I browsed through most of the crypto sportsbooks I know and even the ones including
here (also the exchanges) and unfortunately Betnomi might be the only crypto sportsbook offering a VAR market.
not sure which crypto sportsbook offers VAR market but I found this
article on a website talking about "VAR tips", at the end of the article you'll find a list of sportsbooks that offer VAR market(at least according to the website).
OP might not even find the VAR market in the list provided by the article because I skimmed through the first three and they didn't have it.
I actually do not get much clues about your questions but I would suggest you look at stake casino and see if you could get the answer to your question or you do a research for it.
Stake doesn't even have a market for VAR.
