How can you stipulate the probability of transfering balance over your account?
I do not beleive a betfair only user can release stucked balan e.
As long as your are officially concerned to betfais website, you can do this.
I'm not sure what it's like in other regions but here in the uk when you open a betfair account you get usage of the exchange, games and casino on the same account and you are able to use a single balance to bet on different platforms. Maybe I should have said betfair uk only as I don't know how betfair works in other regions.
