All these are great advocating tips but the problem lies in bitcoin regulation by the government. Since the government is yet to fully support it this clubs will definitely be breaking rules by publicly advertising or advocating it.

Little intro to my context: It is a decentralized platform, it is a means of payment with very particular characteristics that make the individual have individual financial empowerment like never before, for anyone.

We can expand more on its qualities, premises and technical characteristics, but with the above it is enough to achieve adoption, I ask you, do we need more?

Now, any additional boost, as is currently the case with many brands or related companies: Exchange, restaurants, casinos and a large etc., is only an added boost for each of those brands, that is, the phrase; "use bitcoin," or "bitcoin accepted here," it is an additional hook for your services or product.

If bitcoin is promotion in a campaign like "bitcoin" without having an added service, it is a financial revolutionary movement, that has the added that any government tries to stop or prohibit that type of marketing idea, that is what makes it prohibitive in Many countries, they do not want empowerment.

The only one who has done that and has been able is called Bukele, he has used bitcoin in its essence as a financial premise for individuals and as a means of payment, hence, for now to any other country where bitcoin is allowed, for any type of advertising a product, it must have an associated service.

Anyway!. The adoption of bitcoin is a peaceful, idealistic movement, perhaps in the relevance of other historical movements that have arisen from individuals and that is where "you" as an individual develop it and sometimes depending on it you just have to be part of the process, buy, sell, hodl, trade and if you have more financial potential create ventures, e.g. such as goods and services businesses, then "You" add ads: use bitcoin here or bitcoin accepted here.

Do you think some of these have not been done?
Like I recall when some of the musicians wanted there shows paid for using bitcoin. I could recall snoop dog at a time. I had rumors of 50cent and even some basketball stars sorting out the option, at least a part of their earnings be paid in bitcoin. Surely it did trend for a while but then, away it went (@ the trend).
No doubt it pooled in some investors but still, we are where we are now.

Hence, even having bitcoin sampled on a billboard won’t change much. It’s already being done by the many casinos with football clubs sponsorship deals. The word out is how they use bitcoin in placing bets on their platform. Watford FC had it on their Jersey at a time but still, we are where we are.

There isn’t going to be any swift pace and nothing would promote bitcoin more than the bullrun so, just seat back and watch the times unfold.

Yes if every person uses Bitcoin massively the world will gain and rise as you expected. but, we have to not forget, that every country has rules that make Bitcoin forbidden to use, so that situation people who have Bitcoin in their wallet would find it and difficult to use it. They don't know how to invest his money into bitcoin because that country who have sponsor football league has banned bitcoin. I ever seen this situation, and hear their complaints about the situation.

I love your idea as we totally need more popularization ,
bitcoin needs all resources to be known worldwide and to force the government to finally adopting.
but all of these thing are "WHAT IF" because whales are only for their interests and that is to take our money out.
if this will be taken seriously , I think their money making machine will stop as the uses of bitcoin will serve according to its purpose , and not for holding only.
hoping that we will see some light on how you wanted it in the coming years but surely not in the nearest days.
and the promotion is the best concept of what he wanted to happen , because we knew how popular whales can be and
how they can popularized bitcoin in all sources.

yes, I agree with your opinion, because the most important thing is how people know the use of bitcoin, and I think there are still very few people who know the use of bitcoin, but with the internet now many people have started to know bitcoin, because on the internet now the name bitcoin is already familiar, but there are still many people who don't know what bitcoin is for.

I don't think that will happen. Companies, which are the most interested in doing that, are more likely to want to advertise a shitcoin than bitcoin itself, or their own company, as happened with the FTX Arena. To do so, it would have to be a billionaire who is a hardcore bitcoiner and doesn't mind spending the money on a sunk cost, probably for not much, as it wouldn't have much impact, as mk4 says:

The big whales putting adverts on football clubs be like "Invest money in my centralized crypto project. Trust me, I won't exit scam".
This sounds like meme content to me. Crypto.com is a big sponsor of sports events and I've seen their logo being placed on some football stadiums. Does this lead to mass crypto adoption? Nope...
Be honest here. You want crypto adoption mostly because you want the prices to hit the moon. You don't care about the poor bastards, who put their coins in centralized crypto scams and lose everything.
True crypto adoption will come, when the newcomers stay away from big crypto companies and keep their coins in their own cold wallets.

I've never come across a sports industry that directly promotes Bitcoin. But in Mixed Martial Arts especially in UFC (because I'm an MMA fan) I saw that there is a cryptocurrency exchange platform that is Crypto.com and a crypto project that is Vechain which has become one of their main sponsors. I think if BTC is banned due to regulations then there is no problem with cryptocurrency exchange companies promoting them to let people know about crypto including BTC.

Since the football clubs are not into cryptocurrency as a payment method and the volatile nature of bitcoin, it will make it impossible for them to pay their players in bitcoin. Moreover,since it hasn't been legally accept by the world as an alternative means of payment some countries that bitcoin is illegal will find it difficult to buy players from other leagues with bitcoin and vice versa. That is why you can see that these clubs are using the most common and valuable fiat currency which is USD for payment and for transfers. This is a nice idea OP but I believe that when the adoption increases as time passes by it might come to past.
