adult facebook group traffic conversion, does it worth it ?

I started my journey of adding adult targeted people to a Facebook group I made, right now it seems like I can get 1000 members/day , I'm going to wait for the group to reach 20,000 members then start promoting my affiliate links, for the experts in this, do you think it worth it ? should I continue adding people to the group ? will it convert well at the end or am I wasting my time ?

I think it will be worth posting your links to other adult groups, there are a lot with each having more the 20k members. Get in 50 groups and youl will have a lot more reach. If you know a tool that will automatic post into groups it will be great. I'm searching for one right now.
