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.
There are promotions already going on that puts bitcoin in the mainstream like when casinos partner with a sporting club and has Bitcoin logo as the casino logo or when everyone knows that casino as a Bitcoin casino because of their name or other advertisement they have seen about the casino promoting bitcoin usage for gambling. We already have many Bitcoin advertisment and many more will be launched soon as we're getting closer to the bull market.
I don't think we should be forcing people to know about bitcoin through advertisment or we'll be sending them the wrong message on what Bitcoin is all about and that's why we're getting more of short term investors only joining because of the profits they want to make.
