I'm not talking about the wagering competition but I'm suggesting for the current on going competition to be changed a bit especially about the prize distribution to make more challenging, where players keep on betting to collect entries till the end of the competition. The current on going competition makes participants stop betting once they collect the required entries.
Keep betting to collect entries?
Off course they will stop when reached a few ranks, the reward and how the competition goes is just the same and normal like average casino. It's not lottery when the winners were based on how many entries/score you have so makes you must to always play to get more chance become a winners. Also not every people always have a fund to keep playing on the game we cannot control the player need to always play on the CASINO could be he losing when joined the competition and decide to stop. If he plays for only the COMPETITION and already secures his rank, it's up to him to always play or not since he already secure, however when someone overtaking his rank there has some chance he playing again to leads against other people who lead his rank and add more wagering amount to make his rank more secure.
Challenging or not, if you put hard rules and other things could lead your competition not going very well as you expected. Everyone like an easy tournament and not really like it when is hard or challanging.
