The best thing to implement if casino want to give birthday bonus is not based on the date when the players were born but the date when the players created the casino's account. This way, KYC is not needed at all but it is indeed a rare thing to find casinos with such bonuses.
Good idea and somehow agree. One of the unique promotion ideas I guess. Like a loyalty reward or perks for continue using the site.
If implemented, I just hope that the required wagered amount to be eligible for that promotion, throughout the year isn't that high or difficult to achieve or if possible, not just about the whole amount wagered within a year but for other activity as well.
