Persian speaking people are mostly located in Iran, Afghanistan and Tajikistan that sum a total population of 83+31+9= 124M total according to wikipedia.
Turkey speaking countries are turkey and azerbaijan that sum a total popolation of 83+10= 93M total according to wikipedia.
Now this forum have a separate sub-board for Turkey with 93M population but no sub-forum for Persian speaking people!
That is really not fair.
Not all Iran, Afghanistan and Tajikistan people is speak Persian, 124M total population isn't accurate. It's worth to mention the total population of a countries doesn't have any relation with Bitcoin forum, it's all determined on the activity and Bitcoin users in this forum.
County A has 1.000.000 populations, only 1000 persons interested with Bitcoin, and only 100 persons active in sub board.
Country B has 50.000 populations, but all persons interested with Bitcoin, and 10.000 persons active in sub board.
Of course Country B will have a local board since 10.000 persons has more activity than 100, it's just a example.
Persian population mostly on Iran, which is Bitcoin is not popular and had much adoption, as you can see Iran didn't included in this statistic.
What you need is make the Persian thread has a lot activity first, the chances will be bigger to get the official local board. Anyway don't ever try to spam, burst posting, or whatever to boost the activity, you could got temp banned or the chances will be less.
