There are plenty of ad networks but most of them are stagnant these days. No real advertisers. I would be more interested to see if you can get good advertisers on board.
Well, I'd have to pour some of my own funds after launch, to be able to attract quality advertising and quality publishers.
I've got plans on how to attract real advertisers, it's just going to be slow, but, I'm not rushing anywhere
That won't be necessary, as long as you can guarantee an investor that his/her investment is good and safe. U don't need to put in your money.
I would suggest that the minimum amount for advertising should be low or equivalent to $1 in bitcoin. I'm sure u would get advertisers with that. If u make the minimum deposit for advertising too high like coinads, you won't reach out to the grassroots and Small Business Enterprise (sme)
