[Launching Promoted Gigs]

I think in the same way as you, the Gig need at least 30 review, okay… but i would like to promote my second gig who give me more revenue per order, i don’t wanna promote my main gig just because have more reviews

That’s exactly what I have in mind too! I was thinking to create another gig and promote it, but then I read the “30 reviews” rule 😦

[Can i use two fiverr account using same wi-fi connection?]

It is safe. As long as you are working in different computer, different account and different payment account.
