These account is not verified.But you can play on exchange or poker.Do you understand me??? You can send this money to your accounts.
And do you think that betfair is dumb enough to leave the receiver withdraw the funds?
certainly not, don't even consider trying to withdraw them
or divert through betting or exchange to your account, you will get flagged immediately and might lose youe main account as well
the only way to use it is to try strategies with "real" money without depositing and only if he sells them dirt cheap
but they are not worth anything otherwise anyways
