I've Got It
yea it's looks silly that having a big amount of subs would get ur viewers to hit sub but it's a fact and u gotta deal with it.what if your doing everything right, thumbnails, tittle, description, tags, 108060fps....and you still don't see any major changes? how are we supposed to attract todays audience that to be honest won't care about channels below a certain amount of subs?
Don't expect to see many changes in short time, keep growing ur channel the way u r doing now and after while u would feel the sucess for sure.
just don't give up and keep going.
