For Bitcointalk members we offer exclusive 2 Euros No Deposit Bonus ( please send email after successfull registration to info@nolimit365.com and write us that you come from bitcointalk forum ) So you're giving free 2 Euros for Bitcointalk members without any criteria? this mean user can create multiple accounts, brand new rank account, negative tag account, and scammer from 1xbit can participate as well? you will have many trouble since few months ago there's a new casino offer such no deposit bonus to Bitcointalk users, but they're disable it since they said many users are abusing this promotion.
You need to think twice before your casino might follow the same path like the casino which I mentioned before.
It's not advisable to give away 2 Euros for free but if they have a way to deal with the abuse of the bonus, they can try to do it and see how it goes. They can continue with other promotions if they can give good results because it is a way to grow the casino. Anything free is sure to trigger people to try to get it but at the very least, the casino should know how to deal with a surge in visitors after giving away that free promotion. Don't let them get a bad rating because they can't provide bad service to users.
Requirements is a needed so that they can eliminate those abuse that might happen to them. Abusing the giveaways given by a casino is not new here and it really cause huge error to the casino and it delays their operation so hopefully this will not happen here so better they set some requirements so that those abusers cannot do any nasty acts on new casino like this.
As long as these requirements can stop cheaters, I don't think casinos will have any major problems because casinos can control bonus abuse. We have already seen how this is implemented in popular and well-known casinos in anticipation of bonus abuse so new casinos can also try to practice this on their own. By doing things as other casinos have done, the new casino can continue its business well and have no trouble giving out other bonuses.
Hopefully, @OP can return soon because he made an ANN for his casino. This requires further management so that he can get more members playing on his site.
