You would feel really lucky if you got any of those NFT from Rollbit V2 sale which is anticipated soon because they have said some extra benefits this time but i would say if you are gambler on their platform then it would be more beneficial to buy it as most of them will be gambling related but on the other side you could make profits by selling it for higher price.
Extra benefits? What could it be. Many perks are already given to Rollbot V1 holders so if that is the case that would be more beneficial to those who wants to own a Rollbots V2. The good thing about this is, its open for everyone regardless if you're a gambler or not. Buying these NFTs are profitable if we based on the previous sales for V1 due to the increase of price on the marketplace.
Imagine doing things like getting higher cashbacks, or getting affiliate income but bigger, or getting free bets, or getting dividends. NFT could be anything, it is not art, or it is not some pictures or images, people keep mistaking the NFT art part with the whole NFT world. NFT is basically like ownership paper that says you own something and that is the proof, this could be for a house, for a music, for an art of course, for a book, for your chair, it is anything.
So, if you are given an NFT from a casino it means you are getting a utility regarding this situation, which results with the fact that casinos could give out anything they want to you, with a good NFT art of course but the art is the second stage of it and not the important part.
