I actually think that there is a certain demographic here on this forum that does enjoy CS:GO betting, but it's probably just a smaller niche.
Still, I've come across quite a few topics here in the gambling section asking about CS:GO betting with Bitcoin or asking about betting on e-sports in general.

I do think OP should post his picks anyway, there's going to be at least some interest.
There's certainly people interested in CS:GO betting, but I'd feel confident saying that there are people around here that would enjoy "Rock, Paper, Scissors" betting if there was a site or service to support it. I wonder how large that niche would be; I'd be willing to bet that it would be a similar size niche, so while I've seen with my own two eyes the interest in CS:GO betting I am not so sure that the interest necessarily stems from CS:GO. We have more desperate gamblers willing to throw coin at any opportunity than we have CS:GO fans hanging around the forums, at least as far as I know.
Again though, there definitely is interest in OP throwing their picks up here as I am one of those interested. I'd be willing to make small bets alongside, or at the very least watch the games live and keep up with the thread to make sure the picks are held to some degree of integrity. Not to say that OP wouldn't handle them with integrity, but of course it would have some weight if those of us already in the thread maintained our involvement to see this through, whether it's a bust or turns out to be the real deal seems to be our burden to bear at this point.
Still waiting to hear when OP will make their first prediction and I'm looking forward to reading their analysis.
