Waiting for @Haneubu @teosanru to confirm. We have plenty of time so no rush ofc.
I'm fine with $30, but I still feel that $20 is the optimal starting point since lower fees could attract way more participants as some of the posters above pointed out.
The primary problem with the IPL is its unpredictability which is why it's very difficult winning any of these prediction pools which is why the higher fee could chase away potential participants. Lower fees could also attract Non-Cricket lovers.
How many people get a chance to win here? I see the OP thread and it says the top three predictors will get the prize money. As per stats here till now, you have seven people willing to participate and out of which 3 will definitely win some amount.
7* 30$ = 210$
This means 60% of this amount will be 126$ which will be given to the top winner.
In case of 20$ per participant:-
7* 20$= 140$ of this amount is 84$ which will be given to the topper.
The more you decrease the participating money, the less the reward, which may decrease the overall interest of the participants.
