Crash hunt competition in games and round sections would be an excellent addition. I am sure players would like to play in a casino with such a low house edge. This platform needs a little more exposure all over the forum and the internet as well.
Competition is always nice but I think it should be also available on the site. They can run special bitcointalk competition although I'm not sure if the interest will be good enough. As proven by many other competitions in this forum, the number of participants is not that big. We have so many active members in the gambling board but only few of them are real gamblers who will be willing to participate in such competition. On site promotions/competitions will be a better option to give something back to real players.
I have dual feelings for this because I have seen the best of both worlds. This forum is full of gamblers but not all are involved in the competition and that's true but it is also true that most gamblers would take the role of watchers. What I mean is, that they would usually just check how these participants are doing in the game and see the fun from their desks. However, this slowly causes them to think about the casino and they also start playing the casino on the official site. This becomes an indirect type of marketing for most of the gambling sites and I think it is still good.
The other way where casino launches promos and codes on their own website is also best since it's happening under the official domain and most of the players do like it that way for better confidentiality and trust. I think its fine both ways the MoneyPot chose.
It is just the question of how much importance to which type of promo?
