I agree with sunsilk as long as is free and doing it for fun but in reality like the sunslik said of course there will be money involved in this kind of scenario hahaha 
I mean some people want to get rewarded when their guess is right. 
and yes I saw a lot of sports nowadays accept crypto for their sponsor even the biggest like Bybit on F1 Team is just freaking cool. It not only do people get attracted to crypto but also I just feel proud that crypto company started sponsoring those cool sports teams.
We'd see more of these often and exchanges that become casinos and sponsor any team or athlete for them to have exposure. We've seen this already and buying the name rights of known stadiums.

Huge money is getting in but I don't think such free things in this world will be enjoyed by most of its users.
This is cool if it is free and real. But speaking of reality, there is no way to gain and win right predictions without having to bet with real money.
So, it isn't cool at all unless there is some conditions from the exchange that you are advertising and that is an incentive for specific accounts and users that has spent certain threshold.
Besides, I've never seen an exchange that sponsors a football club doing a prediction contest, it doesn't exist I guess, exchanges are more focused on other things not guessing match scores.So, it isn't cool at all unless there is some conditions from the exchange that you are advertising and that is an incentive for specific accounts and users that has spent certain threshold.
Except for casinos sponsored by new clubs, there are many prediction contests, and this is not easy, it is not completely free, there must be a wagering requirement to get a withdrawal from this contest.
