3 - How often can I transfer my account? What happens to my account after transferring?

An account can only be transferred once. As a goodwill gesture, your chips and stats are not removed from the old account, this way you can continue using them in the old game. For this reason though, it is not possible to transfer them again at a later date, and any further winnings you achieve in the old version of the game cannot be transferred at a later date but only used in the old version to enter games.
