequent updates for that kind of money.

Most sites I see just change the $ to EUR symbol
so 29USD is 29EUR, and it seems to work well

Most sites make the majority of their revenue in US dollar.
If your income from Euros is just a thing on the side, then yes, just switching the currency symbol might work.
29 Euros is a lot of money, though. Currently, that's US $40.

Whichever price shows the most Lifetime Value after 3 months of testing is the one you should use, not what some people on the internet tell you are the popular prices.
