Just switch it.Do you have real account? And you have demo account.So, use same Metatrader to switch between them (between your demo/real accounts, between your accounts with different brokers').
Because demo account and real accounbt are not the same (you can not "switch" 1K demo to 1K real sorry).
If you have both accounts in your Navigator window (on the left hand side of MT4) just double click on the real account to swith from the demo one.
If you haven't logged in in your real account yet, go to File >> Log in to trade account, and fill in the account details you have from your broker (login, password & server) and click Login.
That is very "old news". Those conditions are no longer in effect and FNB (First National Bank), even makes a huge deal about their integration with PayPal services for their customers. So, there are no current limitations about RSA citizens having PayPal accounts. I know this because both my cousin and my sister, living in RSA, have PayPal accounts.
EDIT: By the way, following your own logic, how were you expecting to withdraw your "winnings" from MetaQuotes if you don't have a PayPal account (yet used it to charge your Credit Card do deposit the amount). Yes, because following your own logic you were "funding" your account via MetaQuotes and hopefully would be withdrawing the "winnings" via them too?
At long last thank you sir
