It's purly depends upon domain age and keywords search volume...

25–30 backlinks per day is safe for a new website on average.

I would like to suggest that you do not focus on the quantity of links . You should focus on the quality of links. I think you should get a few backlinks, but quality backlinks.

20 to 30 Links are comfortable per day to increase your site ranking.
