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.
If you have huge amount of bitcoin in your account, and you’re willing to give away some of it, then you’re good to go. Just know that if you’re trying to make an advert with the help of famous league, the result or impact would be highly exceptional but their fees are very expensive as well. That’s the reason why even a lot would aim for bitcoin global adoption easier and faster, the process is very hard and demands a huge amount of budget.
