If you are sitting in one place and someone comes and meets you, there is a group in which people pay and they advertise bitcoin. Are you going to believe such a person as someone who holds this type of position in the bitcoin community? Because I can see that you are now a full member rank in this forum, which obviously means you know the answer to your question. However, bitcoin has already gained awareness, so how can you advertise a currency that is for transactions and an asset for investment? I think for you to be in this forum in this position, you need to be aware of this kind of thing that bitcoin doesn’t need to advertise.

However, people advertise what they know about for such things to gain recognition. What about bitcoin? That is already past that level of recognition; millions of people are already using bitcoin, so I don’t think such things exist.

Unfortunately there is no group that does this, we only do it when we feel it's going to attract new investors and we don't get paid for doing it, I have did this few times before, and later I relocate from the area, those who really saw meaningful sense in it later contacted me but the majority of them don't care.

I later stop doing it because too many people still believe that Bitcoin is a scam, I know a mother who told his son not to get involved in Bitcoin that it's a scam, without them knowing anything about Bitcoin, there are few other reactions from different people too, I am really not motivated to spread the news anymore.

Later it get to a certain way that I think it's not needed, I believe that Bitcoin is now more popular than ever, things are now different from what it used to, so whether people join or not they will eventually realize that they are missing out in future.

Why need promotion for bitcoin and there bitcoin owner is anonymous then who will spend money for bitcoin promotion. I have never seen any group that funds the promotion of Bitcoin. And never even heard of such a group.  Seeing your post today is the first time I know of anyone looking for such a group. Bitcoin does not need any promotion it is a coin that is already known to everyone.

It's not needed anymore because Bitcoin isn't a company. We are part of the ecosystem, and its demand will naturally make it popular. The idea of decentralization means that we, the users, essentially own the network. We don't have to promote it as big companies would. When they see people using it, they'll be the ones advertising it.

Additionally, the growing bull market is one of the reasons why Bitcoin will remain popular. So, there's no need to worry. Let it grow naturally through increased adoption.

Pretty much there is not any urgency to advertise bitcoin. A money spent for bitcoin is better flowed into supporting the ecosystem. Like funding bitcoin developers or creating a grants for bitcoin-related project. We know that the community better invest more to the developments of the project.

Directly advertise bitcoin is also currently not a necessity.

Yes, right. From its initial appearance to creating several sensations such as buying pizza using Bitcoin, Bitcoin was included in the list of safe haven assets until it entered the Bloomberg media and as you said, this was an effort to promote Bitcoin. And in my opinion Bitcoin is certainly not too concerned about promotion, because every good benefit generated by Bitcoin will gradually lead to mass distribution and adoption door to door or by word of mouth.

As long as Bitcoin enters and becomes a hot topic on television or the economy, Bitcoin promotion is still alive.

Like luxury goods and luxury cars, you don't need a lot of advertising, interested people will come by themselves.

Bees never tell anyone that honey is sweet, only those who know and are interested will understand the taste.

The best way to advertise Bitcoin is by incorporating it into your daily living, if you have goods or services you sell to people, accepting Bitcoin as a means of exchange is an amazing way to advertise Bitcoin also if you are a consumer of any goods and services opting to pay with Bitcoin is a unique way of promoting Bitcoin.
But most importantly telling people about the opportunities of Bitcoin not just the investment opportunity is a good way of not only leading people to Bitcoin but also it ensures they become enthusiast because many have sold of their Bitcoin during the dip and this has to do with how Bitcoin was introduced to them.

 
If there is an offer, I believe people will create groups to promote Bitcoin, but Bitcoin is not owned by anyone or group people but was created by Satoshi for the public to serve as an alternative to fiat currency for the freedom of privacy and other purposes. I believe it is individual contributions to Bitcoin in one or two ways. So with reason, that Bitcoin is not own by  group of people, so I don't think it needs a sponsor for advertisement but the work of an individual who is willing to help and promote Bitcoin by making people aware of it.

In fact, I don't think Bitcoin needs promotion again because if you go to many social media sites now, you will definitely find people discussing Bitcoin or find news about Bitcoin there. I don't think Bitcoin is new to people, but the truth is that it is going to be a gradual process of adoption because people need to get confused enough about Bitcoin before they adopt it, and I believe that people adopt Bitcoin every day despite the fact that there are still people who will give up because of scam activities in the cryptocurrency industry, like leaving their coin in exchange or for other reasons.

I think @OP want a promotion where it could gather a lot audience and it's not really about Bitcoin niche e.g. casino promoting through streamer, sport, Bitcoin wallet, etc which I'd say a creative promotions.

For Bitcoin, it's related to investment and making money online, but I think such way will not get a lot audience because they prefer to gambling as they realize now, the easy 100x multiplies wouldn't happen in Bitcoin anymore.
