Would you consider in betting in Valorant games? Do you think it would be much popular, as betting in Dota2, in the future?
Yes, why not. I am into esports and I know how good valorant is. It would be much popular as dota 2 only if it met the satisfaction it gives to dota 2 players/bettors. Because as you have said, it is the same as csgo with a little twist just like overwatch, it means that the possible players/bettors might be coming from these popular games.
It's been sometime since the game was out and we don't need to argue that it really pique the interest of the players from other FPS like CSGO and Fortnite, but as time passes, players are now noticing these weapons, characters and strats that is OP within the game. They needed to fix these since it might affect the players and would affect bettings too.
