I think it's too early to engage in VALORANT Betting because this game is not yet as popular as, let's say CS:GO or Dota 2
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.
I had also thought something similar, normally the sites that exist are not in crypto format, they are all in another way of money, skrill at least I do not handle it or paypal, but I do not know if the creators of the game can adapt it to crypto and It can be managed through a gaming platform, I don't know how good it is to have it in a casino, I know it is very popular right now, I think it has become very popular after the pandemic or rather since the start of the pandemic It is when many people lost their jobs and began to look for other alternatives, and that option was born, however I would like some site to take this idea into account.
