If a token is listed on an exchange it's a clear indication it has a useage and not just an avenue to collect money from their fans it's serves similar purpose just like every other cryptocurrency that has value
Every good token is been developed for a purpose and it's value starts appreciating once it's listed on a good exchange and this also is the case of this fan tokens generated by football club to support their fans and also get supported too in return.
There's a lot of pumps and dump coins/tokens in the market that became shitcoins in less than a year, getting listed in the exchange is not an indication that the coin is not going to be a shitcoin, platforms, innovations, and community adoption are what defined a good project, there are some football-based tokens in the market because there are innovations behind it and they are adopted by football lovers.
