This is interesting to hear about nft betting. Possibly it have been ongoing for long but not as popular as we think maybe the casinos that has this features should start making it public for gamblers to see and those that do not have should try adopting this gambling features an see how it goes.
I never expected to come across a question as this here but to seeing it being asked the then there is every possibility of such in existence and it would likely take a bit time for the adoption to be regular. I hope scammers would not use this as opportunity to start sending fake NFTs to peoples wallet luring them to transfer and clearing their wallets at the Se time.
