Silver vs Gold Leaderboard

Hi,
I was wondering what is the difference between Silver and Gold leaderboards and how do I get into them. I know that you need the sostronk subscription but would i get into silver or gold? or is it only lifetime subscribers get to gold?

Subscribers start from Silver and from there they compete to get into Gold (and then compete in Gold to reach Next). There is no difference between regular and lifetime subscribers as far as leaderboards are concerned.
