Honestly I would leave the adult niche while you can.
I run the website xFapZilla.com, Femdo.me, and xCatt.com and youfap.co I waste at least 5 hours per day posting on them.
Here's what 100,000 visitors will get you.
I started another website, it's basically Reddit.com mixed with buzzfeed.com.
The new site I launched is called UpVoat.com
Here's what about 1,000 views on Google Adsense pays.
Imagine if instead of wasting my time on the porn tube sites If I got 100,000 visitors to UpVoat?
Everyday i'm sitting here trying to post at least 100 videos to my tube sites per day making NOTHINGG. I think I might be insane.
I thought about shutting them down many times, every night as I go to bed I think about if it's even worth it.
I don't know what to do anymore. I really need to make a decision but it's hard to let go. I already have over 4,000 videos posted on the tubes.
