I don't doubt it. He would need to double earnings and go public again. I suspect the users with a large following are going to have to start paying for it through subscriptions. That and setting up a better ads platform will get him to double the earnings without having to double the user base. If he does it in less than 7 yrs the investors should be very happy.
I mean, he's gotta have plans to monetize it somehow. I'm curious if he has aspirations to turn it into a payment super app like you see with WEchat in Asia.
