I just thought of this, and I want you to view it from your own perspective. As everyone hopes that more people get to believe and use bitcoins, I think bitcoins can gain more new users on a large scale if anyone (whales ) can place their advert through a popular football club just as some companies do sponsor football league. I think this will send a strong message to billions of people across the world who do know but does not embrace Bitcoin usage.
Let me site another example, let's take for instance, a club announces that they will pay their players in BTC. This news can also help people adopt BTC.
It seems like an interesting idea, of course if BTC has been widely adopted for now it will only take time for people to trust Bitcoin. Well, if the community understands on the other hand, this condition will have a positive effect because the market potential and business space will increase wide open means that they are not only market objects but also have the opportunity to become actors and make a profit.
