Another thing worth mentioning is recurring payments. Many of these porn sites make money off recurring payments. Many people sign up with credit cards and then let it auto renew. None of the porn sites I've seen have a great way of renewing a membership with BTC. It's clunly.

Unfortunately It's hard for companies to understand that by offering Bitcoin they are getting NEW customers that they wouldn't have received before, not losing customers to a lower LTV payment method.
