Sports and music can have a big and important role in the dissemination and development of the Blockchain in general, and not Bitcoin in particular, because as far as I know, no sports clubs or music companies have adopted Bitcoin, but rather they have made their own coins, most sports and music teams have their own tokens that their fans buy To make donations or buy tickets, team products, etc. to support the team through these tokens. So I don't see any significant role these sports and music teams could play in the adoption of Bitcoin.
Honestly that means they have been part of the blockchain revolution and that is fine enough for me. Having your own token as a sports club means that you could actually give part of the club to the fans, and in return they would have some say in the club. That’s a good thing, it allows people to be part of something bigger.
Like the rewards system, they could buy a good number of tokens, and then get tickets cheaper, or a jersey for cheaper, or could buy some tokens and meet a player etc etc. These are all great incentives, giving the team a good amount of money, and also making the fans a lot happier to spend their money knowing it goes directly where it should be.
