To increase the System’s stability we introduce a new rule limiting the period of keeping confirmed Mavro in PO. It is active since the moment of this announcement publication.
If at the moment of confirmation, it appears that your Mavro were bought more than half of a month (15 days) ago, upon confirmation their amount with added percent automatically turns into Mavro-0%. It means that their further growth stops after confirmation. But you can cash-in them immediately and get all percent accrued during this time (prior to confirmation) in full (we suppose that every participant will withdraw all his mavro — why do you need Mavro-0% ? You could get all your Mavro with all percent and be happy :-)).
After that you can buy Mavro 30% again, it is allowed. But firstly cash-in those Mavro that you had!
Let's consider examples:
