If you answered this two years ago yes but two years has passed already and valorant is now a popular fps game along with cs go and dota 2. I only don't know if valorant is now available for betting on many sports betting sites but they better add it now if they haven't yet since the game has a potential. Many people are playing it, and this can bring extra traffic/income to a betting site.

The OP has attached some sites on which valorant betting is available but I see that those sites only support fiat and other centralized payment methods like credit/debit card, skrill, and alike but how about those who wants to gamble privately and only use a crypto? Hhmm.
