As people who are already having experience with tournament waggering.

You don't need to worry, once mostly in the end of the days or few hours before tournament ended. There will be have someone who boost the their account for waggering at least take some those spots without losing anything.

No need to ask, what happens for those 0$ waggering. The tournament is not ended yet, and most the time few hours before tournament ended or few mins before ended. Someone will boost waggering of their account.
