Are Football Fan tokens halal to invest in?

Salamoe3alaikoem all,

What do you think about football fan tokens such as the tokens for FC Barcelona and PSG? Are these halal to invest in? I have been waiting to invest in this until I know if it is halal or haram.

There are a lot of coins in the cryptoworld, but football is something I actually understand. “Stick to what you know” is my plan.
