I've been looking at how this project is developing for quite some time.  Indeed - it is unique. 
If any of the BTT users knows a similar project, then provide a link here.
I have not seen any analogues to this project.  Therefore, it will be very sad if devs stop promoting it. 
Because the idea of ​​the project is very good and original.

Marketing good or bad doesn't really matter. I have seen a "horrible" marketing campaign and that still worked because it went viral because of how horrible it was. Not here of course, not even in crypto, it was for a computer company (either dell or alienware) and it still worked. So, I would say that there is really nothing wrong with doing marketing and there is no wrong way. If you are getting famous for people complaining about you then it would be a horrible thing and it should not be like that but if you are getting famous for a bad marketing campaign then it still works.

This is why I believe that there is nothing wrong with it. I get that people are approaching things like this like it is some marvelous new discovery but at the end of the day marketing has always been the reason why some become successful and some don't. Even the greatest place ever could be developed by the best developers ever but if they lack marketing nobody knows about it.

There's nothing we can do but only hope for their success because everything would really be varying or depending with the demand and thats because of possible interest on the current updates that they had integrate into the site. Would it be enough?

As long there would be some people or new bettors/users in the site which do recognize this recent add up then its
better rather than have nothing at all.

This isnt only an overnight process but lets see on what would be the future upcoming steps to be made.

i believe this is not run by many people so they lack their marketing team here. but the good thing here is so far no complaints with withdrawal or anything. so for those playing on this site, it means, withdrawal is not a problem til now. they have unique betting system, the reason why some are attracted to this site. however, if you are worried about the longevity of the site, just bet on short term items.

Maybe they are not earning good revenue that's why they don't have any pasted marketing ads here, and if they just rely on people discussions well maybe this could make them go down for more but I believe they have something cooking on their minds knowing that this thread is alive and there business still up and running maybe in December month we can see special promotions since this is a good month to promote something cool stuff on your site.

If they already made a deal before, I think that will not be so hard as they can continue the previous deal and modify it with the current situation. If there are no significant changes to the prior deal, they can get an agreement quickly.

We do not know yet since they are not coming back here and telling us. But in their last reply, they told us that we should stay tuned for their news, so I guess they are preparing something for us.

They have running signature campaign before but they didn't sustain it and that is there wrong decision made since the other gambling site maximize their exposure after they decide to finish their campaign, but if they cannot sustain it due to unsustainable or they have limited funds well then this kind of scenario where people losing interest is kinda expected since people really find something fun or what makes them remember a certain platform which can possibly entertain them.

They are still marketing futuur here but of course not in the sense of advertising thru signature campaigns or events giving instead they are marketing in updating the new sets of predictions and come towards the reality of giving bitcointalk users an option to bet inside what is happening and what to come for this forum.
just like the recent posts of OP.

They literally have a bitcointalk betting ready there, I do not think that there were any other place that put in bitcointalk inside what they were doing otherwise. That is the biggest involvement of bitcointalk that I have ever seen. They also have other stuff as well then I have to say it is really not that bad of a marketing move for now.

I get that we may not be profiting from the marketing like we usually do with signature campaigns and all which makes some people bash the other marketing methods, but in reality I am sure banners and ads all around internet would be enough marketing for most places and they are probably doing fine.

The slightest promotion is the most important thing in running a gambling site, because then they can be attractive at least. But back to the casino itself or are they just running a smaller promotion? well with the same effect as what they do. Running a big campaign does cost money, but if you calculate it with the resulting output, it will be much more significant than relying on affordable promotions. Due to the lack of funds for the campaign, the results of the campaigns they have run are not in accordance with the targets they have set as a means of returning promotional capital.
