I remember the post being made before as well, these fan tokens are actually something that would help the fans to vote on certain decisions regarding the team. I do think it's gives you a little say regarding the whole team and how it would work as well, therefore I do think it's perfect for people who are dedicated to a team perse.
I do not think they would be used in gambling tho. It would be more like : designs that you might choose for their jersey, vote for other superficial things as well. For gambling I do think it's easier to use cryptocurrencies they provide you with more options hands down..also some people go so far as to compare these fan tokens with NFT's which might allow you to sell them as well.
