It's probably far less than 5%. Most of the people who view porn sites are only there to view porn. After they have viewed it they aren't thinking straight and are unlikely to pursue intellectual questions like "what is Bitcoin".
Hmm.. I don't agree with your argument 100%. The guys will be there initially to view porn. But at least some of them will be noticing the fact that Bitcoin is a rapidly growing market, and investing in the BTC can make them filthy rich in the not too distant future. Most of the people who are addicted to porn, are also addicted to money.
Then all the rich people in the world are porn addicts... Now that is a interresting concept.
The statistics I posted in the previous thread about this, surely shows that most of the USA are porn addictics.
{just joking.. before you bite my head off}
When someone view porn, they look at the details... some things are suggestive .... If you put the Bitcoin symbol between the breasts, they might miss it. If you put it on the nipple and other strategic spots, and you tell them, to pay to expose that spot, they might just be intterested to find out more.
BUT porn is everywhere...and it's FREE... So you must have something VERY interresting to motivate them to "remove" that Bitcoin symbol.
Sex sells... If they use Bitcoin or PayPal or Credit cards or cash... It's all the same... IF they use Only Bitcoin, it becomes a problem.
