Betting sites are free to registration, you do not buy it.
Or I do not yet really understood you. Did you want to make deposit into your bet365 account and having problem with that all because your country is not supporting the gambling site?
If otherwise and only want to buy bet365 account, I will advice you not to buy it. From your country, there should be local options. What I did not like about bet365 is the fact that deposit rate is much higher than than withdrawal rate when converting dollar to my country's fiat currency in a way $100 deposited may not worth $90 when withdrawing exactly same amount.
I will advice you to make use of reputed gambling sites on this forum. You can check
gambling board to see some betting platforms that offer crypto payment directly which can be a good alternative.
