Money Quote: "Renters can increase or decrease the number of coins in the wallet during the Lease Period, noting that the Closing Date will come without notice. That is the risk, you don't know when it will 'close'."

So the trick is to get IN to the Rental program while enrollment is still open and then keep at least three coins to remain active.

Enrollment will close tomorrow night at 1159pm CDT.
