By the way, the fact that these pools will last only a month is not a disadvantage, but on the contrary, a plus - traditional pools are difficult for many precisely because they require attention for 9-10 months.
I am not talking from participants point of view. I am talking from sponsors point of view 
For participants it would be best if we had 2.5k money for each game, wouldn't it? I know I would prefer it that way.
Idea is to offer enough back that we have sponsors in the future. That means posts, views, extra activity in the thread/telegram, something that Sportsbet can measure and appreciate.
When you look from their perspective and cost per week metric, this month long pools are giving back way less then seasonal ones.
