Sorry, but I have not enough knowledge about broker of any gambling sites. And I do not trust anyone on the telegram who send me message for first time. I first try to understand who is the person then try to make any transaction if necessary. And for gambling why you have to deposit via telegram by a broker? Who stopped you to deposit via the website? If you are restricted for your country then you may check their shadow sites and/or you may use vpn. But you should not use any broker on telegram.
