I run 4 accounts of 1 niche with 3 sub-niches. I started with one account till that one was around 50k, then I knew how to grow other account fairly quick without spending too much time. Therefore, I would say start with one and make that one excellent first
I have a question. Do you maybe know how this account (www.socialblade.com/instagram/user/bossgirlsempire/monthly) get on average 10k followers a day and max 15k a day.. its crazy. They spam the shit out of instagram, however will this make you grow this quick?
