Champions League organizer UEFA is being criticized by supporter groups for monetizing engagement by partnering with a company that sells fan tokens through largely unregulated cryptocurrencies. The commercial deal was announced a day after the Football Supporters Europe group praised UEFA for giving away 10,000 tickets to the Champions League final this season, with thousands of fans also able to attend the other European club competition finals for free.
