I say NO to PORN. Please. We all want to see Bitcoin in a better place. bitcoin has real valuable use. you can not do a good thing with help of a lie or bad influence. Try to provide services and in return ask for bitcoin. People will need to consume your product or use your service and you will get bitcoin. Bitcoin should not be used only as a way of Drug smuggling, porn, gambling, weapon dealing. Then in future common people will find btc as a coin of criminals, only. I would never use btc in porn industry
In the future? You should go outside more, sweetie. People already thinks that bitcoin is the coin of criminals. Right from the start, the people of the dark net are already using bitcoins for their illegal business. Bitcoin offers anonymity, thus, it's the perfect coin for them.
Right now, there's not that much bitcoin users. Let us fast forward for 100 years, the majority of people are most probably already using both bitcoins and fiat and are all starting to become aware that fiat is nothing compared to bitcoin on so many levels. Fast forward for another 100 years, everyone's using bitcoins. How do you think people are going to pay for the premium account or paid videos on porn sites? That's right, bitcoins.
TL;DR: Bitcoins will eventually be accepted on porn sites no matter how hard you try to prevent it from happening.
