Tinder bot – Worth it or not?

I've been searching like a freak on this topic.

Some say its expensive to get accounts some not..
Some say there are private bots…some say use chrome extensions etc..

Is here anyone that can go deeply in this?
What bots are there currently that works?
how much Do I need for lets say 10 accounts? I only see PVA vendors….but ppl are saying u need tokens? and shit..
