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.
I know quite a few crypto projects that have partnered with football clubs like digitalbits that was a major sponsor of AS Roma and Inter Milan before the deal was called off. OKX is a major sponsor of Manchester City, Atletico Madrid new sponsorship deal with WhaleFin, I could go on and on. Bitcoin is not centralized and it is not a governance token of a decentralized project that the community could come together and decide which football club to advertise it. Where is the money for the advert going to come from? So as you can see this is not possible, but a football club might decide to pay their players with Bitcoin but I don't know of any. Adoption might be slow but I believe Bitcoin is getting the attention and recognition it deserves.
