If the fan token doesn't have any benefit, the token will certainly decrease if something happens to the team or the current uncertain market conditions. Those who invest in fan tokens may support their team at certain events so they buy their fan tokens. But it's not easy to compete with projects with better plans than fan tokens, especially if it's only aimed at supporting teams from their country. I'm afraid the end goal of this fan token is just about pump and dump. Just my 2 cents.
These are mere tokens that doesn't have any value. Just the variation is experienced out of the market movements happening connected to the football matches of Brazil. Only the football fans find it good and enjoy to some extent while watching Brazil matches. The support from Brazil federation to have a fan token is really appreciable.
