Of course, most people will recommend running a signature campaign, the casino has cryptocurrencies, this is a forum about cryptocurrencies, that is, here in this forum are potential customers, knowing that many people on this forum spend money playing games, then run a signature campaign a good idea if it is well planned, let's look for example at this ann thread, if you had to signature campaign in this thread there would be many posts from the participants of the campaign and it would be talking about casino games, that would be a good thing
I can assure you that signature campaigns aren't just for this forum users alone, this forum has a good search engine optimization which makes it appear on Google when people out there search for stuff on Google with the right keywords, this makes the forum get millions of visitors everyday, as this visitor visit thread, read comment, they are also watching the signature and they can click and sign up on any of the platform they pick interest in from the signatures..
I am sure that if the signature ads were basically just for the users of this forum, alot of casinos would have preferred to just advertise their business outside the forum, or the signature ad spaces wouldn't have cost as much as they cost currently, depending on forum rank.
