Well, I confess that I'm not very familiar with Valorant...
Well, maybe I may be saying something silly... but do you believe that the Valorant game can have a huge success in betting? Even surpassing CSGO in terms of esports betting or something like that?
eSports aren't very popular when compared to traditional casino games and sports betting. With that in mind, I think it's going to be even harder for Valorant to overcome CS:GO in popularity, because these games are disputing a same niche of players, which is limited and restricted. As I see both games are also of the same kind and style, being Valorant created after CS:GO, so in this case Counter Strike has the benefit of the originality.
Personally, I would like to bet on another kinds of multiplayer games. RTS more specifically. But I have no hopes of it being possible, because I know RTS is one of the lowest demanded kinds of games in the world. They were popular in 90's and early 2000's, but no more.
