I am also in favor that if a casino starts with a signature campaign, it is to guarantee success at a very good percentage, I do not have statistics, in fact I do not know if they are handled in the forum, but it would be interesting if they could be shown.
Yes signature campaign is one of the effective marketing to introduce a casino here in the forum. As we know those casinos (regardless if its new or old) who have a running campaign here are more popular compared to other casinos that has no campaign running. We dont have statistics to base on but its obvious that this strategy has a positive impact on their business resulting to its continuation even some of them has a short period initial plan for how long it will run.
Roobet is one of the successful casinos here and their different promotions from the past and present especially their art contest is like an appreciation for the gamblers who have talent to showcase.
I don't remember where I read it, but it was in a thread here on bitcointalk, where they said that those who decided to put the signature campaign had approximately 2 million visits, it was referring to traffic, I don't remember if it was daily or weekly, but to be like that It seems to me that it is much more profitable than doing in other social networks, because I know that in social networks there are some that offer traffic services, but most of them are bots, so what they can do is not healthy, what is needed in a casino is that it is totally legitimate for people so that they can arrive, spend, deposit, enter, win, withdraw, that is what moves a casino.
