9gag clone

Hi, I have purchased a domain called bestviralgags.com Its about viral photos and videos. Already have all social media accounts registered. I want to build a websit elike 9GAG. How can I gradually build a website and community like that. I post good contents in facebook and boosting some posts...

I wanted to start up an image site like 9gag but with inspirational quotes I come up with and funny images from time to time. So I'm asking anyone with experience making a site like this, if it was profitable or not? Is it worth it to invest in a site like this now? Thank you. :D
