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.

Why focus on Betfair when there are so many Gambling sites that has been legal in your country or the countries that you wanted to play with?
You can use VPN to Mask your country IP address but mind you that Gambling sites nowadays has many tools to Unmasked those who are using VPN so at some chances you will be banned forever and may made your funds permanently frozen.
So better think twice to continue following them or Find new sites to start your luck in gambling.
