I have a betfair account for a few year, however, as some policy modified recently, I cannot deposit to betfair. It is being too difficult to deposit money to Betfair now in some banned counties,
So any buddy have any idea of deposit money from some banned countries? Please sharing.

First of all, once your country is restricted, don't expect a good gambling experience once they've detected that you are using VPN. You can gamble with so many platforms and bypassing the prohibition of Betfair would just give your problems sooner or later. Also, why would you mind playing in it while there are tons that might be accessible in your country? All I want to clear here is that your funds might be frozen once they detected your actions, which is way worse than just playing on other platform.
