Means that xlays have no deposit at all in the last year, so the deposit requirement is not related to the prize of the prediction contest.
Xlays need to confirm this, if he have made at least 1 deposit before then there is something to be fixed by chips but if it is true that xlays did not make any deposit during the last year, it is normal that he got the notification message.
Other prediction contest participants should also read about this general rule by chips so once they win the prediction contest, better to make deposit first (at least the smallest one) so they can withdraw the prize from the contest.
