I agree. Not just big players like business owners and investors. When celebrities and well known figures also join in majority of their fanbase would sign up to.
Celebrities would use this platform to better monetize their products and their fanbase would be delighted that along with supporting their idol they also get monetary incentive to do so. I mean when did Facebook or Twitter do that for them?
I think the celebrities and well known figures you talk about would still be a bit skeptical at this point. Imagine them having this reputation and then endorsing something that sounds like a scam, so some of them may be interested but I would guess they will but not anytime soon. So hold on to that penguin gif for the mean time. ;)
