Excerpt from the most recent version of "Prizes and Awarding Rules":
"If Participant does not have a live account with Dukascopy, then he/she should proceed to the live account opening procedure in a regular way. If Participant does not comply with live account opening requirements, Dukascopy reserves the right to cancel the cash prize.
Cash prizes may be credited only to a live sub-account open with Dukascopy in the name of the relevant Participant.
LIVE accounts which are credited with prize money are considered LIVE Prize accounts. LIVE Prize accounts can be credited only with cash prize money. Clients are not allowed crediting their own funds on this type of account."
